490478 2.4GHZ FH4T RADIO SYSTEM USER'S GUIDETRTRTR2.4GHZ FREQUENCY BAND PRECAUTIONS GENERAL• The 2.4GHz frequency band may be used by other devices, or other devices in the immediate area may cause interferenceon the same frequency band. Always before use, conduct a bench test to ensure that the servos operate properly. Also,conduct checks with the transmitter as distant as possible from your Model.• The response speed of the receiver can be affected if used where multiple 2.4GHz transmitters are being used, therefore,carefully check the area before use. If response seems slow during use, stop your Model immediately and discontinue use.• If the 2.4GHz frequency band is saturated (too many transmitters turned ON at once), as a safety precaution, the transmitterand receiver may not Bind. This ensures that your radio control system does not get hit by interference. Once the frequencieshave been cleared, or the saturation level has dropped, your transmitter and receiver should Bind without any problems.TRANSMITTER PRECAUTIONS GENERAL• To prevent possible damage to your servos or a runaway model, turn the transmitter ON first,then turn the receiver ON. After running your model, turn the receiver OFF first, then turn thetransmitter OFF.• Before use, double-check that the transmitter and receiver batteries have sufficientpower.• The transmitter antenna is mounted internally and is located in the vertical back portion of the carrying handle.Do NOT cover the carrying handle in any way during use! Doing so can block the RF signal, resulting in loss ofcontrol of your model.• During use, hold the transmitter so that its orientated as close to vertical as possible at all times. This provides the best RFsignal between the transmitter and the receiver. Try not to ever 'follow' your model with the transmitter,as this can result in a weakened RF signal.• Do not expose the transmitter or any other components to excessive heat,moisture, fuel, exhaust residue, etc.• If the outer case becomes dirty, it can be cleaned with a soft dry cloth. If the outer case becomessoiled, it can be cleaned with a damp cloth and liquid detergent. Do not use any solvents to cleanRECEIVER PRECAUTIONS GENERAL• The antenna consists of a coaxial cable and a reception wire (the thin tip at the end of the coaxial cable). When you mountthe antenna, do not bend the reception wire. Reception performance decreases if the reception wire is bent.• The antenna is delicate, therefore, handle with care. Do not pull on the antenna with force. Donot cut or extend the antenna.• The coaxial cable (the thicker portion of the antenna) can be bent into gentle curves, however,do not bend the coaxial cable acutely, or repeatedly bend it, or the antenna core can be damaged.• The antenna should be installed into a vertical plastic tube per your particular model's assembly instructions. Keep thereceiver antenna as far away from the motor, battery and ESC as possible.• There is a danger of runaway operation if connectors shake loose during use. Make sure that the receiver, servo(s) andswitch connectors are securely fitted.• The receiver is susceptible to vibration, shock and moisture. Take appropriate measures to protect against vibration andmoisture. Failure to take appropriate measures could result in runaway operation or damage to the receiver. We suggestwrapping the receiver in shock-absorbing foam or securing it with double-sided foam tape when installing it into yourmodel.• When routing the antenna, avoid contact with any carbon or metal chassis components. Contact between metal or carbonparts can result in electrical noise, which can adversely effect receiver performance and possibly result in runaway operationand result in damage to your model.• With electric-powered models, be sure to fit any brushed motors with a noise suppression capacitor. Without a noise suppressioncapacitor, excessive electrical noise generation can cause runaway operation and result in damage to your model.the outer case. Solvents will damage the finish.TELEMETRY SUPPORT INFORMATION GENERAL• Full telemetry support requires the use of an Airtronics 2.4GHz FH4T telemetry-capable surface receiver, such as the RX-461or RX-462, along with Airtronics Temperature and RPM Sensors (available separately). The included RX-472 receiver cansend Telemetry Data for the voltage of the receiver battery pack only, unless used with the Airtronics Super Vortex ZERO ESC.• Full Telemetry support is provided when used with an Airtronics Super Vortex ZERO ESC (available separately) plugged intothe BATT/SSL port of the included RX-472 receiver.• The range of the Telemetry System is approximately 260 feet (80 meters), although the range can vary based on manyenvironmental factors.

