16. Troubleshooting
16.1 Problems/Solutions
Problem
The model does not respond.
The remote control does not respond.
The remote control turns off straight away or
after a short period.
The model vibrates when the motors are
running.
The model does not fly straight in stabilisation
mode.
16.2 Resetting the gyroscope
The built-in gyroscope is required to ensure that the model flies in a straight line. If the default settings are changed
for any reason, the gyroscope must be reset as follows:
Prerequisites: The flight battery is connected and the remote control is switched on and ready for use.
1. Place the model in a completely horizontal position.
2. Press and hold the reset button (R13) for 2 seconds.
3. The gyroscope is now reset.
16.3 Re-establishing remote control/receiver connection
The remote control and receiver are preconfigured during production.
Only perform these steps if the model stops responding to remote control commands.
To re-establish the connection, follow the steps below:
1. If the remote control is switched on, switch it off using the on/off switch (R2) and disconnect the flight battery.
2. Secure the model in place. The propellers must be able to turn freely in the event that the motors turn unexpect-
edly, but the model must not be able to take off.
