@skyveyor @malex_sky From previous DJI to Pixhawk conversions … the DJI ESC plugs straight into the pixhawk motor inputs.
I’ve had success with DJI E1200 propulsion system running with Pixhawk 2 Flight Controller. So I think this would be the same for the M600 propulsion system.
I would think you could strip out the lightbridge connection but still use the 2 2.4GHz antennas for the receive system (might have to modify the connectors). That should give you basic control of the M600.
Video and other bits and pieces is another story.
Not too complicated … just need time to do it.
