CONNECTORS

Your RD8000 unit is equipped the new 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!

AUDIO LOW VOLTAGE ALARM

Your RD8000 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 dont 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.
TRANSMITTER BATTERY REMOVAL
The NiCd battery in your RD8000 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) 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.

Negative 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 RD8000 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.

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. 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!

RST (DATA RESET)

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. 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 RD8000 program.
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.
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.
HOW TO SELECT MODEL SET-UPS: M-SL (Model Select)
The RD8000 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 (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. 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.

If you desire, you can display the Integral Timer function instead of the STW (stop watch) function on all of the Channel screens. To do so while you are in the INT screen, press the (CH +) key to obtain the following screen.
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 Stop watch function displayed on all of their 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.

NAM (NAMING YOUR MODEL)

The RD8000 provides the capability for you 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.
Now press the (CH +) key to select the screen for model number one. The first charater will be flashing 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 completed designating your present model, press the END key twice to return to the etc column heading.

EXP (EXPONENTIAL)

The RD8000 allows the pilot to choose two settings for Exponential throw for each of the primary flight channels, Elevator, Aileron (and Rudder in helicopter mode). Exponential throw is primarily used to soften or decrease the control stick sensitivity of a control around the neutral point. With Exponential disabled, a control funtion servo will move in an amount proportional 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 that will occur with 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.

On the previous screen, the destination has been set to Model #3. MAKE CERTAIN that this 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 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.
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 END key to return to the CPY select screen.

SW-R (SWITCH REVERSE)

The SW-R Function allows you to reverse the action of the six toggle switches located on your RD8000 transmitter. The default of the SW-R Function is in the NOR (normal) position. CAUTION! The switch reversal function is not selective. If you change it from NOR (normal) to REV (reverse), all switches will be reversed in their action! 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 toetc)
Press the FUNCTION down key to scroll down to the SW-R (switch reverse) screen.
Now, press either 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.
NOTE: All switches as a NOR normal default (switch off position): Both top toggle switches in the up position and all four slide switches on the front of the transmitter are down or pulled towards you. Using the SW-R feathure will make the default off position: Both toggle switchs down and all four slide switches pushed forward or up position as default off.

CLK (CLICK)

The RD8000 transmitter normally is set to emit an audio tone when ever 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. It is possible to disable the Click or audio tone, using software settings. When the Click tone is disabled, ONLY the stop watch count-down will still cause an audio tone to be emitted. 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 access the CLK (CLICK) 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
Press the END key to return to the STW screen.

T-CUT (THROTTLE-CUT)

Another useful function provided by the RD8000 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 low engine idle speed. However, if you want 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 solves this problem by providing a push button that, when pushed, overrides the throttle sticks low throttle position and drives your throttle servo to a lower position, stopping the engine. The throttle stick must be in the low position for the throttle cut to function.
In order to use T-CUT, press either the (CH -) or the (CH +) key to select TH on the Channel indicator.
Next, press the FUNCTION down key several times to obtain the following screen.
Press the DEC -/NO key to set a value of 100%. Place the throttle stick in the extreme low position. Press and hold down the Throttle Cut push button located above the elevator/aileron stick assembly. The throttle servo will then rotate further to close the engines carburetor and stop the engine.

PROGRAMMING FOR AIRCRAFT

INITIAL SET-UP OF TYP (MODEL TYPE) When you receive your RD8000 unit the transmitter is preprogrammed for both fixed wing aircraft models as well as for helicopter models as follows:
Model #1 Model #2 Model #3 Model #4 is setup AERO is setup HELI is setup AERO is setup HELI Model #5 Model #6 Model #7 Model #8 is setup AERO is setup HELI is setup AERO is setup HELI Model #9 is setup AERO Model #10 is setup HELI
If you fly only fixed wing model aircraft, you can change models 2, 4, 6, 8 and 10 to aircraft. Turn the transmitter power ON and press the END key untill you come to the default main screen. The inital screen will show AR1 which indicates the aircraft type as well as showing 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.
Next, press the INC+YES key until the screen reads HL2 (heli model 2). Now press the END key and the screen will show that you have selected 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.

TYP (Type of Model)

To change the type of model, press the FUNCTION down key to select the TYP (model type) screen.
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 noted above can be used to change model #4, 6, 8 and 10 from HELI to AERO.

D/R (DUAL RATE)

Dual Rate adjustments allow you to switch from your standard control deflection to a reduced amount of throw by simply flipping a switch. The Actual speed of signal processing and servo movement are not affected by the Dual Rate settings, only the amount of total throw available. The RD8000 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.

