For example, due to changing track conditions or other variables, such as tire wear, different Racing Modes can be Selected at any time to change your Model's setup. A number of functions, such as Dual Rate, Exponential, Curves, Compensation Mixing and more, that might commonly be required to be changed during the course of a race can be programmed with different Programming Values for each Racing Mode. This ensures that your Model can operate with the best-suited setup for ever-changing track conditions throughout an entire race, giving you an advantage over other drivers.Functions can be programmed the same for all five Racing Modes or functions can be programmed independently, allowing you to have different function Programming Values for each of the five Racing Modes and switch between them while driving.OFFOFFR1 R2 R3 R4 R5GREENMAGENTACYAN YELLOW WHITECOLORLEDMODEActive R-MODE LED Colors:In the default configuration, after Activating the Racing Mode function, you can switch between Racing Modes using the Racing Mode Switch (Trim Switch Trm4). The R-MODE LED will change color to indicate the currently Active Racing Mode. In addition, the currently Active Racing Mode will be displayed on the STATUS screen. When you switch between Racing Modes, the currently Active Racing Mode will be momentarily displayed in a pop-up window.Racing Mode functions will vary depending on the current Car Type. For a complete list of Racing Mode functions based on Car Type, see the Racing Mode Functions by Car Type table on page 99.Turning Racing Mode ON and OFF:1) From within the RACING menu, scroll UP or DOWN to highlight the R-MODE menu.2) Press the ENTER key to open the R-MODE menu. R-MODE > INH will be highlighted.3) Press the ENTER key, then scroll UP or DOWN to choose the desired R-MODE value, either ACT (Active) or INH (Inhibited/OFF).R-MODE setting range is ACT and INH. The default setting is INH.

76M12S 2.4GHZ FH4T RADIO CONTROL SYSTEM USER'S GUIDER-MODE MENU {RACING MODE}RACINGTurning Separate Functions ON and OFF:When Racing Mode is turned ON (R-MODE > ACT), various functions can be programmed the same for all five Racing Modes or they can be programmed independently, allowing you to have different function Programming Values for each of the five Racing Modes. For example, with D/RST set to ON, you can choose a Dual Rate Steering percentage value of 100% for Racing Mode 1, a Dual Rate Steering percentage value of 90% for Racing Mode 2 and so on. 1) From within the R-MODE menu, scroll UP or DOWN to highlight desired function you would like to turn ON or OFF.2) Press the ENTER key, then scroll UP or DOWN to choose the desired value, either ON or OFF. When set to ON, you will be able to choose different function Programming Values for each Racing Mode. When set to OFF, function Programming Values will be the same for all Racing Modes.SEPARATE functions setting range is OFF and ON. The default setting for all functions is OFF.3) Press the ENTER key, then repeat steps 1 and 2 to change any other desired values.Switching Racing Modes to Program Separate Functions:If you've chosen to program one or more Racing Mode functions separately (as described above), a Racing Mode Icon will be displayed within the specific function Programming Menu to indicate which Racing Mode you're currently programming the function for.To program different values for each Racing Mode, make sure to switch to the desired Racing Mode first. For example, with SEPARATE D/RST set to ON, open the D/R menu. An R1, R2, R3, R4 or R5 Racing Mode Icon will be displayed next to the Steering function, depending on which current Racing Mode is Active.Use the Racing Mode Switch (Trim Switch Trm4) to switch to Racing Mode 1. R1 will be displayed next to the ST > 100% percentage value. Choose the desired Steering Dual Rate percentage value for Racing Mode 1, then press Trim Switch Trm4 to switch to Racing Mode 2. R2 will be displayed next to the ST > 100% percentage value. Choose the desired Steering Dual Rate percentage value for Racing Mode 2. While you're driving, you can now switch to different Dual Rate settings simply by switching Racing Modes.The Racing Mode Icon will only be displayed for Programming Menus within the RACING menu and only if the specific function's Separate value is set to ON in the R-MODE menu. If no Racing Mode Icon is displayed, the function Programming Value will be the same regardless of which Racing Mode is currently Active.D /R MENU {DUAL RATES}RACINGThe Dual Rate function allows you to change the control authority of the Steering, Throttle High Side and Throttle Brake Side by changing the amount of servo travel relative to control input. For example, by Increasing the Steering Dual Rate, you can make the Steering servo travel more which might prevent your Model from pushing during turns. If your Model oversteers during turns, you can reduce the amount of Steering Dual Rate.IMPORTANT: Prior to programming the Dual Rate function, you should adjust the maximum Left and Right (or High and Low) End Points. For more information, see the EPA Menu section on page 62.In the default configuration, Trim Switch Trm3 controls Steering Dual Rate and Trim Switch Trm5 controls Brake Dual Rate. Throttle Dual Rate can be changed while you're driving by Assigning the Dual Rate function to another Trim Switch or the Auxiliary Dial. For more information, see the ASSIGN Menu section on pages 33 ~ 38.Current Steering, Throttle and Brake Dual Rate percentage values are displayed in the Lower Right corner of the STATUS screen.

