RDS8000 Aircraft and Helicopter Setup pages
Thank you for selecting the Airtronics RDS8000 Radio System. In designing the RDS8000 we have
made every effort to provide you with a radio that will allow you to extract the maximum performance
from your powered aircraft, sailplane, or helicopter, while at the same time simplifying the task of
setting up and adjusting your model. These instructions are written in great detail to help you
understand all of the RDS8000 capabilities. Because of the many features of the RDS8000,
this manual is quite long. Don’t be intimidated! To actually use the system, you may only need to
read the INTRODUCTION section, the Common Functions section, and study the section that applies
to your type of aircraft. Each type of aircraft, i.e., fixed wing and helicopter has its own self-contained
section describing each applicable feature and its implementation. However, helicopter flyers may
find it advantageous to read all sections of the manual to become more acquainted with the operation
of the RDS8000 unit. Note that the labels for fixed wing switch functions are in red letters and
helicopter switch functions are in Blue letters.
Again, we appreciate your selection of an Airtronics Radio Control System and wish you many hours
of flying enjoyment.
2.4 GHz system
This radio controller operates in the 2.4 GHz band. The 2.4 GHz connection is determined by the
transmitter and receiver pair, therefore, unlike ordinary crystal systems, the aircraft can be flown
without frequency control.
Also, a separate 2.4 GHz receiver can be purchased and paired with the included 2.4 GHz
transmitter through a pairing operation.

ACADEMY OF MODEL AERONAUTICS
5161 East Memorial Drive
Muncie, Indiana 47302
The Academy of Model Aeronautics (AMA) is a national organization representing modelers in the United
States. We urge you to examine the benefits of membership, including liability protection in the event of certain
injuries. The Academy has adopted simple and sane rules which are especially pertinent for radio controlled
flight as the OFFICIAL AMA NATIONAL MODEL AIRCRAFT SAFETY CODE, which we have partially reprinted
below:
I will not fly my model aircraft in sanctioned events, airshows or model flying demonstrations until it has been
proven to be airworthy by having been previously, successfully flight tested.
I will not fly my model higher than approximately 400 feet within 3 miles of an airport without notifying the
airport operator. I will give the right-of-way and avoid flying in the proximity of full-scale aircraft. Where
necessary, an observer shall be utilized to supervise flying to avoid having models fly in the proximity of
full-scale aircraft. Where established, I will abide by the safety rules for the flying site I use, and I will not willfully
and deliberately fly my models in a careless, reckless and/or dangerous manner.
I will have completed a successful radio equipment ground range check before the first flight of a new or
repaired model.
I will not fly my model aircraft in the presence of spectators until I become a qualified flyer, unless assisted by
and experienced helper.
I will perform my initial turn after take off away from the pit or spectator areas, unless beyond my control.

The above diagram shows how to connect the components of your RDS8000 system together. At this point your
objective is to get the system operating on your workbench. Once connected you must then refer to the
corresponding diagram for your system, i.e., either AERO or HELI showing the transmitter control stick function.
NiCd BATTERY CHARGING INFORMATION:
In order to protect the charging circuit in your RDS8000 transmitter, a diode has been installed to protect it from
some of the high discharge rate “cycler's” on the market. We recommend that you charge the transmitter
battery (while installed) with the supplied ATX charger, Part # 95033Z.
Should you wish to “cycle” or discharge the transmitter battery, you must first remove it from the transmitter.
This allows you to bypass the protective diode.
The following two Airtronics service items will allow you to “cycle” your RDS8000 transmitter battery. See your
local dealer for these items.
(1) #99704 Transmitter Charging Plug with Cable for use with your cycling device (black wire w/white tracer is
positive.
(1) #97051 Transmitter Battery Cycling Adapter Cable.
Above items will also work with Airtronics Quasar, Radiant, Vanguard, VG Series and all RD Series transmitter
batteries.
AIRBORNE COMPONENTS
TRANSMITTER BATTERY REMOVAL
While your system's batteries are charging, you can familiarize yourself with the airborne portion of your radio.
The airborne portion of the radio refers to any components which are mounted in your plane or helicopter and
carried aloft when you fly. The airborne components consist of the receiver, which receives the signals from the
transmitter, decodes them, and relays the commands to the servos; the servos which are simply electronically
controlled motors used to move the surfaces of the plane; the NiCd battery pack which provides power for the
receiver and servos to operate; and the switch harness which allows you to turn the airborne package on and off.
The NiCd battery in your RDS8000 transmitter can easily be removed and replaced with a fully charged pack
to extend operating time.
Additional packs are sold separately as an accessory item under the Airtronics part number 95010 (600Mah),
95090 (700Mah) or 95052 (1100Mah) battery packs.
To remove the pack, push down on the two ears of the battery door located on the rear of the transmitter.
The door can then be removed and the NiCd battery pack can now be removed and unplugged. Reverse the
procedure to install a new pack.
CONNECTORS
Your RDS8000 unit is equipped with the newer universal AIRTRONICS “Z” connectors which are color coded blue,
and are electrically compatible with the receivers of other radio control system manufacturers. The connectors
are rugged but should be handled with care. Note that these connectors are not compatible with older
AIRTRONICS R/C equipment unless Adapter p/n 99399Z is used!

