HELICOPTER SETUP INSTRUCTIONS
The following example shows how the T8U may be programmed for a contest helicopter model. The settings presented here are for a typical model. Your models settings are likely to vary from these, but the procedures given will still be applicable. 1. Memory Selection 7. Throttle Cut Setting Use the Model menu Select function [MSL] After a flight, use the Throttle Cut function to to select a model memory. Choose the kill your engine with the trainer switch. There is Helicopter Setup using the SEL function from no need to fumble with trim, and the idle trim Model menu.

This example assumes and set the desired switch (we recommend using youre using model memory 2. the trainer switch F, in the down or momentary position). Move the throttle stick a few clicks above idle, then press the (+)/() keys simultaneously to memorize the position. This 2. Name your model using the Model Name makes it so the engine cut function will only [MNA] function in the model menu. operate when the throttle is below the set point, so the engine cant inadvertently be shut off in flight.

Another use for a programmable mixer The main rotors RPM can decrease due to increased loads whenever full cyclic control is used, like when doing a roll. To help keep the RPM up, you can use a mixer with Master = AIL, Slave = THR. About 10% mixing is a good starting point for both directions.
Next, move to the rudder offset setting and set OFST to keep the tail rotor pitch angle to nearly 0, since there is no torque. Your numerical value may vary from those shown.
20. Trim Offset Setting The Trim Offset menus may be adjusted for Idle-up 1 and Idle-up 2. Aileron, elevator, and rudder trims may be offset to different positions so that the model flies straight ahead during normal flight. If you find you need some trim offsets in IDL1 or IDL2, call up whichever of the OFST-1 or OFST-2 menus you need. Recommended settings for aileron and elevator offsets are small, from 6% to 10% or as needed.
18. Pitch Curve Setting. Move to the PI-CRV HOLD menu and activate. During autorotation, high pitch is used at both the HIGH and LOW sides, so set the HIGH and LOW rates to their maximum values: 0 and 100% respectively.
Rudder offset is set by the Revolution Throttle Hold function set previously, so is not included in this menu. 21. Delay Settings Delay settings are used to prevent sudden trim changes due to different settings in different
flight conditions. You can set different delays for aileron, elevator, and rudder. The delays you set apply to all flight conditions. We recommend trying very small values for the initial settings, say 5 - 10%. A 25% delay is about a half-second transit time between neutral settings.
22. Gyro sensitivity should be controlled with the CH5 switch. High is normally used for hovering, and low in other flight conditions.
You may use the Hovering Pitch and Hovering Throttle functions for fine trimming changes due to humidity, etc. This concludes the example setup procedure for helicopters. Be sure to browse through the pages following this example to see what other menus are available for helicopters, such as Hovering Throttle and Pitch knobs, OFST, ACC, DELAY, and INVERT CROSS. You may use a mixer to adjust gyro sensitivity, or to enhance flight capabilities or to correct a response you dont like. Again, we recommend you set up and trim in the Normal flight condition before setting up the alternate flight modes.

To TRIM function Turn the INVERT function ON by pressing the (+) key ("ACT" displayed). Turn the function off with the (-) key ("INH" displayed). Both the inverted pitch curve (PI-CRV INVR) and inverted cross position ACT/INH display (INVERT CRSS) functions in the To PARA or SWASH (initially set to INH) Special Mix Menu can be activated function simultaneously.
The 8UH has digital trims which are different from conventional mechanical trim sliders. Each trim control is actually a two-direction switch. Each time the trim switch is pressed, the trim is changed a selected amount. When you hold the trim lever, the trim speed increases. The current trim position is graphically displayed on the screen. The Trim function includes a number of submenus that are used to manage the trim options. This may be better understood by viewing the menu structure on p. 20.
These keys are used to move through submenus in the TRIM function. To SUBTRM function Select the desired function in the TRIM submenu with the (>) and (<) CURSOR keys. "NEXT" indicates that there is a group of submenus in the TRIM function. TRIM functions: Trim Reset Trim Step Rate Trim Reverse Display

The Trim Step menu may be used to change the rate at which the trim moves when the trim lever is activated. It may be set to a value ranging from 1 to 40 units, depending on the characteristics of the aircraft. Most ordinary aircraft do well with their trim step rate set to about 2 to 10 units.