77M12S 2.4GHZ FH4T RADIO CONTROL SYSTEM USER'S GUIDETRChanging the Dual Rate Percentage Values:1) From within the RACING menu, scroll UP or DOWN to highlight the D/R menu.3) Scroll UP or DOWN to highlight the desired Dual Rate percentage value you would like to change.4) Press the ENTER key, then scroll UP or DOWN to Increase or Decrease the Dual Rate percentage value. Increasing the percentage value will Increase servo travel and Decreasing the percentage value will Decrease servo travel.5) Press the ENTER key, then repeat steps 3 and 4 to change any other desired Dual Rate percentage values.DUAL RATE setting range is 0% to 100%. The default setting for all channels is 100%.2) Press the ENTER key to open the D/R menu. ST > 100% will be highlighted.Dual Rate is a percentage of End Point Adjustment. For example, if you set the Steering Dual Rate percentage value to 100%, the Steering will travel the same amount defined by your End Point Adjustment programming. Alternately, if you set the Steering Dual Rate percentage value to 50%, the Steering will travel half the amount defined by your End Point Adjustment programming. D /R MENU {DUAL RATES}RACINGTRIM MENU {SERVO TRIM}RACINGThe Trim function allows you to view the current Trim value for each of the four channels and, if desired, allows you to change the Trim values using the Push-Button Rotary Dial from within the TRIM menu. For example, if you don't Assign Auxiliary 1 Trim to a Trim Switch, you can still Trim the Auxiliary 1 channel from within the TRIM menu.The M12S features Digital Trim Memory. Any amount of Trim that you set during use using the Trim Switches or through the TRIM menu is automatically stored in memory for that specific channel and for that specific Model. The Trim values for each Model will automatically be loaded when the transmitter is turned ON.Each time you move a Trim Switch a short audible Tone is heard. When the Trim value reaches 0 (Centered), a longer audible Tone sounds. This indicates to you that the Trim is centered without the need to look at the transmitter.In the default configuration, Trim Switch Trm1 and Trm2 move the Steering and Throttle/Brake Trim in 5% increments. If you want to Increase or Decrease the Trim Resolution, see the Changing the Trim Switch Step Value section on page 35. In the default configuration, Trim Switch Trm1 controls Steering Trim and Trim Switch Trm2 controls Throttle/Brake Trim. Auxiliary channel Trim can be changed while you're driving by Assigning the Trim function to another Trim Switch or the Auxiliary Dial. For more information, see the ASSIGN Menu section on pages 33 ~ 38.The current Trim positions for all four channels is shown on the Trim Displays on the STATUS screen. PRO TIP: The Trim function features two different Trim Type options that you can choose from. Choose from either Center Trim or Parallel Trim. For more information, see the TRIM TYPE Menu section on page 43.

ST > 0 will be highlighted. 3) Scroll UP or DOWN to highlight the desired Trim value you would like to change.4) Press the ENTER key, then scroll UP or DOWN to Increase or Decrease the Trim value in the desired direction.5) Press the ENTER key, then repeat steps 3 and 4 to change any other desired Trim values.TRIM setting range is 0 to 100 in each direction. The default setting for all channels is 0.Before changing the Trim values, you should first verify that all Trim values are set to 0, then adjust the servo Sub-Trim values to center the servo horns perfectly. For more information, see the SUB TRIM Menu section on page 63.CURVE MENU {EXPONENTIAL, ADJUSTABLE RATE CONTROL AND CURVE}RACINGThe CURVE menu allows you choose what method you would like to use to vary the amount of servo travel in relation to the amount of control movement. Choose from Exponential, Adjustable Rate Control (ARC) and Point Curve functions. Each of these three functions offers something different, and which function you choose to use for each channel will be determined by many factors, including your Car Type, track conditions, driving style and more.Exponential, Adjustable Rate Control and Point Curve functions can be programmed for each of the four channels. Programming options will differ within each function depending on the specific channel you're programming. For example, if your Car Type features Front and Rear Steering and Front and Rear Motors (such as Car Type X), only ST and TH channel options will be programmable, however, both Front and Rear channels will be programmed with the same Programming Values.Exponential ProgrammingThe Exponential function allows you to vary the amount of servo travel in relation to the movement of the Steering Wheel and Throttle Trigger (or in some cases, the Auxiliary Dial and/or the Auxiliary Lever) near the Neutral positions to change the way those functions react to control movement.Decreasing the Exponential Rate percentage value will Soften the control feel around Neutral and Increasing the Exponential Rate percentage value will Heighten the control feel around Neutral. Using a Lower Negative value allows for smoother control. Using a Higher Positive value may result in more 'twitchy' control response.Quick(1% to 100%)Linear(0%)Mild(-1% to -100%)100%100%NAmount of Servo OperationAmount of Control OperationA graph that depicts the control output and Exponential Curve relationship is featured to help visualize the changes you make. Exponential Programming Values can be changed while you're driving by Assigning these functions to a Trim Switch, the Auxiliary Dial or the Auxiliary Lever. For more information, see the ASSIGN Menu section on pages 33 ~ 38.Exponential Rate percentage values can be adjusted from Mild through Linear to Quick to allow you to set the most effective control response for your Model. For example, if your Model over-steers, reduce the Steering Exponential Rate percentage value and if your Model under-steers, Increase the Steering Exponential Rate percentage value.For another example, reduce the Throttle High Side Exponential Rate percentage value on a slippery track or with a Model that has a Higher-torque motor or engine, and Increase the Throttle High Side Exponential Rate percentage value on a high-grip track or with a Model that has a Lower-torque motor or engine.For the utmost in precision control, Exponential Rate percentage values can be adjusted separately for the Throttle High Side and the Throttle Brake Side. In addition, the Exponential Tweak Right and Tweak Left function allows you to balance Exponential for Right and Left Steering.

When a Positive or Negative Exponential percentage value is programmed, a Curve will be created from a fixed Neutral Point. This Curve will be equal on both sides, except for the Throttle channel. For more information, see the notation below.1) From within the CURVE menu, scroll UP or DOWN to highlight RATE > 0%.2) Press the ENTER key, then scroll UP or DOWN to Increase or Decrease the Rate percentage value. Using a Negative Rate percentage value will Soften the control feel around Neutral and using a Positive Rate percentage value will Heighten the control feel around Neutral.RATE setting range is -100% (Mild) to 100% (Quick). The default setting is 0% (Linear).You are able to adjust the Rate percentage value for the Throttle High Side and the Throttle Brake Side separately. In addition, you can even program Exponential for one Side and ARC or Point Curve for the other Side.Changing the Steering Tweak Right and Tweak Left Values:The Tweak function allows you to make small Exponential adjustments to the Right and/or Left sides of the Steering channel Neutral Point to fine-tune the balance between the two sides. Tweak value adjustments are effective whether you program a Negative or a Positive Rate value, or even program a Linear Rate value (0).1) From within the CURVE menu, scroll UP or DOWN to highlight the desired Tweak value, either TWEAK L or TWEAK R.2) Press the ENTER key, then scroll UP or DOWN to Increase or Decrease the Tweak value. Using a Negative Tweak value will Soften the control feel that side of Neutral and using a Positive Rate percentage value will Heighten the control feel around that side of Neutral.3) Press the ENTER key, then repeat steps 1 and 2 to change the other Tweak value, if desired.TWEAK L and TWEAK R setting range is -20 (Mild) to 20 (Quick). The default setting for both Tweak values is 0 (Linear).