Positive
CAUTION:
Observe the correct polarity when plugging in the NiCd battery pack.
If incorrect, damage to the transmitter will occur!

THROTTLE HIGH WARNING
The RDS8000 has a built in warning feature that will not allow you to use the transmitter if the throttle stick is not
in the lowest position when you turn on the transmitter. If the throttle stick is not in the low position, when you
turn it on, you will hear a continuous beeping sound and the display will read TH-HI! Pull the throttle stick down
to the full low position. The normal menu will then be displayed and you can operate and/or program the
transmitter.
TRANSMITTER STICK LENGTH ADJUSTMENT
AUDIO LOW VOLTAGE ALARM
Your RDS8000 transmitter is equipped with an Audio Alarm which will sound whenever the transmitter batteries
drop below 9.5 volts during transmitter operation. If the alarm sounds while you are flying, land immediately
and don’t operate the transmitter until it has been charged for 12 hours. The transmitter should normally
operate 120 to 150 minutes before the alarm sounds. If the alarm sounds even after the batteries have been on
charge for the required time it indicates that there is a problem with either the battery pack or the transmitter,
and you should contact AIRTRONICS about service.
The sticks in your RDS8000 transmitter are adjustable in length and spring tension to allow you to tailor their feel
to your personal preference. To adjust stick length, hold Part B with your fingers and unscrew Part A
counterclockwise to loosen the two pieces. Now screw Part A in or out to the desired position and lock it in
place by screwing Part B against it. It is best to leave at least four threads inside Part A when screwed out to its
longest length for the best mechanical security. Do not over tighten when you screw the two parts together.

TRANSMITTER STICK TENSION ADJUSTMENT
Precautions on using the 2.4 GHz band
To adjust the spring tension of the transmitter sticks you need to remove the back of the transmitter case. First
remove the antenna and the NiCd battery pack from the transmitter. Now remove the eight screws that hold the
case back in place, four in the main case, two in the LCD back cover and two on the handle.
Once the screws are removed swing the back of the case away from the transmitter being careful of the trainer
plug wiring.
1. The 2.4 GHz band may be used by other devices, or other devices in the immediate area may cause
interference on the same band. Always before takeoff, conduct a bench test to make sure the servos operate
properly. Also, conduct checks with the transmitter as distant as possible from the aircraft. Safety is best
ensured by having an assistant carry the aircraft as far away as possible for checks.
2. Do not fly aircraft in the vicinity of areas in which wireless LANs are being used. Also, do not operate the
transmitter anywhere near cell phones or other devices that generate radio waves, etc. This can have
adverse effects such as shortening the coverage distance of the aircraft.
3. The response speed of the receiver can be affected if used where multiple 2.4 GHz radio controllers are
being used, therefore carefully check the area before takeoff. Also, if response seems slow while flying,
land immediately and stop flying.
4. Observe any applicable laws and regulations on fly zones when using the 2.4 GHz radio controller.
5. Unlike frequency bands used with earlier radio controllers, reception with this 2.4 GHz radio controller is
adversely affected by large obstructions and concrete or steel structures between the aircraft and
transmitter. Also, wire mesh and similar barriers can adversely affect operation. Keep this in mind in order
to fly the aircraft safely.
General precautions for use
1. Turn the transmitter ON first and then the receiver to fly the aircraft. When finished flying, turn the receiver
OFF first and then the transmitter. It is very dangerous to activate the components in reverse order as the
servo may start up inadvertently.
2. Before flying the aircraft, check that the batteries to the transmitter and receiver are sufficiently charged.
Precautions for use: Transmitter
1. Never touch the transmitter antenna while flying the aircraft. Doing so may cause loss of transmitter output,
making it impossible to operate the aircraft.
Keep the antenna of the transmitter perpendicular to the ground as best possible.
Screw Locations
There are four locations for the stick tension adjustment screws installed because the stick controlling the
throttle is ratcheted and has no tension adjustment. The #1 and #3 screws adjust the tension for the vertical
motion of each stick. The #2 and #4 screws adjust the tension for the horizontal motion of each stick. To make
the tension adjustment use a small phillips type screwdriver to turn the adjustment screws. Turning the screw
clockwise will increase the stick tension, turning it counterclockwise will decrease the tension. Once you have
completed your stick adjustments, replace the case back and install the NiCd battery pack and antenna. Be
careful to line the battery charging port pins when replacing the back cover.
WARNING:
Any other modifications made to the transmitter other than adjusting stick tension will void any and all
warranties covered by Airtronics Inc.
Keep perpendicular to
ground.
2. The transmitter's antenna is delicate. Handle with care.
3. Do not press the BIND key while flying the aircraft. The radio signal is interrupted while the BIND and trainer
keys are pressed. It may also require time to restore the signal after releasing the keys, which can be
dangerous.
Precautions for use: Receiver handling and mounting on aircraft
1. The receiver has 2 antenna wires. The thin section at the tip is the antenna reception wire, therefore mount the
antenna to the aircraft without bending the reception wire. Reception performance decreases if the reception
wire is bent.

