Adjusting rudders

Open the Servo > Calibrate > 2: Rudder menu.
1.
2. Open the REV/TRM parameter and set rudder travel to the left.
If the rudder does not move to the left, reverse the servo using the
REV/CLR button.
3. Move the control surface to the neutral position using the central wheel or the
+ / – buttons.
The setting range is +/-10%. Offsets exceeding 5% should be corrected
mechanically.
4. Correct the maximum servo travels using P1 and P5 so that no mechanical
stop is reached (see section 7.1.3.2 "Adjusting control surface travel and
maximum servo travel" on page 184).

Adjusting flaps

1. If your model has inboard flaps perform step 1 to 4 in section 7.1.3.1
"Configuring aileron differential" on page 184 for the inboard flaps.
2. If your model features mechanical airbrakes, extend them using the assigned
control. Check and correct the actuation direction in the Servo > Calibrate
menu for servos 8 and 9.

Adjusting the power system

1. If your model has a power system, check the actuation direction of the throttle
channel.
2. If required, adjust the rotation direction using the REV/CLR button.
After these steps, the main setup is completed:

The control surfaces move in the correct direction.

Maximum travels and neutral positions are adjusted.

The ailerons move synchronously.

Using ailerons as spoilers

To raise the ailerons as airbrakes (spoilers) proceed as follows:
Open the Mixer > AILERONS+ menu.
