Bob trimming:
If the quadrocopter drifts forwards, slowly reduce the flight altitude until the quadrocopter is safely back on its landing
feet. Repeatedly press the lower "B" trim button for the bob function.
Then, carefully push the pitch joystick forwards again and check whether the adjustment was sufficient. Repeat the
procedure until the model does not drift forwards.
If the quadrocopter drifts to the rear, press the upper "F" trim button for the bob function.
The trim for the bob and roll functions is not saved. After you switch the transmitter on and off, the trim
returns to the centre position.
When you have the quadrocopter securely under control again, you can adjust the trim to the required value during
flight.
Attention!
If large adjustments need to be made to the trim, the position sensors require calibration. This procedure is
described in a separate section of these instructions.