TRAINER SYSTEM
2. The receiver antenna wires are delicate, therefore handle with care. In particular, do not pull on them with
force or push them into the case.
3. Do not cut or extend the receiver antenna wires.
4. The thick portion of the receiver's antenna is the coaxial cable. Do not use the unit with this part of the antenna
bent acutely. In addition, do not repeatedly bend this part to an acute angle because this can cause the antenna
core to break. When mounting on the aircraft, bend it as gently as possible for usage.
5. Mount the receiver antenna wires on a wood or plastic nonconductive part of the aircraft and bend so that
the two wires are 90¡ apart.
∗This is extremely important in ensuring that the aircraft receives control signals no matter what its posture,
attitude or heading.
The Trainer system in the RDS8000 transmitter allows you to connect any two Airtronics RD series transmitters
together for the purpose of training a new pilot. You can also connect the RDS8000 to either VG 400, VG 600,
RD6000, RD8000 Radiant or Vanguard PPM unit. The Trainer cord to use is the ATX Part # 97100. The RDS8000
is NOT compatible with Stylus, Infinity 660 or Quasar units.
In actual use, one of the two transmitters will serve as the Master and the second transmitter will serve as
the Trainer. The Master transmitter is held by the instructing pilot, AND IS THE TRANSMITTER THAT MUST
MATCH THE RECEIVER FREQUENCY INSTALLED IN THE MODEL! The trainer transmitter is held by the
learning pilot, and does not need to be on the same frequency as the model. The frequency of the Trainer
transmitter is unimportant because the switch of the trainer transmitter is NOT turned on during instructional
flying. Normally during training, the instructor takes the model off and flies it to a reasonable altitude.
While the Master/Trainer switch on the Instructor's transmitter is left in its OFF position, the Master transmitter
will have full control of the model. When the instructor is ready to begin training, he presses and holds the
spring-loaded switch on his transmitter which transfers control to the student.

6. Protect the antenna reception wires with a plastic pipe
(i.e., antenna pipe for car radio controller, etc.) when
mounting the receiver on the aircraft.
As long as the instructor holds his Trainer switch in the ON position, the model will respond to the commands
of the Trainer transmitter sticks allowing the student to fly the model. It is not necessary for the student to hold
the trainer switch on the Trainer transmitter.

Anchor in place with epoxy
or tape to prevent loss.
7. Prevent the antenna reception wires from contacting conductive parts when mounting the receiver on the aircraft.
Glider bodies and helicopter frames may contain conductive parts, therefore check carefully.
8. If mounting the receiver on an aircraft made of conductive material and the antenna reception wires are
surrounded by conductive materials, mount the receiver so that the reception wires extend outside of the aircraft
body. Reception can be blocked if the reception wires are shielded.
9. Mount the receiver and antenna so that they are a safe distance from ESCs (Electronic Speed Controller),
motors and engines. All such components generate noise and may adversely affect reception.
10. Location of the receiver and antenna reception wires may alter performance. If this happens, try repositioning
the receiver and antenna reception wires, ensuring the aforementioned mounting requirements are satisfied.
Once having done so, check that the aircraft and servos operate properly before taking off.
14
When the instructor ceases training, or if he feels that the student is in a situation that endangers the model,
the instructor can release the spring-loaded switch and control of the model will immediately return to the
Master transmitter. To use the Trainer system, you must plug the appropriate Trainer cable into the back of
both the Master and the Trainer transmitters. Turn on the Master transmitter and the Model. The cable will
energize the encoder section of the Trainer transmitter. Once you have verified that both the Master and the
Trainer transmitters will control the model with the spring-loaded switch in the appropriate position you are
ready to start training.
To check this, press and release the trainer button on the master radio, while observing the control surfaces
and throttle position. Make sure nothing wiggles. Adjust servo direction and trim until nothing wiggles when the
button is pressed and released. With the sticks at full deflection (full left aileron, for instance) also press and
release the trainer button to ensure that none of the surfaces or throttle wiggles.
NOTE:
Both transmitters must be programmed identically for the trainer system to function properly. All servos must
operate in the same direction, centering, end points, and other settings such as type of Modulation must be
identical.

USING THE RDS8000 MICROPROCESSOR
Airtronics has invested a large amount of design effort to ensure that the powerful capabilities of the RDS8000
are as simple as possible to use. This manual has been written to offer the user complete instructions for
either fixed-wing aircraft or helicopter models. The manual is divided into three sections: Introduction, Aircraft
(both powered and sailplane), and Helicopters. You only need to read the introduction section and the one
that applies to your type of model. In most cases, all the setup programming is accomplished through the
use of the input keys on the RDS8000 transmitter. The function(s) of these are shown below.
2. Turn ON power to the transmitter. The BIND LED of the transmitter lights.
∗If an alarm sounds and the LED does not light, the throttle sticks and Flight Mode switches are
incorrectly positioned. Repeat the setting procedure starting from Step 1.

