
For electric helicopters: disconnect the motor!

Move the collective pitch stick approximately to the centre position.

Then, switch the receive system ON.
Start with the Collective function!
If the swashplate responds correctly when you move the collective pitch stick and if
the main rotor servos are connected correctly, the directions of travel for aileron and
elevator must also be correct.
To perform the check move the collective pitch stick in the direction of maximum
collective pitch (climbing) and observe if the swashplate moves up and remains
horizontal.
Changing the rotation direction
Open the Servo main menu.
1.
2. Open the Calibrate menu.
3. Select a servo.
4. Select REV/TRM and open the parameter.
5. Adjust the direction of servo rotation using the REV/CLR button. The effect of
the change is immediately visible in the graph (the curve reverses).
6. If the rotation direction is correct, confirm the change and exit the menu.
7. Select the next servo to be edited.
Make sure that the rotation direction for all the servos is correct before you start
to set travel and centre. If the rotation direction is changed later, a re-calibration
is required.

Calibrating servos: setting centre and maximum travel

Use the Servo > Calibrate menu (see page 146) to adjust the travels (P1 and
P5) and the centres (P3) for all the servos so that the servos assume the correct
idle position, move evenly across their range of travel, and reach the appropriate
end-travels.
