I just discovered Flite Test and my son is excited about building and flying RC planes. He has a DJI Phantom 3 Standard. It is possible to use Ph3 controller with another receiver for 3 or 4 channel flight on an FT Mini Tiny Trainer or Ft Explorer?
I am unsure how transferable DJI gear is as it is very proprietary stuff. One would assume that you could pair it to another DJI receiver and set up another model. I am not however sure if DJI has more then one model memory or not. That would be the limitation if there was any I would think.