Using a Lower Negative value allows for smoother control. Using a Higher Positive value may result in more 'twitchy' control response.The Adjustable Rate Control function works like the Exponential function, except that the Adjustable Rate Control function features the added benefit of being able to move the Neutral Point, whereas the Exponential function Neutral Point is fixed. In addition, the ARC Curve is more Linear than the Exponential Curve.Adjustable Rate Control Programming Values can be changed while you're driving by Assigning these functions to a Trim Switch, the Auxiliary Dial or the Auxiliary Lever. For more information, see the ASSIGN Menu section on pages 33 ~ 38. ARC Rate percentage values can be adjusted from Mild through Linear to Quick to allow you to set the most effective control response for your Model. For example, if your Model over-steers, reduce the Steering ARC Rate percentage value and if your Model under-steers, Increase the Steering ARC Rate percentage value.For another example, reduce the Throttle High Side ARC Rate percentage value on a slippery track or with a Model that has a Higher-torque motor or engine, and Increase the Throttle High Side ARC Rate percentage value on a high-grip track or with a Model that has a Lower-torque motor or engine.For the utmost in precision control, ARC Point and Rate values can be adjusted separately for the Throttle High Side and the Throttle Brake Side.

In addition, you can even program ARC for one Side and Exponential or Point Curve for the other Side.Changing the Rate Percentage Value:The Rate percentage value determines the amount and type of ARC, either Quick, Mild or Linear (see diagram on the previous page). When a Positive or Negative ARC percentage value is programmed, a Linear Curve will be created from the Neutral Point. 1) From within the CURVE menu, scroll UP or DOWN to highlight RATE > 0%.2) Press the ENTER key, then scroll UP or DOWN to Increase or Decrease the Rate percentage value. Using a Negative Rate percentage value will Soften the control feel around the Neutral Point and using a Positive Rate percentage value will Heighten the control feel around the Neutral Point.RATE setting range is -100% (Mild) to 100% (Quick). The default setting is 0% (Linear).Point Curve ProgrammingThe Point Curve function allows you to vary the amount of servo travel in relation to the movement of the Steering Wheel and Throttle Trigger (or in some cases, the Auxiliary Dial and/or the Auxiliary Lever) at different Points along the entire range of control travel to change the way those functions react to control movement. Nine programmable Points allow you to create your own custom Point Curve to suit any situation.The Point Curve function works like the Exponential and ARC functions, except that the Point Curve function allows you to program up to 9 different Points along the entire range of control travel to suit whatever setup or situation is required. For example, you can customize the Point Curve to include Mild or Quick Points along the same Curve, or you can create a smooth Point Curve or a more Linear Point Curve.Point Curve percentage values can be adjusted from Mild through Linear to Quick to allow you to set the most effective control response for your Model. For example, if your Model over-steers, reduce the Point Curve percentage values and if your Model under-steers, Increase the Point Curve percentage values.For another example, reduce the Throttle High Side Point Curve percentage values on a slippery track or with a Model that has a Higher-torque motor or engine, and Increase the Throttle High Side Point Curve percentage values on a high-grip track or with a Model that has a Lower-torque motor or engine.For the utmost in precision control, Channel Curves can be programmed separately for the Throttle High Side and the Throttle Brake Side.

Pressing and HOLDING the switch will turn Anti-Lock Braking ON and releasing the switch will turn Anti-Lock Braking OFF.Anti-Lock Braking Programming Values can be changed while you're driving by Assigning these functions to a Trim Switch, the Auxiliary Dial or the Auxiliary Lever. For more information, see the ASSIGN Menu section on pages 33 ~ 38.Changing the Stroke Percentage Value:The Stroke percentage value determines the amount of Brake that's applied automatically when the Anti-Lock Braking function is turned ON.A Stroke percentage value of 1% or greater must be programmed for the Anti-Lock Braking function to be turned ON. If a Stroke value of OFF is chosen, the Anti-Lock Braking function cannot be turned ON.1) From within the RACING menu, scroll UP or DOWN to highlight the ALB menu.STROKE setting range is OFF to 100%. The default setting is OFF.2) Press the ENTER key to open the ALB menu. STROKE > OFF will be highlighted.3) Press the ENTER key, then scroll UP or DOWN to choose the desired Stroke percentage value. Increasing the Stroke percentage value will Increase Throttle servo travel in the Brake direction and Decreasing the Stroke percentage value will Decrease Throttle servo travel in the Brake direction.Throttle NeutralPointLagReleaseHoldStrokeThe Anti-Lock Braking function makes it possible to achieve stable Braking even on a slippery surface. With stable Braking, your Model is better able to trace an exact line under Braking. When the Anti-Lock Braking function is turned ON, the Throttle servo will pulse when you apply Brake. Different Anti-Lock Braking options can be programmed, including how quickly the Brake pulsates, the Point at which the Anti-Lock Braking function Starts and more.The Anti-Lock Braking function is primarily used on gasoline- or glow-powered Models that feature a Throttle servo. It can be used on an electric Model that uses an Electronic Speed Control, however, if your Electronic Speed Control features a reverse function, the Anti-Lock Braking function will not operate properly.The Anti-Lock Braking function operates only when the Throttle Trigger is moved from Neutral to the Brake Side. Set the hardest Braking you can obtain from your Model by carefully setting the Anti-Lock Braking function Right before the tires fully lock up but do not slip and lose traction. Be aware that using the Anti-Lock Brake function will never result in your Model losing traction under Braking. It only improves Braking under less than ideal conditions. With ABS ON With ABS OFFThe diagram at Right illustrates the relationship between the Point, Lag, Release, Hold and Stroke functions, all of which can be programmed separately to suit your specific Car Type, track conditions and Anti-Lock Braking behavior.If desired, you can change the behavior of the switch from PUSH (default) to TOGGLE. For more information, see the Changing the Switch Mode section on page 34.