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. It is important to understand that the term Dual Rate is used because it is an old and familiar description. We are showing an example for the Elevator channel, however, all of the other channels are set in the same way. The Dual Rate setting can be varied from 0 to 150%. Default for Dual Rate 1 is 100%. We recommend you leave it at that setting and only change the setting for Dual Rate 2, i.e., when the Dual Rate Switch on the upper left side of the transmitter panel is turned ON. The normal convention for Dual Rate reduced throw 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 Rate is programmed similar to that as done for Elevator. To set it for Aileron, place the AI DR switch in the upper position and use the DEC -/NO key to reduce the value shown on the screen to something less than 100%. CAUTION: Prior to taking off your model, check the position of both of your Dual Rate switches to make sure they are in the position you want!
EPA (END POINT ADJUSTMENT)
The RD8000 allows you to adjust the End Points, or travel limits, for all flight channels. In general, it is best to use as close to 100% servo throw as possible. This allows for the best possible resolution and centering of all control surfaces. However in some cases it is not possible to use full servo movement such as those instances where short control horns must be used because of aircraft design considerations, or with fixed length control horns such as a throttle arm. Assume we want to adjust the EPA of the Elevator channel servo. To electronically do so, we first bring up the STW (stopwatch) screen as previously instructed in INITIAL SETUP. Next press the FUNCTION down key until the EPA screen appears for the Elevator channel.
The EPA of the Elevator channel can be adjusted from 0% to 150%. By moving the elevator stick up and down, you will see the LCD arrow change according to the direction you are moving the stick. To set the UP EPA, move the stick back past the neutral position and release the stick. You can increase or decrease the amount by using the (INC+) or (DEC-) function keys.
Note that you can move across the menu using the (CH+) or (CH-) keys to adjust EPA for all other channels. To adjust the EPA on Gear and Flap channels simply move the toggle switch up or down and adjust the EPA accordingly.
G (Landing Gear End Points)

In most cases, (almost all cases in the past) the total servo throw for the landing gear function could not be set by the transmitter, because most retract servos are SWITCHED (non-proportional) servos. With these servos, mechanical adjustment was the only method available to ensure proper operation of the retracts. Airtronics now offers a high Torque PROPORTIONAL retract servo, p/n 94739. With this servo and the RD8000 transmitters, End Point Adjustments for the retract servo are possible, independently setting the Down and UP lock positions in mechanical retracts, and precise adjustment of the air valve in pneumatic retracts. To use this function, select the EPA function as shown on the previous screen. Press the (CH +) key to scroll across the Channel indicator on the screen until you reach G (Landing Gear).
Note that you must set the value for UP and Down landing gear by use of the INC +/YES and DEC -/NO keys. Activate the Landing Gear toggle switch located on the upper left top of the transmitter when setting the values for the Landing Gear. You can vary each one from 0% to 150%. The default values for Landing Gear are 125% and +125%. To restore the landing gear channel to the default values, press the INC and DEC keys simultaneously.
TRM (TRIM MEMORY) The RD8000 offers the Trim Memory Function on all four of the flight control channels and the Flap Channel. Trim Memory for Elevator, Aileron, Throttle, and Rudder is input by the Digital Trim keys. It can also be set when you use the INC +/YES or DEC -/NO keys to input trim. Any trim that you set while your model is in flight by use of the Digital Trim keys will automatically be stored in memory for that specific channel and model. The Trim value in % that you set during flight is shown on the TRM screen for each Channel. In addition, there are bar graph indicators on the screen at all times that visually show how much trim has been set for Elevator, Aileron, Throttle and Rudder channels.
3 POSITION FLAPS (FLAP SWITCH) Using channel 6 as a flaps only channel, you are able to adjust the 3 flap positions. Up 0% flaps, 50% flaps and 100% full flaps down. By starting in the default screen, push the function CH+ key to move the curser to the right untill you reach the P-F. All of your flap adjustment is done with the CNT and EPA. You will be using your EPA and servo centering to change the persentages of how much flap you would like. First move the 3 position switch to the middle postion. This will position the servo to its center position. With out using the servo centering feature, install the servo arm so the arm is as close to 90 deg as posible. Now move the 3 poistion flap switch to the up postion and setup your linkage so your flaps will be at 0%. After your linkage is set you can now move the 3 position switch to the middle. This will move your flaps down to the 50% position. Moving the 3 position switch to the last or full down position will give you full 100% flaps down. With the 3 position swtch in the mid position, you can adjust the amount of flaps down in this position with the servo centering feature. REMEMBER! changing the servo centering will change both up and down end points. Besure to readjust both end points after you change the servo centering. After adjusting the mid flap position, you can now adjust both the up and full down positions with the EPA feature.

