If the helicopter is trying to drift forwards, cut back the speed and gradually move the nod function trim slider to the
back. Push the gas / pitch lever carefully forward and check if the adjustment was sufficient. Repeat the procedure
until the model does not show any tendency to drift forward. If the helicopter wants to drift backward, carry out a trim
adjustment forward.

l) Practical tips for the first hover flights
Your model helicopter is now ready for the first thorough test flights and you can start training. However, even with
flight training, you should definitely keep in mind some basic things.
•
For hover flight training, the tail of the helicopter must always point in your direction.
• To start, lift the helicopter approx. 20 – 30 cm from the ground, in order to be able to have it touch down quickly in
case of an emergency landing.
• In case of an emergency landing, do not retract the gas / pitch lever too quickly, as the helicopter will touch down very
hard and the main rotor blades may hit the tail tube.
• If the rotors are blocked by an obstacle, then pull the gas / pitch lever immediately into the lowest position in order to
switch off the motor.
• At the start location, draw a mark on the ground and try holding the helicopter hovering over the mark.
Note!
If you notice after a few minutes that the engine performance of your electronic helicopter declines,
cease operation immediately. Then leave the flight battery to cool down and charge it afterwards. Avoid,
in any case, a total discharge of the flight battery.
If after a few flights you develop a bit more feel for your helicopter, you can carry out further optimizations.