85M12S 2.4GHZ FH4T RADIO CONTROL SYSTEM USER'S GUIDETRALB MENU {ANTI-LOCK BRAKING}RACINGChanging the Point Percentage Value:The Point percentage value determines the position along the length of Brake Side servo travel that the Anti-Lock Braking function Activates at when turned ON. For example, if set to 80%, you will have Normal Braking from the Throttle Neutral Point to 79% of servo travel. At 80% of servo travel and beyond, the Anti-Lock Braking function will Activate when turned ON.POINT setting range is 5% to 100%. The default setting is 80%.1) From within the ALB menu, scroll UP or DOWN to highlight POINT > 80%.2) Press the ENTER key, then scroll UP or DOWN to choose the desired Point percentage value. Increasing the Point percentage value will cause the Anti-Lock Braking function to Activate later and Decreasing the Point percentage value will cause the Anti-Lock Braking function to Activate sooner.Changing the Release and Hold Values:The Release and Hold values determine the speed at which the Brake pulsates. By changing the Release and Hold values, you can make the Brake pulsate Faster or Slower. The Release value determines how quickly the Brake moves from the Point setting to the Stroke setting and the Hold value determines how quickly the Brake moves from the Stroke setting back to the Point setting.We recommend using equal Release and Hold values, although different values can be used to fine-tune how the Brake pulsates. Using Lower values make the Brake pulsate Faster and using Higher values make the Brake pulsate Slower.RELEASE setting range is 0.01s to 1.00s. The default setting is 0.03s.1) From within the ALB menu, scroll UP or DOWN to highlight RELEASE > 0.03s.2) Press the ENTER key, then scroll UP or DOWN to choose the desired Release value in Seconds. Increasing the Release value will cause the Brake to move from the Point setting to the Stroke setting Slower and Decreasing the Release value will cause the Brake to move from the Point setting to the Stroke setting Faster.HOLD setting range is 0.01s to 1.00s. The default setting is 0.03s.3) From within the ALB menu, scroll UP or DOWN to highlight HOLD > 0.03s.4) Press the ENTER key, then scroll UP or DOWN to choose the desired Hold value in Seconds. Increasing the Hold value will cause the Brake to move from the Stroke setting back to the Point setting Slower and Decreasing the Hold value will cause the Brake to move from the Stroke setting back to the Point setting Faster.Changing the Lag Value:The Lag value determines the amount of Delay before the Anti-Lock Braking function Activates after reaching the Point setting.LAG setting range is 0.00s to 1.00s. The default setting is 0.00s.1) From within the ALB menu, scroll UP or DOWN to highlight LAG > 0.00s.2) Press the ENTER key, then scroll UP or DOWN to choose the desired Lag value in Seconds. Increasing the Lag value increases the Delay time to Activate the Anti-Lock Braking function after reaching the Point setting and Decreasing the Lag value decreases the Delay time to Activate the Anti-Lock Braking function after reaching the Point setting.OFFSET MENU {THROTTLE OFFSET}RACINGThe Throttle Offset function allows you to shift the Neutral Point of the Throttle servo to a fixed position, either toward the High Side or the Brake Side, while still allowing you full control of the Throttle. For example, if you're driving a glow- or gas-powered Model, you can use the Throttle Offset function to raise the engine idle for starting or you can program the Throttle Offset function to Increase the engine to a steady idle while you're refueling during a race. If your Model features a separate Brake servo, a Brake Lock function is featured that can be programmed to apply Brake while the Throttle is increased to keep your Model from moving.The Throttle Offset function shifts the Neutral Point of the Throttle servo without affecting the High Side or Brake Side End Points. This allows you to have full control over the Throttle even when the Throttle Offset function is turned ON.

The default setting is 0%.Changing the Brake Lock Percentage Value:When Car Type II, III, IV,VI or VII is Selected, the Brake Lock function can be programmed to apply Brake to keep your Model from moving while the Throttle Offset Position is increased. If your Car Type features two separate Brake channels, such as Car Type IV, the Brake Lock function percentage value will affect both Brake channels equally.1) From within the OFFSET menu, scroll UP or DOWN to highlight BR-LOCK > OFF.2) Press the ENTER key, then scroll UP or DOWN to choose the desired Brake Lock percentage value. The Brake Lock percentage value determines the position your separate Brake servo (or servos) will shift to when the Throttle Offset function is turned ON.BR-LOCK setting range is OFF and 0% to 100%. The default setting is OFF.OFFSET MENU {THROTTLE OFFSET}RACINGThrottle Offset Programming Values can be changed while you're driving by Assigning these functions to a Trim Switch, the Auxiliary Dial or the Auxiliary Lever. For more information, see the ASSIGN Menu section on pages 33 ~ 38.In the default configuration, Push-Button Switch Sw1 turns the Throttle Offset function ON and OFF.

