Don't alter these settings unless the model is on the ground.
Always stop the motor before making any changes.
§
Set the collective pitch stick to the minimum position:
Set minimum throttle by adjusting the trim slider adjacent to the collective
pitch stick.
§
Move the collective pitch stick to the hover position (centre):
If the throttle setting is not correct for hovering, adjust the centre point of the
throttle servo 5 (SERVO menu).
§
The model should climb, with no change in rotational speed. The carburettor
should be fully open, the motor producing maximum power. If rotational speed
falls during the climb, you need to reduce the maximum collective pitch value.

b) Adjusting tail rotor compensation
Static tail rotor compensation can only be set correctly once you have set up the
correct relationship between throttle and collective pitch, i.e. the system rotational
speed is approximately constant over the full range of collective pitch.
The first step is to set the compensation for the positive collective pitch range
(climb). Place the model in a hover, then move it into a brisk climb. The tail boom
should swing as little as possible away from its proper heading when you carry out
this manoeuvre.
Any corrections are made in the menu point T-ROT CP (tail rotor
compensation for the positive collective pitch range) within the
MIX menu. You can set any value (range –99% to +99%).
The next step is to set the compensation for a descent. Place the helicopter in a
climb, then move it into a rapid descent. The tail boom should not swing round
during this manoeuvre.
Any corrections are made in the menu point T-ROT CP- (tail rotor
compensation for the negative collective pitch range) within the
MIX menu. You can set any value (range –99% to +99%.
