The Elios and Elios 2 drones use DJI Lightbridge 2 control units, and as such require the DJI GO app to be used for some advanced operations such as:
- Changing the master/slave setting
- Calibrating the control sticks
- Setting up the HDMI output
- Troubleshooting the the control unit
Flyability drones require firmware v1.2.10 to be installed on the control unit, it is therefore imperative that you do not let the DJI GO app perform a firmware update, even if it shows a flashing banner:
Performing this anyway will install version 1.2.40 or higher, leaving the drone unable to connect to the controller. It is not possible to downgrade from this.