Pairing (Binding)
When new, it is necessary to pair the transmitter and receiver to prevent interference with radio controllers
operated by other people. This operation is referred to as "pairing" or "Binding".
Once paired, the setting is remembered even after power is shut OFF, therefore the operation usually does
not have to be redone. However, under some circumstances, the receiver may not operate after turning the
transmitter and receiver ON. In such case, perform the pairing operation again.
4. While the BIND LED on the receiver is flashing slowly, press the BIND key on the transmitter. The BIND LED
on the receiver starts flashing rapidly and soon after lights solidly. This indicates that pairing was successful.
∗Unless the BIND key on the transmitter is pressed within 10 seconds, the BIND LED on the receiver will
automatically time out and stop flashing. If this occurs, you simply need to repeat steps 3 and 4.
Pairing the transmitter and receiver
1. Drop the throttle stick of the transmitter to LOW. In HELI mode, turn the flight mode of the Flight Mode switches
to Normal (N).

Failsafe
Failsafe sets the servo to a predetermined position in the event the signal from the transmitter is interrupted for
some reason and the aircraft cannot be controlled.
Set failsafe to a position that is conceivably safe should control be lost during flight, such as to drop the throttle
to LOW.
Failsafe is not factory-set and, the servo is free (not powered) if the signal is interrupted.
To clear your programmed failsafe settings and restore the factory defaults, pair the transmitter and receiver
once more.
IMPORTANT NOTE:
Pairing the transmitter and receiver clears your failsafe settings! So, only re-pair if necessary and then remember
to re-establish your desired failsafe settings.
∗When the signal is restored, normal control returns.
∗Setting is available only for CH1 through CH4. (* CH5 through CH8 cannot be set.) Also, the failsafe setting is
applied to all settings in a given channel; channel settings cannot be individually set.
3. The transmitters BIND LED will blink steadily. Continue holding the BIND button in for approximately 5
seconds until the LED goes out and then let go of the BIND button. If the LED then resumes a steady
blinking, the transition to Range Check Mode was successful.
4. Immediately turn the receiver ON, walk about 30 paces from the aircraft (approximately 90 feet) and, with
help from another person, check to make sure the servos move without problem.
If there is a problem with servos movement, try moving while maintaining the same distance from the
aircraft, and check again to make sure the servos moves without problem.
If there is still a problem with servos movement, check to make sure there are no problems with servos
connector connections and so on. Do not fly the aircraft until you have solved the problem.
∗ Range Check Mode automatically turns off in about 3 minutes, and the system changes to Normal
Mode.
Be sure to check servos movement while checking that the transmitter's LED is blinking. If the LED has
changed to constantly lit status while checking servos movement, turn the transmitter power OFF.
Repeat the process from step 1, then go into Range Check Mode.
∗ In this case, it is not necessary to turn the receiver OFF.
∗ Caution! Do not fly the aircraft while in Range Check Mode. You will be unable to control the aircraft once it
has flown a certain distance.
Setting the failsafe
1. Drop the throttle sticks of the transmitter to LOW. When using in HELI mode, turn the flight mode of the Flight
Mode switches to Normal (N).
2. Turn the transmitter power ON. The BIND LED of the transmitter lights up.
∗If an alarm sounds and the LED does not light, the throttle sticks and Flight Mode switches are incorrectly
positioned. Repeat the setting procedure starting from Step 1.
3. Turn the receiver power ON. The LEDs of the transmitter and receiver light up. At this point, try moving the
transmitter's sticks to see if the servo is operating. If it does not appear to be operating, repeat the BIND
procedure.
4. Move the transmitter sticks to the desired failsafe position. While holding the sticks in those positions, press
and hold the BIND key of the receiver. Soon after, the BIND LEDs of the receiver start flashing slowly, then
flash rapidly and ultimately stay lit. This indicates that the failsafe was set successfully.
*Press and hold the BIND key of the receiver until the receiver's BIND LEDs stay lit.
5. Turn the transmitter power switch OFF to interrupt the transmission signal and check whether the servos have
come into the set position. This check is for safety purposes, therefore perform before takeoff.
∗To change failsafe settings, repeat steps 1-4.

BAR GRAPH VOLTAGE INDICATOR
Range Check Mode
The controller has a Range Check Mode function, which lowers the transmitter's output level to check radio
signal reception. Use this function to check radio signal reception on the ground, prior to flight. To check
reception, put the controller in Range Check Mode, walk about 30 paces away from the aircraft, and check to
make sure the servo moves without problem.
As a convenience, the RDS8000 transmitter provides a transmitter battery Bar Graph voltage indicator at the
top of the Liquid Crystal Display labeled “E” and “F”. The “F” symbol indicates FULL and the “E” indicates
EMPTY. You can consider it similar to a gas gauge. The Bar Graph indicator is in addition to the normal
battery voltage that is displayed on the main screen when you select AERO or HELI by pushing the END
key twice. When the Bar Graph reads less than half you should not fly until you recharge the transmitter.
(9.2V.)
How to transmit to Range Check Mode and check range
1. Drop the throttle sticks of the transmitter to the end of the low side. When using in HELI mode, turn the flight
mode of the Flight Mode switches to Normal (N).
2. While pressing the transmitter's BIND key, turn the transmitter power ON.
∗If you hear a warning signal, correct the positions of the throttle sticks and Flight Mode switches, and repeat
the setting procedure starting with Step 1.