11TRTRTR90478 2.4GHZ FH4T RADIO SYSTEM USER'S GUIDEGENERALTRANSMITTER BATTERY OPTIONS GENERALThe 90478 transmitter's Operating Voltage Range is 4.0 to 9.6 volts. This allows you to use several different battery options (not included), depending on your preference.Alkaline - In the default configuration, the transmitter is designed to be powered using four 'AA' Alkaline batteries. This results in a transmitter that is lightweight and well-balanced for unmatched comfort.NiCd/NiMH - Rechargeable NiCd or NiMH batteries of desired capacity can be used in place of the Alkaline batteries. Using rechargeable NiCd or NiMH batteries is more convenient and cheaper in the long run. The Higher capacity batteries will also provide longer usage time than most Alkaline batteries. LiPo or LiFe - A 2 cell LiPo or LiFe battery pack can be used to power the transmitter. These battery packs are popular due to their light weight and high capacity for long usage time between charges.Transmitter power output, range and speed are the same, regardless of the battery type used. If using a LiPo or LiFe battery pack, please read the Warnings if Using a LiPo or LiFe Battery Pack section below.ALKALINE BATTERY INSTALLATION GENERAL3) Slide the battery cover back onto the transmitter and push it firmly until it 'clicks' closed.When installing the batteries, remove the battery holder and double-check that the battery holder is plugged in. If it isn't, plug the connector on the battery holder into the matching connector in the transmitter. 1) Remove the battery cover from the bottom of the transmitter by pushing firmly on the battery cover in the direction of the arrow.2) Install four fresh 'AA' Alkaline batteries into thebattery holder, making sure that the polarity iscorrect. The direction that each battery should beinstalled is molded into the bottom of the batteryholder (+ Positive and - Negative).The 90478 transmitter features a Charging Jack that can be used with the Airtronics 95034 Dual Output charger (available separately) to charge the optional NiCd or NiMH batteries. This allows you to charge these batteries without removing them from the transmitter. A Charging Jack is located on the Left side of the transmitter. For more information, see the Transmitter Overview Diagrams section on pages 6 and 7.WARNING: Do NOT attempt to recharge Alkaline batteries. Only NiCd or NiMH batteries should be charged through the transmitter's Charging Jack, using only the Airtronics 95034 Dual Output charger or equivalent overnight/slow charger. Do NOT attempt to charge a LiPo or LiFe battery pack through the Charging Jack.Do NOT use the Charging Jack with a fast charger or a peak-detection charger, or the transmitter could be damaged!If you use a fast charger or a peak-detection charger to charge the transmitter batteries, the battery holder must be removed from the transmitter first. The circuitry within the transmitter will interfere with the peak-detection charger's normal operation, resulting in over-charging and damaging the batteries and possibly the transmitter itself. In addition, the higher charge rate common in many fast chargers can damage the transmitter's circuitry.Damage caused by fast-charging through the transmitter or using an incorrect battery type will not be covered under warranty!TRANSMITTER BATTERY CHARGING OPTIONS GENERAL• Use ONLY a 2 Cell LiPo or LiFe battery pack of desired capacity.•Do NOT charge your LiPo or LiFe battery pack through the Charging Jack.

This makes it possible to balance servo travel in both directions and set the maximum desired amount of servo travel. For example, on a gas-powered model, if you pull the throttle trigger and the carburetor does not open completely, you can increase the Throttle High End Point Adjustment so that the carburetor opens completely. Another example is with steering. If your model turns sharper to the right than to the left, you can increase the Steering Left End Point Adjustment to balance the steering.