Copying from one model memory to another
These keys are used to move through submenus in the MODEL function. To TIMER function MODEL DATA COPY Select the destination model number with the (+) and (-) keys.

The NAME function may be used to assign the current model memory a name. The model name makes it a lot less confusing since you can easily tell your model memories apart. The name of the model that you assign is displayed at the top left corner of the startup screen. The name can be up to six characters long, and each of the characters may be alphanumeric, space, or symbols (see list below). The default names assigned by the factory are in the "A:MDL-01" (Model 01) form. Note that the model type is displayed as the single character that appears before the model name on the screen. The code used is H = HELI (helicopter), A = ACRO (aircraft), G = GLID (glider) Model Naming Instructions

The Timer Menu controls an electronic clock that may be used to keep track of time remaining in a competition task window, flying time on a full tank of fuel, amount of time on a battery, etc. The timers settings may be set independently for each model, and is automatically updated each time the model is changed. The timer can be set to count up to 59 minutes 59 seconds. You may choose either a count-down or count-up timer mode. When the timer switch is turned on, the down timer starts from the chosen time and displays the amount of time remaining. If the timer exceeds the time setting, it continues to count and displays a minus sign () in front of the numbers. The countup timer starts at 0 and displays the elapsed time. In either timer mode, the timer beeps once each minute. During the last ten seconds, theres a beep each second. The timer screen can be easily displayed or cleared by pressing the key at the startup screen when the transmitter power is turned on. The timer is started by the plus (+) key and stopped by the () key. When the "+" and "" keys are pressed simultaneously, the timer is reset. keys (+ and ) are pressed simultaneously after the timer is started, the timer is reset, If the but continues to count up or down. The starting and stopping switches may be chosen among any of Switch A Switch H, activated by the throttle stick (STK-3) , or activated by the power switch(POWER SW). The ON and OFF directions can also be freely selected except the power switch. Using the throttle stick is particularly convenient if youre keeping track of fuel remaining, or for an electric, how much battery is left. Regardless of which switch is chosen, the timer can also be turned on and off with the keys.

First, position the throttle stick so that it's in the location where you want to have the timer switch on and off. 2. Next, press both of the (+)/(-) keys simultaneously to make the transmitter memorize the location. 3. Now you'll choose which side of the set point is on, and which side is off. If you want to turn on the timer at the hight throttle stick position, press the (+) key. If you want to turn on the timer at the low throttle stick position, press the (-) key. After you choose the direction, an up or down arrow is displayed at the top (high) or bottom (low) side of "3" at the top right corner of the display, to confirm the switching direction you have chosen. Move the throttle stick back and forth to confirm that the timer starts and stops as desired.
Timer Switch Selection Select the desired switch location with the (+)/(-) keys. You may choose any of switches A-H, throttle stick(STK-3), or power switch (POWER SW). When you change switches, the chosen on/off directions are reset to NULL. If this is the case, be sure to choose the directions you want.

You can use Throttle Curve menus to program a five-point curve so that the engine speed responds the way you like relative to movement of the throttle stick. You can set each of the five points over a 0% to 100% range. There are three throttle curves: normal (NORM), idle-up 1 (IDL1), and idle-up 2 (IDL2). Only the basic normal throttle curve is displayed in the Basic Menu, but all the curves may be programmed in the Advance Menu. For your convenience, the normal curve can be programmed in either the Basic or Advance Menu, and it is automatically updated in both places. Switch G is programmed so that you may change between the normal (NORM), idle-up 1 (IDL1), and idle-up 2 (IDL2) curves.