SECTION II COMMON FUNCTIONS
CNT (CONTROL CENTERING)
The following functions are common and applicable to both Aircraft and Helicopter programming.
The Liquid Crystal Display shows an AERO model selected. However, a similar screen will be displayed when a
Helicopter type model is selected.
Your RDS8000 allows you to fine-tune the CENTER or neutral position of the servos. After hooking up your
controls and mechanically centering all linkages to the approximate positions, press the FUNCTION down
key to arrive at the following screen for the Elevator control.
NOTE: Switches labeled with red lettering are for aircraft and blue lettering is used for helicopter.
(Note that the Aileron, Throttle, Rudder, Flap, AUX-1 and AUX-2 centering operates in the same manner
when you select that channel on the upper part of the screen. You can move across to the CNT function of
each channel as well as some of the other functions by pressing the (CH+ ) key.
IMPLEMENTATION OF CONTROL FUNCTIONS
In this section you will learn how to implement the control functions and tailor the servo movement and
centering for each control. Pressing the END key on the front panel several times will bring you to the
following screen, i.e., the initial screen that indicates the current model type and number, and the transmitter
NiCd battery pack voltage.
Press the (CH +) key to obtain the STW screen. The Elevator channel will appear on the upper part of the
screen. The model number and AERO will be present on the left side and the stop watch will indicate zero
since no time has been programmed.
By pressing the INC+/YES or DEC-/NO keys you can vary the value from 0 to + or - 100%. Default is 0%.
IMPORTANT NOTE:
It is desirable to adjust the control linkages as close as possible to the correct center positions, then use the
CNT (CENTER) commands to “Fine-tune” the exact position of the control surface when the transmitter
control is in neutral.
REV (SERVO REVERSING)
The RDS8000 allows you to electronically REVERSE the direction of rotation for each of the servos in use.
This allows you to hook up your control linkages and pushrods in the most mechanical desirable manner
without regard to the direction of servo movement. After installing your linkages, check to see if any of the
servos move in the wrong direction when you move the controls. If so proceed as follows for reversing the
elevator channel. Reverse for all other channels is done the same way.
Using a large amount of electronic centering adjustments will decrease the total throw available for that
channel. In particular, centering adjustments greater than + or - 50% will tend to make the extreme stick
position on one end less responsive!
Press the FUNCTION down key to arrive at the following screen:
Move the control stick for the elevator function.
If the Elevator servo moves in the wrong direction, press the INC +/YES key to change the direction.
Move the cursor to the channel whose direction you wish to change (one of the following: EL, AL, TH, RU, G,
P/F, 7 or 8) and set REV function.