Press the ENTER key, then scroll UP or DOWN to increase or decrease theAuxiliary Low End Point Adjustment percentage value. Increasing the percentagevalue will increase auxiliary servo travel in that direction and decreasing the percentage value will decrease auxiliary servo travel in that direction.The Exponential and Adjustable Rate Control (ARC) functions allow you to vary the amount of servo travel in relation to the movement of the steering wheel, throttle trigger and auxiliary lever near the Neutral positions to change the way those functions react to control movement.Decreasing the Exponential or Adjustable Rate Control percentage values will soften the control feel around Neutral and increasing the Exponential or Adjustable Rate Control percentage values 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.The Exponential and Adjustable Rate Control functions can be adjusted for the Steering channel, the Throttle channel (Throttle High and Throttle Brake), Auxiliary 1 Channel 3 and Auxiliary 2 Channel 4.

With stable braking, your model is better able to trace an exact line under braking. The Anti-Lock Braking function also enables you to set different braking characteristics depending on your particular model. Different Anti-Lock Braking function options can be custom programmed, including the 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.Adjusting the Stroke Percentage Value:The Stroke percentage value determines the amount of Brake that's applied automatically when the Anti-Lock Braking function Activates. When set to OFF, the Anti-Lock Braking function will not work. A percentage value of 1% or greater must be programmed for the Anti-Lock Braking function to operate.When the Anti-Lock Braking function is Active, LED 1 (Blue) will flash rapidly.05.SPEED (SERVO SPEED)PROGRAM06.ALB (ANTI-LOCK BRAKING)PROGRAMThe 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 Braking 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 OFFThrottle NeutralPointLagReleaseHoldStrokeThe 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.MT-4S User's Guide.indd 24 2015/10/27 14:38:54

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.1) From within the ALB menu, scroll DOWN to highlight POINT 80%. Press the ENTER key,then scroll UP or DOWN to increase or decrease the Point percentage value. Increasingthe Point percentage value will cause the Anti-Lock Braking function to Activate laterand decreasing the Point percentage value will cause the Anti-Lock Braking functionto Activate sooner.ALB POINT setting range is 5% to 100%. The default setting is 80%.Adjusting the Release and Hold Values:The Release and Hold values determine the speed at which the brake pulsates. By adjusting the Release and Hold values, you can make the brake pulsate faster or slower. The Release value determines how quickly the Brake moves from Neutral to the percentage value determined by the Stroke setting and the Hold value determines how quickly the Brake moves from the Stroke setting to Neutral.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.PROGRAM1) From the Top Screen, press the ENTER key to open the Programming Menu list.2) Scroll UP or DOWN to highlight the ALB menu, then press the ENTER key.

This allows you to quickly switch between the Dig and Burn functions and still have the ability to variably change the Power Distribution between the Front and Rear motors. To set thisup, change the Auxiliary Lever Function to AUX2, then change the TWEAK (H) value to +100 and the TWEAK (L) value to -100. Formore information, see the Key Assignments section on pages 53 through 58. In addition, Auxiliary 2 can be assigned to theRotary Dial or one of the four Trim Switches. The Motor on Axle Mixing function can be toggled OFF and ON by assigningAuxiliary 2 to one of the two Push-Button Switches. For more information, see the Key Assignments section on pages 53through 58.IMPORTANT: In the default configuration, the Rotary Dial Step value is set to 5. This allows you to adjust the Power Distribution in 5 percent increments. If you prefer to control the Dig and Burn functions as if they were assigned to an ON/OFF switch, change the DIAL Step value to 100. For more information, see the Key Assignments section on pages 53 through 58.The Auxiliary Mixing function allows you to Mix either Steering Channel 1 or Throttle Channel 2 to Auxiliary 2 Channel 4, while maintaining separate Sub-Trim, End Point Adjustments, Servo Reversing and other channel-specific settings. For example, if your monster truck features dual Front steering servos, instead of using a Y-Harness to join the two steering servos, you can use Steering Mixing to operate both steering servos together and still be able to make adjustments to each servo separately.In addition, if your model features a third-channel brake, you could use Throttle Mixing to control it along with the channel 2 brake.The Auxiliary Mixing Rate percentage value can be adjusted while you're driving using one of the four Trim Switches, the Rotary Dial or the Auxiliary Lever.
