In regards to joystick users, specifically to Android users. I have now tested a proof of concept. For those of us that would like to do long hauls as well as use a joystick. If your device allows for wireless charging, a 5 watt charger and above will do the trick for long hauls. Simply place your device on a wireless charger while flying and it will maintain a charge throughout the flight.
Warning: It is reccomended that you keep scenic on as well as brightness down as wireless charging can heat your device up.