23
RST (DATA RESET)
HOW TO SELECT MODEL SET-UPS: M-SL (Model Select)
If you want to “UNDO” all of your programmed parameters at one time, you can use the RST function.
However, be certain that is what you want to do, since this function will reset all settings to the factory default
settings. The RST function will only affect the specific model that you have selected. All other models in
memory are unaffected by the RST function.
The RDS8000 has built in memory to store ten model setups in any combination of model types. To use or
modify one of the model setups you first must select M-SL in the "etc" menu. Assume that you want to select
a second model. To do so, press the END key to bring up the initial screen that indicates transmitter voltage
and model number.
Press the END key to select the initial AR 1 screen that indicates the Transmitter NiCd pack battery voltage.
Now, press the CH + to access the STW (Stopwatch) screen. This screen allows you to move up and down
as well as left and right on the screen in the RDS8000 program.
Press the (CH +) key to scroll to “etc”. Use the FUNCTION down key to select MSL. Next press the INC +/
YES key and the screen will flash MSL to indicate you can select a second model. Press the INC +/YES key
again to select the next or following model such as AR2.
Press the END key three times to return to the initial screen which will show the model number and the
transmitter battery voltage reading.
Press the CH + key several times to move across the CH indicator portion of the screen until it reads “etc”.
Now, press the FUNCTION down key three times to move down in the menu until you reach the RST
(Data Reset) screen.
NOTE: if the model type is incorrect, i.e., HELI rather than AERO, continue with the model selection
procedure. The model type can then be selected on the TYP screen.
TYP (MODEL TYPE)
First, press the INC+/YES or DEC-/NO key to select the model you would like to reset. To reset all data for
this model to default settings press the (CH +) key and the screen will flash YES. Now, press the INC +/YES
key and the screen will indicate OK! All paramameters on this specific model number have now been reset to
default values. Press the END key twice to return to the STW screen.
To select the type of model you wish to program, press the (CH+) key to scroll to “etc”. Next press the
FUNCTION key to select TYP. Now press the (CH+) key to select the next model type, either HELI or AERO.
The screen will flash YES with the type of model indicated on the LCD display. To confirm your selection,
press the INC+/YES key and the screen will indicate OK!
Press the END key three times to return to the inital screen that will then show your model number/type and
transmitter battery voltage.
24
25
STW (STOPWATCH)
INT (INTEGRAL TIMER)
The RDS8000 offers a built-in timer and allows the pilot to use the stopwatch function in either elapsed time
or countdown mode.
The Integral Timer function of the RDS8000 is activated each time the transmitter power switch is turned on,
and counts up to 99 hours and 59 seconds at all times when the transmitter is turned on. This indicates how
many hours of actual use you RDS8000 transmitter has operated. You may reset the timer to zero at certain
intervals, for instance, each time you charge the transmitter NiCd battery pack.
The INT (Integral Timer) function is located in the “etc” column of the menu, directly below STW (set). Use
the FUNCTION down key to access the INT screen. Note that it will have some indication of how long the
transmitter has been operating. It may look like the following screen, but with a different time shown. The
time will show a change for each elapsed second and minute. If you want to reset the Integral Timer to Zero,
press the INC +/YES and the DEC -/NO keys simultaneously.
NOTE: To program a time, you must be in the BASIC OFF mode of operation.
To use the stopwatch, press either the (CH -) or the (CH +) key to select “etc” on the Channel indicator display.
Now press the FUNCTION down key to scroll through the screens until you find the STW screen with the
flashing indicator. This is where you set your stopwatch countdown time. The STW (set) screen is just above
the INT screen as shown on the Menu Structure, page 38.
You can display the Integral Timer function instead of the STW (stop watch) function on all Channel screens.
While you are in the INT screen, press the (CH +) key to obtain the following screen.
Use the INC +/YES key to set a value for the start of your count down. As an example set it at 10.00 minutes.
The screen will look like the following illustration. If you want to decrease the time, use the DEC - /NO key.
If you want to clear the time, press the INC +/YES and the DEC - /NO keys simultaneously.
You can now start the stopwatch from any channel-indicator screen that displays the STW screen and the
programmed time. Press the INC+/YES key to start or stop the countdown.
When the time reaches 10 seconds, a tone will be heard every second as it counts down to zero. When the
timer reaches zero, a steady tone will be heard and it will start counting up. Press the INC+/YES key and
DEC-/NO key simultaneously to reset the timer to your previously-programmed time.
26
Press the INC +/YES key and the bottom line of the screen will change from INH (inhibit) to read ACT (active).
You can press either the DEC -/NO key or the INC +/YES key to change it back to INH. Most pilots prefer to
have the Stopwatch function displayed on all Channel screens, rather than the Integral Timer, therefore, they
leave the Integral Timer DSP at INH (inhibit). Press the END key twice to get back to the top of the “etc”
menu column.
27
NAM (NAMING YOUR MODEL)
EXP (EXPONENTIAL)
The RDS8000 provides the capability to designate each of the 10 models you have programmed by use of a
3 digit name. Use the (CH +) key to select the “etc” screen. Press the FUNCTION down key twice to select
the NAM screen.
The RDS8000 allows the pilot to choose two settings for Exponential throw for each of Elevator, Aileron
(and Rudder in helicopter mode).
Exponential throw is primarily used to “soften” or decrease the sensitivity of a control stick around the neutral
point. With Exponential disabled, a servo will move in proportion to the amount of control stick deflection, i.e.,
50% stick deflection will result in 50% servo travel; 75% stick deflection will result in 75% servo travel.
Exponential settings DO NOT change the amount of travel available at 100% stick deflection, but rather it
changes the amount of the servo travel at stick deflections less than 100%. The first 25% of stick deflection
may be set to result in only 10% of total servo, throw making the control less sensitive around neutral. See the
following illustrations.
Now press the (CH +) key to select the screen for model number one. The first character will flash to indicate
you can change that letter.

Press the INC +/YES key to scroll through the letters of the alphabet and make a change in the first letter.
You many use any combination of LETTERS (upper and lower case), NUMBERS, Colon (:), Dash (-),
Character, or blank space to designate a model. When you have finished the first letter or number, press the
(CH +) key to move to the next letter and set it in a similar manner. The DEC -/NO key can also be used to
change a letter or number in the opposite direction. Press both the INC + /YES and DEC -/NO keys
simultaneously to return to the default setting of AR 1. Once you have named the model, press the END key
twice to return to the “etc” column heading.