Press the FUNCTION down key to select the CR:LA (Crow left aileron) screen.
Next, press the INC +/YES key to program a value of 25%. Here we have set CROW for the Left Aileron at 25%. The Left Aileron now will raise 25% of its travel upwards while the flaps deploy downwards while in the Landing Mode. The Landing Mode, Flap deployment and CROW are all controlled by the position of the FLAP (throttle) stick. The range of adjustment for CROW is from +100% to 100%. The default value is 0%.
Now, press the FUNCTION down key to move down to the CR:RA (CROW right aileron) screen. Press the INC +/YES key to set it at 25%. Now both ailerons respond identically to the CROW command.

OPTION MENU SCREEN

In the advanced programming you have the ability to turn off unused programming screens with the OPTION MENU SCREEN. This is vary useful and vary convenient when one of your models only requires some features. For example one aircraft is used as a triainer and you do not need to use any C-MIX, CROW, AI-DIF, DELTA, V-TAIL, you can go to the OPT screen and turn them off so they will not display in the normal programming screens. If you decide later that you want to use a feature you have turned off, you can at anytime use the OPT to turn the feature back on. NOTE 1: Turning off the feature only removes it from the programming screen. It will not however turn off the feature. Example, you had activated your FLAPE for Flaperons and then in the OPT screen you turned FLAPE off. Your Flaperons will still be active but you will not see the FLAPE screen in the programming menu. NOTE 2: This feature is best used on an aircraft or helicopter after you have setup your need on all the time features. For example the swash plate type for a helicopter, once you select the swash plate type you can then turn the swash plate type screen off because you have no adjustments in that screen and by turning the screen off you will not mistakenly change the swash plate type.
Before turning off any unused feature screens, make sure they are at there default setting or do not have any affect on any control surface. Use the CH+ key to move to the etc in the CH area of the main screen. Next use the FUNCTION down key until you reach the OPT screen. Now press the YES key, the OPT will now flash 3 times. Now you can use the FUNCTION down key to view all the feature screens that can be turned off. Turning the feature on or off is done by using the YES or NO keys. After selecting YES or NO, you can now press the END key to exit out of the OPT screen. Pressing END 3 times will bring you to the main screen.

F. Mode 1 and 2

F. Mode 3 or Hold
To program your pitch curves, press the (CH ) or (CH +) key to select P-F on the Channel indicator.
Next, press the FUNCTION down key and scroll down to the CV-PH screen.
Press the F-MODE (flight mode) switch to toggle through modes 1, 2, 3 and Normal.
Now use the F-MODE switch to select the specific flight mode that you want to adjust. As an example, if you wanted to adjust CV-P2 in Normal flight mode, press the FUNCTION down key to select CV-P2. The default value for the Normal flight mode of 55% will be shown.
Press the INC+/YES key to set an increase in value or press the DEC-/NO key to set a lesser value. Press both INC+/ YES and DEC-/NO keys simultaneously to return to the default value.
Fine tuning of the Hover Pitch is also available by use of the HOV-PT digital trim switch located above the throttle stick. NOTE: HOV-PI and HOV-TH trims are used only for adjustment in flight mode N (normal). They have no affect on Flight Mode 1 or 2.

HOV-PI + Digital Trim

HOV-TH + Digital Trim
In normal operation you will usually set the approximate Hovering Pitch with the software in the Pitch screens then adjust as needed for various weather and flying conditions with the HOV-PI (hover pitch) digital trim switch.
THROTTLE CURVES (FLIGHT MODES)
The throttle curve for each flight mode has five points that can be adjusted to suit your specific needs. Within each throttle curve these points are referred to as PH (high pitch) P3, P2, P1 and PL (low pitch). The range of values and default settings for each is shown below. To activate P3 and P1, press the YES key when in P3 or P1 screens. To set back to default, press both the YES and NO keys at the same time.

FLIGHT MODE Normal

Curve Point PH P3 P2 P1 PL PH P3 P2 P1 PL PH P3 P2 P1 PL
Minimum -25% -25% -25% -25% -25% -25% -25% -25% -25% -25% -25% -25% -25% -25% -25%

F. Mode 1and 2

To program your throttle curves, press the (CH ) or (CH +) key to select P-F on the Channel indicator.
Now use the F-MODE switch to select the specific flight mode that you want to adjust. As an example, if you wanted to adjust CV-P2 in Normal flight mode, press the FUNCTION down key to select CV-P2. The default value for the Normal flight mode of 50% will be shown.
Fine tuning of the Hover Throttle is also available by use of the HOV-TH digital trim switch located above the elevator stick.