87M12S 2.4GHZ FH4T RADIO CONTROL SYSTEM USER'S GUIDETRBR-MIX MENU {DUAL BRAKE MIXING}RACINGThe Brake Mixing function allows you change the Brake Bias between the Front and Rear Brakes and is used primarily with 1:5th scale gas-powered Models that use separate Brake servos, although one of the separate Brake servos can be the Brake Side of the Throttle servo, such as when Car Type III is Selected. The Brake Mixing function slows the transit speed of one or both Brake servos, which not only allows to slow down the Braking action, but also allows you to set a Delay between them, which results in you being able to change the Brake Bias.Brake Delay Programming Values can be changed while you're driving by Assigning the these functions to a Trim Switch or the Auxiliary Dial. For more information, see the ASSIGN Menu section on pages 33 ~ 38.The Brake Mixing function is available only when either Car Type III, IV or VII is Selected. Changing the Brake Delay Percentage Value:1) From within the RACING menu, scroll UP or DOWN to highlight the BR-MIX menu.2) Press the ENTER key to open the BR-MIX menu. BR-DELAY > 0% will be highlighted.3) Scroll UP or DOWN to highlight the Brake Delay percentage value you would like to change, either BR-DELAY or BR2-DELAY.Which Brake Delay percentage value affects the Front or Rear Brake servo depends on how your Brake servos are plugged into the receiver and will vary.4) Press the ENTER key, then scroll UP or DOWN to choose the desired Brake Delay percentage value. Increasing the percentage value will slow the transit speed of that Brake servo.5) Press the ENTER key, then repeat steps 3 and 4 to change the other Brake Delay percentage value, if desired. The larger the difference between the two Brake Delay percentage values, the greater the Brake Bias.BR-DELAY and BR2-DELAY setting range is 0% to 100%. The default setting for both channels is 0%.Setting both Brake Delay percentage values to the same percentage value will result in both Brake servos moving at the same speed. This allows you slow down the Braking action if that is desired. Using different percentage values will result in Brake Bias. You may find that you will need to use a larger percentage value to make a noticeable difference in Brake Bias.TH-HLD MENU {THROTTLE HOLD}RACINGThe Throttle Hold function moves the Throttle servo to a fixed position, either toward the High Side or the Brake Side, and is used primarily with glow- or gas-powered Models. For example, if you're driving a glow- or gas-powered boat, you can use can the Throttle Hold function to stop your engine with only the press of a button. This feature is often referred to as 'Engine Cut'. Alternately, you can use the Throttle Hold function to Increase the engine to a steady idle while you're refueling during a race. This feature is often referred to as 'Idle Up'. If your Model features a separate Brake servo, a Brake ON/OFF function is featured that will allow you to lock out the Brake servo (ON) or allow you control of the Brake servo (OFF) while the Throttle Hold function is turned ON.The Throttle Hold function moves the Throttle servo to a fixed position, either toward the High Side or the Brake Side. When the Throttle Hold function is turned ON, you will NOT have control of the Throttle. If your Model has a separate Brake servo and you set the Brake ON/OFF function to OFF, you will still have control over your Model's Brake. To regain Throttle control, you must turn the Throttle Hold function OFF.HOLDNH B150% 150%High Side Brake Side0%WARNING: The Throttle Hold percentage value can be set Higher than your Throttle High Side and Throttle Brake Side End Points. To avoid damage to your Model, we don't suggest programming a Throttle Hold percentage value that exceeds your Throttle High Side or Throttle Brake Side End Points.

HOLD > 0% will be highlighted.3) Press the ENTER key, then scroll UP or DOWN to choose the desired Hold percentage value. The Hold percentage value determines the position the Throttle servo will move to when the Throttle Hold function is turned ON. Choosing a Positive Hold percentage value will move the Throttle servo toward the High Side and choosing a Negative Hold percentage value will move the Throttle Servo toward the Brake Side.HOLD setting range is 150% to -150%. The default setting is 0%.Turning the Throttle Hold Function ON and OFF:1) From within the TH-HLD menu, scroll UP or DOWN to highlight ACT/INH > INH.2) Press the ENTER key, then scroll UP or DOWN to choose the desired ACT/INH setting, either ACT (Active ON) or INH (Inhibited OFF).ACT/INH setting range is ACT and INH. The default setting is INH.We suggest Assigning the Throttle Hold function to a Push-Button Switch so that you can turn it ON and OFF without needing to access the TH-HLD menu. See the notation at the top of the page. In addition, ON and OFF behavior will differ based on the ACT/INH setting you choose. We recommend using the INH setting. With this setting, the Throttle Hold function will always be OFF until you turn it ON. If you choose ACT, the Throttle Hold function will always be ON until you turn it OFF.Changing the Brake Lock-Out Value:When Car Type II, III, IV,VI or VII is Selected, the Brake Lock-Out function can be programmed, which gives you the option to lock out the Brake servo(s) or retain control of the Brake servo(s). This gives you the option of controlling your separate Brake servo(s) to keep your Model from moving, even when your engine's idle Increases when the Throttle Hold function is turned ON. If your Car Type features two separate Brake channels, such as Car Type IV, the Brake Lock-Out function will affect both Brake channels equally.1) From within the TH-HLD menu, scroll UP or DOWN to highlight BR > ON.2) Press the ENTER key, then scroll UP or DOWN to choose the desired Brake value, either ON or OFF. When set to ON, your separate Brake servo(s) will be locked out along with the Throttle servo when the Throttle Hold function is turned ON.

The default setting is ON.Keep in mind that the Throttle Hold percentage value can be set Higher than your Throttle High Side and Throttle Brake Side End Points. To avoid damage to your Model, we don't suggest programming a Throttle Hold percentage value that exceeds your Throttle High Side or Throttle Brake Side End Points.