If you have not used Exponential functions before, you will want to start with a small amount of Exponential
(10 to 20%) to determine whether you like this sort of control response. Exponential is most useful where
strong control response is desired at extreme stick positions but softer response to small stick movement is
desired in order to make very accurate small corrections to the flight path.
The switch positions for Exponential #1 and Exponential #2 correspond to the Dual Rate switch positions of
Elevator and Aileron. Exponential #1 is with the Dual Rate switch in the down i., (Off) position. Exponential
#2 is with the Dual Rate switch UP (ON) position. (Note however that you can leave the Dual Rate
adjustments for Elevator and Aileron set at 100% which is no rate, so that switching a Dual Rate switch ON
will activate Exponential only.
NOTE: Setting the Exponential with a positive number will make servo movement soft in the neutral area of
the stick movement. Setting the Exponential with a negative number will make servo movement faster in the
neutral area and softer at the end of the stick travel.
28
29
As an example, to set Exponential for elevator, access “EL” in the Channel area by using the (CH+) key.
Now press the FUNCTION down key to select the EXP display for the Elevator Channel as shown below.
In the above example, we set Exponential #2 to be 20% of the maximum for the Elevator channel. This is a
good starting point for determining the suitability of Exponential throw for your aircraft and flying style.
You can actually have two different Exponential settings if you desire. One for switch position #1 and another
for switch position #2. However, when you first start using Exponential throw, it is usually best to leave the
switch #1 position at 0% which is linear throw.
In general, large amounts of Exponential are useful only where very large control-surface deflection is
required at extreme throw, while very small amounts of control response are necessary for smaller control
stick inputs. One example where large Exponential settings may be useful is the highly maneuverable
“Competition FUN FLY” style model. For most sport and aerobatic models, an Exponential setting from
+10% to +25% will give the desired “softness” around neutral.
This screen shows you the present Exponential status of the elevator channel and when a Dual Rate
Exponential switch is set to ON position, the Exponential setting for that control function. The possible range
for Exponential settings is from -100% to +100%. Note that 0% is linear. A negative value will speed up the
response and it will make the stick movement more sensitive around the neutral position.
To set an Exponential rate in this example, turn the Dual Rate switch for Elevator to the ON upward position.
Note that the display changes to Exponential #2. You can set the value for the Elevator channel Exponential.
Press the INC+/Yes key to set a positive value of Exponential function as indicated below.
30
CAUTION: Proceed with care when setting Exponential functions to ensure that you will have adequate
control deflection available in any possible switch position. Setting Exponential to a very high or 100%
setting will require very large stick movements to achieve small control responses. Always make sure that
you are aware of the present status of any rate assignments that you have selected! For the most flexibility
in setting up an aircraft model to your liking , study the available options for Dual Rates, End Point
Adjustments, and Exponential. The combinations of these options allows several possible set-ups.
The Exponential for the Aileron Channel is set in the same manner as for the Elevator.
The AI D/R switch located above the right stick assembly is used when setting the Exponential Throw.
31
CPY (DATA COPY)
A valuable feature of the RDS8000 is the Data Copy Function. With this function, the entire set of control
parameters for one aircraft can be ‘copied’ from one model set-up into another. For instance, if you have
your aircraft program in Model #1 and nothing in Model #3, you can copy the Model #1 program into Model
#3 with the copy function.
On the previous screen, the destination has been set to Model #3. MAKE CERTAIN that the current model
setup is not one you wish to save, because when you copy the Model #1 set-up into Model #3, all data that
was in Model #3 is replaced with the Model #1 data! At this point Model #3 data is still intact, so if you wish
to change the destination for the copied data, do so before proceeding.
Having copied your control set-up, you can now use MSL (Model Select) to access the Model #3 program
and then make control changes to that set-up. This allows you to experiment with different control options
without changing your original parameters (in this example Model #1).
Having selected both the data source (Model #1) and the desired destination (in this example Model #3), you
can now proceed to confirm the copy function.
Press the CH + > key to access the next screen as shown below. The “YES” will be blinking.
To use the CPY (copy) function, select “etc” on the Channel indicator using either the (CH –) or (CH +) key.
Note that you must be on the STW screen to move horizontally across the screen to “etc”.
Press the INC +/YES key to confirm your data copy function. The screen will change to the following screen to
inform you that the process has been completed, and that Model #1 and Model #3 now have the same data.
Press the FUNCTION down key to select the CPY (copy) Function.
Press the END key to return to the CPY select screen.
For this example, assume you want to copy the set-up of Model #1 (which you selected), to Model #3. The
first number on the screen indicates the model number you are copying. The second number indicates the
destination model. Press the INC +/YES key to change the destination to indicate Model #3. Note that one
of the small triangles is blinking which indicates there is another screen associated with this function.
32
33
SW-R (SWITCH REVERSE)
CLK (CLICK)
The SW-R Function allows you to reverse the action of the six toggle switches located on your RDS8000
transmitter. The default of the SW-R Function is the NOR (normal) position. CAUTION! The switch reversal
function is not individually selective. If you change it from NOR (normal) to REV (reverse), all switches will be
reversed in their action!
The RDS8000 transmitter is factory-set to emit an audio tone ("Click") whenever the programming keys are
pressed, when values are changed, and when the stop watch function is started, stopped or reaches the final
ten seconds of countdown.
To access the SW-R Function, select “etc” on the Channel indicator using either the (CH -) or the (CH +) key.
Note that you must be on the STW screen to move horizontally across the screen to “etc”.
It is possible to disable the “Click” or audio tone, using software settings. When disabled, ONLY the stopwatch
count-down emit cause an audio tone.
To set or disable the “Click” function, select “etc” on the Channel indicator using either the (CH –) or the
(CH +) key.
Press the FUNCTION down key to scroll down to the SW-R (switch reverse) screen.
Press the FUNCTION down key to access the CLK (CLICK) screen.
Now, press the INC +/YES or the DEC -/NO key to change the indication from NOR to REV. All switches on
the transmitter are now reversed in their function. Press END to return to the STW screen.
Press the INC +/YES key to change the indication from ACT to INH, to disable the Click function. (pressing
either the INC +/YES or the DEC -/NO key will toggle the function between “INH and “ACT” settings
NOTE: NOR (normal) default (switch off) position: For top toggle switches is the up position and all four slide
switches on the front of the transmitter are down or pulled towards you. Using the SW-R feature will change
the default off position: To toggle switches down and all four slide switches pushed forward or up position as
default off.
Press the END key to return to the STW screen.