4. Next, turn on the Flaperon function (FLPRON, p. 72) in the Advance Menu. To do this, press both ADVANCE buttons simultaneously, then press the MODE button until FLPRON appears in the display. Activate by key (ON should pressing the plus (+) appear flashing in the display.
2. Press the right (>) key twice to get to the model name function (NAME, p. 44). Use and keys to spell out the the name that you wish to appear on the screen, one letter at a time.
Connect the right aileron servo to receiver CH1 and the left aileron servo to receiver CH6. Note that you can get differential by adjusting the up and down motion of the two servos in the FLPRON menu. If you dont need the flap effect, you can use the AI-DIFF menu (and plug the servo into the receiver CH7 output. 5. Check that each servo moves the proper direction. The aileron servos should move in opposite directions for aileron stick motion, and the same direction for flap control. If not, use the Reversing function (REVERS, p. 33) in the Basic Menu to set the proper throw directions for each servo. Also check elevator, rudder, throttle, gear, and any other servos. 6. Set the basic travels with the ATV function in the Basic Menu (ATV, p. 29).
3. Enter the Parameter (PARA, p. 34) menu by pressing the down MODE key twice. Use the key to select the model type left (<) (TYP) function and verify that ACRO (aircraft) is selected. (If it isnt, select ACRO by pressing the keys until it appears, plus or minus then pressing both keys to select it.)
WARNING: selecting a different model type will erase the settings in the model memory. BE SURE youre in the correct model memory before selecting a new model type. If necessary, go to the modulation (MOD, p. 30) menu to select the proper mode of transmission (F is for FM/PPM transmission, and C is for PCM). This should be set to match your
Aileron settings: the left and right aileron travel should be limited to roughly 9/16 (14-15 mm). If necessary, adjust CH1 and CH6 with the ATV function. Choose a location on the servo arm so that the throw is adjusted in the 90-100% range. Elevator setting: adjust the elevator travel to roughly 9/16 (15 mm) with the ATV function.
Rudder setting: adjust the rudder travel to roughly 45 degrees in the left and right directions with the ATV function. 7. Dual Rate setting (D/R, p. 29) Adjust the servo motions with the D/R function (in the Basic menu).

The Flaperon mixing function uses two servos to individually control two ailerons, combining the aileron function with the flap function. For a flap effect, the ailerons can be raised and lowered simultaneously. Of course, aileron function, where the two controls move in different directions, is also CH6 CH1 performed. The up and down travel of the left and right ailerons can be adjusted independently, so you can also get a differential effect. Left and right flap travel can be adjusted individually. You can combine the Flaperon function with the airbrake function, to get steep descents without building up airspeed, which is very convenient for small or narrow fields. To take advantage of the flaperon mixing function, youll need to connect the right aileron servo to CH1 (AIL) and the left aileron servo to CH6 (FLP). NOTE: Only one of the three functions flaperon, aileron differential, or elevon can be used at a time. All three functions cannot be activated simultaneously. The last function activated overrides the others.

The Ailevator mixing function allows you to connect two servos to the receiver that operate two independent elevator control surfaces together as elevators and differentially as ailerons. This may be used to get more realistic flying properties with jet fighters and similar aircraft. You may also use this mixing to drive dual elevator servo without differential. The elevator and aileron travel can be adjusted independently. The two elevator servos must be plugged into the receiver CH2 and CH8 outputs. NOTE: Ailevator mixing cannot be activated simultaneously with the throttleneedle mixing function, because they use the same receiver channels.

We will first activate all the special mixes necessary, and later go to the reverse menu to correct any reversed servo responses (if necessary). buttons to get to the Advance Press the Menus. This is where are the sailplane-specific keys mixers are located. Press either of the to get to the aileron differential (AI-DIF) settings menu. Activate this mode by pressing the plus key (the symbol will be (+) flashing). This makes the second aileron servo (CH7) operate. Ignore the number settings for now.
Now you may choose whether you want this mix always on or switchable. By hitting the Right (>) key, you will see a display indicating Switch E controls this function, and the setting of the switch. NULL means always on, UP means on when Switch E is up, and DOWN means on when Switch E is down. We recommend leaving it in the NULL position; you can change the switch setting by pressing the (+) or () keys.
5. If your model has a V-tail, go to the V-TAIL menu (p. 75) and activate it. This will make the elevator and rudder commands mix to the two tail surfaces. Leave the settings as is for now. 6. Now move the aileron stick to the left. You should see your models servos deflect as shown in the rear view below. The Right aileron and flap should move down, and the Left aileron and flap should go up. If the wing servos move as specified, you can continue.