89M12S 2.4GHZ FH4T RADIO CONTROL SYSTEM USER'S GUIDETRThe Compensation Mixing function is used to create your own custom Mixes that allow you to control any number of desired functions in different combinations. For example, you can use the Compensation Mixing function to deploy an air-Brake when you apply Brake or raise a wing as you Increase Throttle. You could use the Compensation Mixing function to counter-act torque steer by applying a very slight amount of Steering in one direction when you Increase Throttle. The possibilities are nearly endless.Compensation Mixes are composed of a Master channel and a Slave channel. The Master channel always controls the Slave channel. Any of the four channels can be programmed as a Master or a Slave. The same channel can even be programmed as both a Master and a Slave. Two Rate percentage values can be programmed to determine the direction and amount of travel that the Slave channel servo moves in relation to the Master channel servo. In addition, an Offset function is featured that allows you to shift the Neutral Point of the Slave channel servo to center the Slave channel servo or to shift the Slave channel servo's Neutral Point to change the starting point of your Mix. Two Compensation Mixers are available, and each can be turned ON separately or both can be turned ON at the same time. A graph is featured to help visualize the Compensation Mixing changes you make.Compensation Mixing Programming Values can be changed while you're driving by Assigning these functions to a Trim Switch, the Auxiliary Dial or the Auxiliary Lever. For more information, see the ASSIGN Menu section on pages 33 ~ 38.This section covers both the Compensation Mixing 1 and Compensation Mixing 2 menus, since programming each of them is exactly the same. Choose either the C-MIX1 or the C-MIX2 menu depending on which of the two Compensation Mixers you want to program.The Compensation Mixing Rate 1 and Rate 2 percentage values determine whether the Compensation Mixer(s) are Active (turned ON) or Inhibited (turned OFF). When no Rate percentage values are programmed, the Compensation Mixer(s) will be Inhibited and when a Rate percentage value is programmed, the Compensation Mixer(s) will become Active. To turn the Compensation Mixer(s) ON and OFF while you're driving, you will need to program the Compensation Mixer(s) with a Rate value to one Racing Mode (turned ON), then switch to a Racing Mode without any Compensation Mixer Rate values programmed (turned OFF).C-MIX1 AND C-MIX2 MENU {COMPENSATION MIXING 1 AND COMPENSATION MIXING 2}RACINGSteeringWheel100 100100 10010 10SteeringServoThrottleServoSteeringOperation CH2MasterThrottleOperationCalculationCalculationServoOutputServoOutput CH1# MasterIn the example above, Compensation Mixing 1 is programmed as follows: MASTER > ST, SLAVE > TH, RATE1 > 10%, RATE2 > 10% and OFFSET > 0. When you move the Steering Wheel 100% in each direction, the Steering servo will travel 100% in each direction and at the same time, the Throttle servo will travel 10% in each direction.Compensation Mixing Rate percentage values are a Ratio of Slave channel servo travel to Master channel servo travel. For example, if both Rate percentage values are set to 10%, the Throttle servo will travel 1:10th the amount as the Steering servo travels in both directions. Compensation Mixes are Linear throughout the entire range of travel. If a Rate value of 0% is chosen, the Slave servo will not move in that direction.Compensation Mixing 1 Steering to Throttle Mix Example:Available channels vary based on the Car Type currently chosen.

Use a Positive or Negative percentage value to change the amount and direction of Slave channel servo travel. The Right side of the graph indicates Rate 1 percentage values and the Left side of the graph indicates Rate 2 percentage values.1) From within the C-MIX1 menu, scroll UP or DOWN to highlight either RATE1 > 0% or RATE2 > 0%.2) Press the ENTER key, then scroll UP or DOWN to choose the desired Rate 1 or Rate 2 percentage value.RATE1 and RATE2 setting range is -150% to 150% . The default setting for both Rate percentage values is 0%.WARNING: The Rate percentage values can be set Higher than your Slave channel servo End Points (up to 150% in either direction). To avoid damage to your Model, we don't suggest programming Rate percentage values that exceed your Slave channel servo End Points.Changing the Channel Offset Value:The Offset function allows you to shift the Neutral Point of the Slave channel servo to compensate for any Master channel servo Trim or to change the starting point of your Mix.1) With the Master channel control centered, check the Master Travel Indicator at the bottom of the graph to see if any Master channel Trim is displayed.2) From within the C-MIX1 menu, scroll UP or DOWN to highlight OFFSET > 0.3) Press the ENTER key, then scroll UP or DOWN to choose the desired Slave channel Offset value. Increase or Decrease the Offset value to move the vertical axis in the desired direction.OFFSET setting range is -150 to 150 . The default setting is 0%.Following the example in the diagram at Right, set the Rate 1 percentage value to 0% and the Rate 2 percentage value to -50%, then set the Offset value to -100. The full range of Mixing travel can now be adjusted in one direction when turning the Auxiliary Dial counter-clockwise.This same technique can also be used if you're using the Auxiliary Lever to control either Auxiliary 1 or Auxiliary 2.When the Auxiliary Dial is programmed to control Auxiliary 1 or Auxiliary 2 and you choose AUX1 or AUX 2 (or #AUX1 or #AUX2) to be the Master channel, by setting the Offset value to 100 or -100, the Auxiliary Dial can control the full range of Mixing travel in one direction, instead of half the Mixing travel in one direction and half the Mixing travel in the other direction. This is useful if you want the full range of Mixing travel in only one direction.Setting the Offset value to a value greater than -100 or 100 will shift the Neutral Point of the Slave channel servo beyond the operation range of the Auxiliary Dial and is not recommended.0MAXAuxiliaryDial