T-CUT (THROTTLE-CUT)
Another useful function provided by the RDS8000 for engine-powered models is T-CUT, (Throttle Cut).
Normally you set your throttle stick in the extreme low position and use EPA and the digital trim to obtain a
steady engine idle speed. However, to stop the engine at the end of the flight you would have to use the
throttle digital trim and later re-trim for proper idle. The T-CUT function eliminates that by providing a button
that overrides the throttle stick low position and drives the throttle servo to a lower position, stopping the
engine. The throttle stick must be in the low position for the throttle cut to function.

Turn the transmitter power ON and press the END key until you come to the default main screen. This screen
will show AR1 as the aircraft type, and the NiCd battery voltage.
Press the (CH+) key to scroll across the CH (channel) indicator on the screen to “etc”.
Press the FUNCTION down Key once to access the MSL (model select) screen.
Use the four center buttons in the function panel to navigate
through the menu’s. (UP / DOWN / LEFT / RIGHT)

Press the INC+YES key until the screen reads HL2 (HELI model 2). Now press the END key. The screen will
show model number two, which is a helicopter setup. However, since you are a fixed wing aircraft pilot, you
want all of the transmitter setups to be fixed wing aircraft, the TYP (type) of aircraft must be changed from
HELI to AERO.
D/R (DUAL RATE)
Dual Rate adjustments, when operating your RDS8000 transmitter in the AERO mode, permits you to switch
from your "standard" control deflection to a reduced amount of throw by simply flipping a switch. The actual
speed of the signal processing and servo movement are not affected by the Dual Rate settings, only the
amount of total throw available. Note when operating the Helicopter mode, Dual Rates for Elevator, Aileron
and Rudder are set for each Flight Mode.
The RDS8000 allows Dual Rate settings for Aileron and Elevator. To access the Dual Rate setting for Elevator
when you are on the STW or REV screen, press the FUNCTION down key to reach this screen.
TYP (Type of Model)
To change the type of model, press the FUNCTION down key to select the TYP (model type) screen.
The screen tells you the present rate status, and when a Dual Rate is set to the ON position, the alternate
rate for that control function that is presently set in the program. We are showing an example for the
Elevator channel, however, all of the other channels are set in the same way.
Note that one of the small triangular indicators will be blinking to show that you should press the (CH+) key.
Therefore, press the (CH+) key and the screen will change to AERO with a flashing YES.
To confirm the change of aircraft type, press the INC+/YES key. The screen will then change to read OK! As
shown on screen below to indicate the model type has been changed to AERO for model #2. Press the END
key twice to return to the STW screen. The same procedure as above can be used to change model #4, 6, 8
and 10 from HELI to AERO.
The Dual Rate setting can be varied from 0 to 150%. Default for Dual Rate 1 is 100%. We recommend you
leave it a that setting and only change the setting for Dual Rate 2. i.e., The convention for Dual Rate reducedthrow is the switch in the UP position to Turn ON Dual Rate. When you do so, note that the Screen will
appear as follows. Press the INC +/YES or DEC -/NO key to increase or decrease the value. An initial setting
of 50% is a good starting point and you can tailor it later following a test flight.
The Dual Rate switch for Aileron is located above the right stick assembly and is labeled AI D/R. Aileron
Dual Rates are programmed in the same manner as the Elevator Dual Rates. To set it for Aileron, place the
AI D/R switch in the upper position and use the DEC -/NO key to reduce the value shown on the screen to
something less than 100%.
The RDS8000 permits you to set Dual Rate for the four distinct Flight Modes, e.g., Normal, 1, 2 and 3 for each
helicopter. See page 67, PITCH Curves (FLIGHT MODES), for the description of the available Flight Modes.
Dual Rate in a specific Flight Mode is set by first selecting D/R for Elevator, Aileron or Rudder. Press the FMODE key to scroll through Flight Mode N, 1, 2 or 3 and set the value for Dual Rate. The Dual Rate can be
varied from 0 to 150% The default value is 100% for all Dual Rates.
CAUTION: Prior to take off, check the position of both Dual Rate switches to make sure they are in the
position you want!