REVOLUTION MIXING

The RD8000 provides for setting Revolution Mixing for each of the four Flight Modes. Each Flight Mode has its own curve for adjusting tail rotor position in response to the throttle/collective stick movements. The default settings for RV.H (Revolution Mixing High Point), RV.M (Revolution Mixing Mid Point), and RV.L (Revolution Mixing Low Point) are as follows: FLIGHT MODE Normal F. Mode #1 F.Mode #2 F.Mode #3 RV.H 20% 0% 0% 0% RV.M 0% -2% -5% 0% RV.L -20% -5% -10% 0%
To program Revolution Mixing, press either the (CH ) or (CH +) key to select RU ( rudder) on the Channel indicator.
Next, press the FUNCTION down key to select RV.H which is the revolution mixing high point.
Use the INC +/YES or DEC -/NO key to change the default value if you desire to do so for any of the three flight modes. In this example we have set RV.H for the Normal flight mode to + 25%.
The same procedure can be used to input values for RV.M and RV.L. Press the Flight Mode switch to select the different Flight Modes.

GYRO ADJUSTMENT

The RD8000 allows you to set the Gyro sensitivity of your helicopters gyro if it has that capability. The gain of the gyro can be adjusted for all of the four Flight Modes and have 2 settings for each. In this manner the pilot can adjust the gyro for a suitable level of sensitivity (gain) for one flight mode (for instance hover), and by changing to a different flight mode alter the sensitivity for either more or less stabilization. Note that you must be using a gyro that offers remote sensitivity adjustment.
Press either the (CH ) or the (CH +) key to select G (Gyro) on the Channel indicator.
Now, press the FUNCTION down key several times to access the GYR (gyro) screen. The display will look like the following screen when the Normal flight mode is selected.
To adjust the gyro sensitivity for a specific flight mode, press either the INC +/YES or DEC- /NO key. Default values are : Normal 100%, F.Mode #1 50%, F.Mode #2 60% and F.Mode #3 100%. The range of adjustment is from 150% to + 150%. Press the Flight Mode switch to change from one flight mode to another.
Fine tuning of your gyro sensitivity for the various flight modes can be accomplished by flight tests.

TRM (TRIM MEMORY)

The RD8000 offers the Trim Memory Function on all four of the flight control channels. Trim Memory for Elevator, Aileron, Throttle, and Rudder is input by the Digital Trim keys. It can also be set when you use the INC +/YES or DEC -/ NO keys to input trim. Any trim that you set while your model is in flight by use of the Digital Trim keys will automatically be stored in memory for that specific channel and model. The Trim value in % that you set during flight is shown on the TRM screen for each Channel. In addition, there are bar graph indicators on the screen at all times that visually show how much trim has been set for Elevator, Aileron, Throttle and Rudder channels.

Dual Rate adjustments allow you to switch from your standard control deflection to a reduced amount of throw by using your flight mode switches. The actual speed of signal processing and servo movement are not affected by the Dual Rate settings, only the amount of total throw available. The RD8000 allows Dual Rate settings for Aileron, Elevator and Rudder. 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.
The screen tells you the present rate status and the flight mode that you have selected. It is important to understand that the term Dual Rate is used because it is an old familiar description. We are showing an example for the Elevator channel. However, all of the other channels are set in the same way. Dual Rate settings can be varied from 0 to 150% for each flight mode, N, 1, 2 and 3. Default for all flight modes are at 100%. Select each flight mode using the F-MODE key and set the value for dual rate. An initial setting of 50% is a good starting point and you can taylor it later following a test flight.
CAUTION: Prior to taking off your model, check the positions of your flight mode switches and make sure they are in the position you want.
DTM (DYNAMIC TRIM MEMORY)
Dynamic Trim Memory (DTM) is an advanced function that can be used in conjunction with the Flight Mode OPTIONS. When activated Dynamic Trim Memory allows you to make trim changes while in any flight mode WITHOUT affecting any other flight mode or model. Flight Modes are used to allow activation of the DTM function. The four flight modes are: NORMAL F.M. #1.IDLE-UP 1 F.M. #2.IDLE-UP 2 F.M. #3..THOTTLE HOLD Activating DTM will allow trim changes made in one flight mode to affect ONLY that specific mode. To activate Dynamic Trim Memory, press the (CH +) or the (CH ) key to select etc on the Channel indicator.
Now, press the FUNCTION down key to scroll down the menu to the DTM screen.
Press the INC +/YES or the DEC -/NO key to change DTM to ACT (active). Pressing either key will toggle the indication from ACT to INH. Press the END key to return to the STW screen.
Once activated, the Dynamic Trim Memory function is transparent to the pilot. Simply activate a Flight Mode, (for instance Normal) and trim the aircraft for stable hover using the digital trim keys. Then, switch to another flight mode, and do the same as desired. Note that when you change flight modes, the servos affected by the DTM function will return to the original neutral position regardless of the value of trim set-in for the previous flight mode. However, the throttle channel is an exception to the rule. The trim that is set for one flight mode will affect all other flight modes. Also be aware that the throttle trim key only affects the low throttle position of the throttle servo. Throttle trim DOES NOT affect the collective pitch servo.