92M12S 2.4GHZ FH4T RADIO CONTROL SYSTEM USER'S GUIDEACKER MENU {ACKERMAN ANGLE ADJUSTMENT}RACINGThe Ackerman function allows you to change the Steering angle of the Front tires independently to prevent the tires from slipping during turns. Being able to change the Ackerman Angle can help improve your Model's high-speed cornering and improve tire wear. In general, your Model will corner better if the inner tire turns in at a sharper angle than the outer tire. The Ackerman function allows you reduce the turn-in angle of the outer tire, which increases the turn-in angle of the inner tire relative to it.Ackerman Programming Values can be changed while you're driving by Assigning these functions to a Trim Switch, the Auxiliary Dial or the Auxiliary Lever. For more information, see the ASSIGN Menu section on pages 33 ~ 38.The Ackerman function is available only when either Car Type V, VI or VII is Selected. Changing the Ackerman Angle Percentage Values:1) From within the RACING menu, scroll UP or DOWN to highlight the ACKER menu.2) Press the ENTER key to open the ACKER menu. LEFT-ST L > 100% will be highlighted.3) Scroll UP or DOWN to highlight the Ackerman Angle percentage value you would like change. Choose from either LEFT-ST (Left Steering) Left or Right, or RIGHT-ST (Right Steering) Left or Right.4) Press the ENTER key, then scroll UP or DOWN to choose the desired Ackerman Angle percentage value. Reducing the Ackerman Angle percentage value will reduce the amount of control throw in that the direction for that specific servo.5) Press the ENTER key, then repeat steps 3 and 4 to change any other desired Ackerman Angle percentage values.In general, you want the inner tire to turn in more than the outer tire when turning both Right and Left (unless you're running on an oval track). In order to achieve this, you will need to reduce the control throw of the outer tire in both the Right and Left directions by reducing those Ackerman Angle percentage values. The percentage values you will need to change will vary depending on several factors, so you'll need to experiment to find the ones you need to reduce to achieve the desired results.LEFT-ST L and R and RIGHT-ST L and R setting range is 0% to 100%. The default setting for both channels is 100%.R-DLY MENU {RACING MODE DELAY}RACINGThe Racing Mode Delay function allows you to program a Delay for each of the four channels to help prevent drastic changes in channel function settings when switching between Racing Modes. For example, you might have one Dual Rate setting for Racing Mode 1 and a different Dual Rate setting for Racing Mode 2. The Racing Mode Delay function allows you to program a Delay in the Steering channel so that the transition to the different Dual Rates when you switch back and forth between Racing Modes is smooth and less noticeable.Racing Mode Delay Programming Values can be changed while you're driving by Assigning these functions to a Trim Switch, the Auxiliary Dial or the Auxiliary Lever.

96M12S 2.4GHZ FH4T RADIO CONTROL SYSTEM USER'S GUIDETELEMETRY CONNECTIONS AND MOUNTING REFERENCEOverview:The RX-461 and RX-462 receivers each feature two Temperature Sensor Inputs and one RPM Sensor Input, in addition to the Voltage Sensor built into the receiver. Temperature and RPM Sensors can be installed into your Model to give you Temperature and RPM or Speed feedback in real-time displayed on the transmitter's TELEMETRY screen.The range of the Telemetry System is approximately 260 feet (80 meters), although the range can vary based on many environmental factors. Use the Telemetry Signal Indicator to determine the quality of the Telemetry Signal.When used with an Airtronics 2.4GHz FH4T Telemetry-capable surface receiver, such as the RX-461 or RX-462, and up to two Temperature Sensors and an RPM Sensor (all available separately), Telemetry Data, such as RPM or Speed, Temperature, and Receiver Voltage can be viewed on the M12S transmitter's TELEMETRY screen.This section details connecting the RPM and Temperature Sensors to the RX-461 and/or RX-462 receiver and how to mount those Sensors into your Model. For more information about the specifics of either receiver, refer to the User's Guide included with your receiver.For more information about viewing Telemetry Data on the TELEMETRY screen, see the TELEMETRY Screen Overview section on pages 22 ~ 23. For more information about choosing Telemetry options, see the LOG SETUP Menu section on pages 48 ~ 56.Plugging the Telemetry Sensors into the Receiver:1) Carefully pry up and remove the plastic cover from over the Telemetry Sensor Input Ports on the receiver.2) Plug the Telemetry Sensor(s) into their respective Input Ports in the receiver. The Temperature Sensor can be plugged into either the TEMP 1 or the TEMP 2 Input Port and the RPM Sensor is plugged into the RPM Input Port. The Sensor Plugs are indexed so they can be plugged in only one way.Make sure to push the Sensor Plugs firmly in place to ensure a good connection. When routing Sensor Wires inside your Model, be careful that they cannot come into contact with any moving parts. The Sensor Wires should be securely mounted and protected against damage. In addition, install the dust covers included with your receiver to prevent dirt and debris from getting into any unused Input Ports.1) Mount the RPM Sensor to an aluminum or ABS angled bracket, then mount the bracket to your Model, making sure that it's held securely in place. For optimal operation, the Sensor Pickup should be positioned approximately 1mm away from the rotating part (flywheel, spur gear, pinion gear etc.)2) Cut one of the two reflective decals included with the RPM Sensor into an ~2mm diameter and apply it to the rotating part, so that as the part rotates, the reflective decal passes in Front of the Sensor Pickup. If the rotating part is metallic-colored (silver, aluminum, chrome, etc.), use the Black reflective decal and if the rotating part is dark-colored (black, blue or another dark color), use the White reflective decal.When installed, it's important that the Sensor Pickup face the rotating part and that the Black or White reflective decal is positioned so that it passes in Front of the Sensor Pickup. It's also important that the reflective decal contrasts with the rotating part it's applied to and that the Sensor Pickup is mounted approximately 1mm away from the rotating part.After installing the RPM Sensor and connecting it to your receiver, the RPM Sensor must be calibrated. For more information, see the RPM and Speed Telemetry Data Display Options section on pages 48 ~ 50.Mounting the RPM Sensor:The RPM Sensor uses infrared technology to record RPM data from a rotating part, such as a flywheel or a spur gear. One Black and one White reflective decal is included that is attached to the rotating part so the Sensor Pickup can 'see' it.Sensor PickupInput PlugReflective DecalAngled BracketRPM SensorSensor PickupSpur Gear or Other Rotating Part~1mmSensor Pickup

