Simple Transmitter Setup – Aerobatic Airplane (ACRO)

Press the Up or Down

arrow keys to the Flap Trim

function (FLPT), and input

a percentage of FLPT value

using the Data -Decrease

key(default is 30).

This temporarily disables the flap knob (VR1) so that you can

set aileron neutrals without regard to the flap knob position.

Later we’ll turn it back on.

24. Before we set the servo neutrals, we need to be sure

that all the trims are centered. Press both Edit keys to get

to the main menu, where voltage and time are displayed.

Press the Up arrow until the word TRIM appears.

By moving each of the four trim levers around, you can

see their positions, and move them back to zero for the

next step.

25. Once you have centered all the trims, unscrew the

screws holding the servo arms onto the elevator, aileron,

and rudder (we’ll set the throttle travel later). You will

want to place the servo arms on the output shaft so they

are near neutral - that is, about 90 to

the servo case sides or, if the servo is

mounted sideways, 90 to the pushrod

(sideways mounting is not recommended)

This way you won’t run out of subtrim

authority. Remove

all the arms that are in the way or

interfere with your pushrods.

If the rudder moves in the wrong direction, move over to

Channel 4 by pressing the Cursor Right key. Now the

‘4’ should be flashing in the display. Activate the opposite

direction for the rudder servo by pressing the Active/

Inhibit (Clear) key. Move the left-hand stick left-and right

again and verify the rudder moves the right direction.

If your model has retracts, set the correct response direction

when commanded by the Gear switch, using the

same procedure. If you’re using a second aileron servo,

you’ll now set the left aileron servo direction (otherwise skip

this and the next step). This is channel 6, and the ‘6’

should be flashing for this command. When you move

the right-hand stick to the right, the aileron on the left wing

should move downwards. Check that the left aileron

moves the correct way! If it does not, activate the opposite

direction for the left aileron servo using the above

procedures. Move the right-hand stick again and verify

the left aileron moves in the proper directions.

Adjust the clevises on each servo pushrod to get the

position of each control to be as close as you can to

neutral (lined up with the adjacent portion of wing or tail).

Setting Subtrims. Now

we’ll adjust all the subtrims

to electronically set the

desired neutral locations.

To do so, go back to the

programming menu by pressing both Edit keys, then

press the Up or Down arrow key repeatedly until STRM

appears.

26. Set the right aileron subtrim first. If the channel 1 is not

flashing, press one of the Cursor

Left or Right buttons until it is (see figure). Then, adjust

the subtrim amount by adding or subtracting with the

Data +Increase or -Decrease keys. When you reach a

place where the right aileron matches up with the fixed

portion of the wing, you are done. If you can’t get both

to match up, then set the subtrim back to zero and

mechanically adjust the clevis to get as close as you can,

then readjust the subtrim if necessary.

27. Note 1: you should NOT use subtrims instead of

mechanically adjusting the pushrods to be close. This

is because you can reduce the travel of the servo, especially

if you have to set the subtrim near 100%. As we

stated before, get the pushrods close mechanically first,

then use the subtrim adjustment to get it just right.

28. Note 2: if you mess up the number you’ve entered

or find the percentage the wrong direction, you can get

back to zero quickly by pressing the Active/Inhibit

(Clear) button.

29. Repeat the subtrim

adjustment with the elevator

servo (CH2). First set

the pushrod length mechanically

to get as close to neutral as

possible, then set the subtrim to

get the elevator lined up to be parallel with the

stabilizer portion. For full-flying surfaces, use an incidence

meter or another method to get the incidence angle

recommended by the kit manufacturer or model designer.

30. For the throttle, we recommend not setting a subtrim

at this time. You will use the trim tab on the transmitter

for setting your idle RPM. To shut off the motor you will

use the Engine Cut function. In this way, you don’t lose

your carefully-set idle position.

31. Most people set up their engines to idle with the

throttle trim near center, so that there is room for changes

due to humidity and other factors.

32. The Eclipse 7 Pro provides a special throttle trim function

which allows the throttle trim lever to work at low throttle

levels, but disables it at high throttle.

33. Repeat the subtrim adjustment with the rudder (CH4),

gear (CH5), 2nd aileron channel (CH6), and the CH7

function if used. As before, first set them mechanically,

then adjust the electronic settings. Be sure you have

selected the appropriate channel number each time.
