11. Calibration of position sensors
If the quadrocopter does not hover steadily in one spot but is always flying in one direction, the trim may need correct
-
ing. However, if the trim needs to be adjusted significantly, it may be necessary to re-calibrate the position sensors
in the model.
Proceed as follows:
First switch on the quadrocopter and then the transmitter.
The trims must all be set to the middle position.
Place the quadrocopter on a flat, horizontal surface.
Then move the two joysticks of the transmitter (see also
Figure 1, no. 4 and 12) to the lower right corner and hold
them in this position.
You can see a flashing LED through a small opening on
the left or right rotor arm (1). If the LED no longer emits
flashing pulses after approx. 1.5 seconds, the calibration is
successfully completed.
Then pull the joysticks back to the middle position.
Check with a test flight whether the quadrocopter is still
showing a strong tendency to fly in a particular direction.
Small tendencies can be offset by trimming. If required,
repeat the calibration process.
Attention important!
After a clumsy landing or a crash, the quadro-
copter cannot be started for approx. 10 sec-
onds. During this time, the position sensors are
automatically recalibrated. This process can be
shortened by manual calibration.
