9. Calibrating the gyro
In case you should experience a strong drift of your Nano to
any side when flying and the trim-function cannot compen-
sate for this behaviour, you should calibrate the gyroscope
of your Nano. To do so, proceed as follows:
- Put the Nano on a smooth, even surface
- Make the Nano ready for take-off (pls. see 2. Starting the
Gravit Nano)
- Then completetly deflect the left control stick towards lower left and the right control
stick to upper left at the same time.
If you succeeded, then one red and one blue LED on one of the Nano’s sides
should flash up shortly. The calibration process is finished and the Nano should fly
again normally.
10. Safety cut-off
In specific situations (for example after a hard landing or if one or more rotors are blo-
cked), the Nano might power off itself and then cannot be powered on again using
the On/Off-switch. Should this happen, please do as follows:
- Switch OFF the Nano -> Switch to the right position (if looked from behind)
- Connect the Nano to the USB-charger (which must connected to a 5V power-source)
- Disconnect the Nano after a few seconds
Now you should be able to switch on the Nano as normal and fly it again.