97M12S 2.4GHZ FH4T RADIO CONTROL SYSTEM USER'S GUIDETRMounting the Temperature Sensor:1) Secure the Sensor End directly against the part of your engine, motor, battery or other object you want to monitor temperature readings from, using either a nylon cable tie or high-temperature clear tape. For example, to monitor the cylinder head temperature of your glow-powered Model, the best place to secure the Sensor End is where the bottom of the cylinder head meets the top of the engine case. The Sensor End can be held in place using a nylon cable tie wrapped around your engine. To monitor the temperature of your battery pack or electric motor, high-temperature clear tape can be used to secure the Sensor End to the exact spot you want to monitor.Sensor EndInput PlugAttach withHigh-Temperature Clear TapeTELEMETRY CONNECTIONS AND MOUNTING REFERENCETROUBLESHOOTING GUIDE REFERENCEThis troubleshooting guide can help you diagnose and solve some of the more common problems that you may encounter with your radio control system.If you cannot solve the problem using this troubleshooting guide, please contact Airtronics Customer Service using the information in the Service and Support section on page 3.Transmitter does not turn ONTransmitter will not bind to receiverReceiver won't power ONAudible alarm beeps continuouslyOne or more LEDs flashingNo key-press, Trim, alarm or alert soundsServo movement is slowServo does not move when using Trim SwitchTransmitter batteries installed incorrectlyBattery tray not plugged inTransmitter batteries are deadDamage caused by using incorrect charger or reverse polarityModulation Type incorrect Too much time elapsed after pressing receiver Bind Button Attempting to Bind incompatible receiverUsing Electronic Speed control (ESC)Receiver batteries are deadUsing incorrect Binding procedureReceiver batteries are deadReceiver batteries not installed correctlyLoose switch connectionLow transmitter battery voltageTransmitter left ON 10 minutes or more without control inputTransmitter battery voltage too highIndicates transmitter status Audible tones are MutedLow receiver battery voltageControl linkages bindingUsing a negative Servo Speed valueTrim is outside of operational rangePROBLEMReinstall batteries, observing correct polarityPlug in battery trayReplace or recharge transmitter batteriesContact Airtronics Customer ServiceChange Modulation Type to match receiverQuickly press ENTER key in BIND menu after releasing receiver Bind ButtonUse only Airtronics 2.4GHz FH2, FH3, FH4 or FH4T surface receiversDisconnect ESC and use dry cell battery for Binding procedure, then reconnect ESC after BindingReplace or recharge receiver batteriesFollow Binding procedure carefullyReplace or recharge receiver batteries Reinstall receiver batteries, observing correct polarityDouble-check all connections including switchReplace or recharge transmitter batteriesMove Steering Wheel or Throttle Trigger, or press any key to clear alarm and continue operationUse transmitter battery whose voltage is 9.6 volts or less when fully chargedFor more information, see LED Condition Indicators table on page 10.

Each Push-Button Switch is programmable and will perform a different function depending on what function is Assigned to it. Sw2 is a Rocker Switch that can be pressed from either the Front or the Back.Racing Mode: Provides you with five separate Racing Modes that you can switch between while you're driving. Racing Mode Indicator: Indicates on the LCD screen which Racing Mode (R1 ~ R5) is Active.Racing Mode LED: Displays which Racing Mode is currently Active. The color of the LED will vary depending on which of the five Racing Modes is Active. When extinguished, Racing Mode is Inhibited.Receiver Battery Voltage Fail Safe: Used to set a custom voltage that the Receiver Battery Fail Safe function will Activate at to alert you when your receiver battery needs recharging. This ensures that your servos continued to operate optimally at all times.Receiver Voltage Display: Displays on the TELEMETRY screen the current Voltage of the receiver battery. The tick mark indicates the current Voltage relative to the programmed Maximum Voltage value.Release Setting: Determines how quickly the Brake moves from Neutral to the percentage value determined by the Stroke setting when the Anti-Lock Braking function is Active.RF Indicator: Indicates whether the transmitter is sending an RF (Radio Frequency) signal or not.RPM: Revolutions Per Minute. RPM/Speed Gauge: Displays on the TELEMETRY screen the current RPM or speed in MPH or KM/H in graphical format. The needle indicates the current RPM or Speed relative to the programmed Maximum RPM or Speed value.Safety Link: Allows to program a unique code to each receiver/Model pair, preventing the transmitter from controlling a Model that it's not currently programmed for. This helps prevent a runaway Model should you accidentally choose the wrong Programming Data for the intended Model.Select Switch: Used along with the Push-Button Rotary Dial and the BACK key to facilitate transmitter programming. Use the SELECT switch to scroll through the STATUS screen's main menus, scroll through the TELEMETRY pages and make selections in many of the Programming Menus.Servo Monitor: Displays the output levels of the four channels in bar graph form, allowing you to monitor servo operation in a virtual manner. Servo Reversing: Used to electronically switch the direction of servo travel. Servo Speed: Used to slow down the transit speed of the servos. Servo transit speed can be slowed in both the Forward and the Return to Neutral directions.SHR Servo Mode: When used with Digital servos, this will increase the servo's response time, even above the manufacturer's stated specification. Do not use with Analog servos!SSR Servo Mode: When used with Airtronics SRG Digital servos, this will provide the fastest response time. This results in the ultimate feel and response, making you feel more in control of your Model than ever. Use only with Airtronics SRG Digital servos!Status Screen: Displays information about the transmitter and is the base from which you access other Programming Menus.Steering Output Display: Displays on the TELEMETRY screen the current position of the Steering channel as a percentage of Steering Wheel travel.Steering Spring Tension Adjustment Screw: Used to adjust the spring tension of the Steering Wheel to best suit the feel of the user.Steering Wheel: Proportionally operates the Model's Right and Left Steering control. The Steering Wheel features a foam grip for increased comfort, control and feel. The Steering Wheel's position, angle and spring tension can all be adjusted.Step Value: A preset amount that the servo will travel when a Trim Switch is pressed once. The Step value can be adjusted so that the servo either moves more or moves less when a Trim Switch is pressed.