Reverse any of CH1, 5, 6, and 7 by moving to the appropriate channel number with the right or left keys, then pressing the minus () or Plus (+) key to reverse or unreverse the channel. Be sure you get the aileron response in the picture.
(this may be changed later for more travel). For cruising, you'll want no droop at all, but for slowspeed thermalling, you may want to droop the trailing edge a bit. Use the flap trim setting to get the desired amount of camber. No more that about 1/8" (3 mm) is all that is needed for most models.
Next, move the elevator stick and be sure that the elevator moves the correct directions. Reverse CH 2 if necessary. Similarly check the response of the rudder (CH4). If you have a V-tail, you should get the following response for rudder and elevator commands:
Note that the motion dictated by the Camber knob (CH. 6 flap trim knob) goes into both positive and negative camber from the neutral point, unless you set the FA offset (see previous step). Also, note that if you dont set a small number or leave it inhibited (its default condition), you get HUGE motion of the trailing edge. You can set the approximate neutral point by matching the notch on the front of the knob with the slot in the knob holder. 10. Put the camber knob (CH. 6 flap trim knob, on the top left of the transmitter) where you want it to be for normal flight, and make sure that the travel you desire is the right direction from that point. Be sure to center all of the trims, and get all of the servo arms to be near neutral. Use the clevises to get as close as you can. This way you won't run out of subtrim authority. Now set all the subtrims (SUBTRM, p. 40) to the desired neutral locations.

1. Turn the BFLY function ON by pressing the (+) key These keys are used to move through the ("ON" or "OFF" displayed depending on SW-A position). six submenus in the BFLY function. Turn off (INH) the function with the (-) key. To ELE-FL function (GLID1FLP) or FLP-AI (GLID2FLP)
Shows that switch A turns the BFLY function on and off.
Servo travel Range: -100 to +100% Initial value: 0%
Elevator delay value Range: 0 - 100% (Initial value = 0%)
Throttle stick position for BFLY begin: Range: 0 - 100% (Initial value: 0%) 6. Enter Throttle position The throttle position you set becomes the starting point for butterfly mixing. The servo motions increase linearly when the throttle stick passes this position towards "low throttle." Move the throttle stick to the desired butterfly on/off position. Enter the position into memory by pressing the (+)/(-) keys simultaneously.
Flapaileron mixing is used to change the camber (the angle of the ailerons and flaps) over the entire wing, which produces less drag than just dropping the flaps by themselves. When you have ElevatorFlap mixing activated along with FlapAileron mixing, the entire trailing edge droops or reflexes with elevator stick motion. You can program an offset of the flaps as described in step 3 below, but we suggest leaving this at zero initially. Switch "D" is programmed to turn this function on and off, but you can have the function always on if you like by selecting the NULL direction.

Setting up FlapAileron mixing
1. Turn the FLP>AI function ON or OFF by pressing the (+) key ("ON" or "OFF" displayed depending on switch D's position). Turn off (INH) the function with the (-) key. These keys are used to move To AI-FLP through the four submenus in the FLP-AI function. function

Flap neutral position
2. Aileron travel rate setting Adjust the amount of aileron travel compared to flap motion with the (+)/(-) keys. If you're unhappy with what you've set, you may return to the default value by pressing the (+) and (-) keys simultaneously. 3. Flap neutral position offset Turn the CH6 knob in the desired offset direction. Memorize the amount of offset by pressing the (+)/(-) keys simultaneously. (Suggest leaving 0% initially)
