16. Trimming the quadrocopter
If you find out while flying that the quadrocopter wants to fly laterally to the left or to the right or to the front or the back
without control command from the transmitter, correct the flight behaviour with the trimming.
If you have secure control of the quadrocopter, you can adjust the trim during the flight. Then you can clearly see how
the quadrocopter responds to the changed trim setting. If you are not quite sure, you can land the quadrocopter and
then adjust the trim. In this case, you will see if the trim setting is sufficient after the model takes off again.
Every time a trim button is pushed, the trim is adjusted by one step and the adjustment confirmed by a short
beep. In addition, the two LEDs on the transmitter go off briefly and on again.
When the button is pressed and held, the transmitter emits a quick sequence of beeps, and thus indicates
the step-by-step adjustment of the trim. The two transmitter LEDs flash when the trim buttons are pressed
and held.
Once the trim's end position has been reached, the transmitter will stop beeping.
The trim's centre position is indicated acoustically by a longer beep.
Roll trimming:
If you want to drift the quadrocopter to the right laterally (see dark arrows in Figure 14), press the push button for roll
trimming to the left several times (see also Figure 1, no. 6).
If you want to drift the quadrocopter to the left laterally (see light arrows in Figure 14), press the push button for roll
trimming to the right several times (see also Figure 1, no. 5).
