Since I have cripple person problems, I can't use the mavic pro controller.  However, I can use a xbox one controller with one hand no problem.  Do any of you think or know if it is possible in any way to forward an xbox controller's signal to a mavic controller, then to the drone?

I prefer to use everything as effectively as possible and having to use the original controller well... would be a pain.

Nah, I don't thinks so

Hello and good day Th3RadMan. Thank you for reaching out and for the inquiry. I am sorry to say that you can not use the xbox controller to operate the DJI Mavic Pro due to it's hardware and programming differences. Thank you for your valued support.

still need help about that?
you can gut the mavic controller, and solder its motherboard inputs to, xbx controller inputs.  that should do. alternatively, if you can work hand in hand with arduino, you can build a transmiter, that fits into xbox controller chasse.
