13. Calibrating the position sensors
Before starting the quadrocopter, you should calibrate the position sensors. This ensures that the quadrocopter hovers
smoothly at one spot and does not fly in one direction spontaneously and without a control command.
Proceed as follows:
Place the ready-to-fly quadrocopter on a flat, horizontal surface.
First switch on the quadrocopter and then the transmitter. Move the left joystick back and forth to get the quadrocopter
ready to start.
The LEDs on the quadrocopter and the transmitter must glow steadily.
Then move the left joystick (see also Figure 1, no. 13) to
the lower right and the right joystick (see also Figure 1, no.
4) to the lower left.
Hold the two joysticks in this position.
The transmitter emits one beep and the transmitter LEDs
flash twice. At the same time, the LEDs on the quadrocop
-
ter begin to flicker.
When the LEDs on the quadrocopter light up again, the
calibration is complete and the joysticks can be moved
back to the centre position.
