Being new and still on the simulator for the FPV world, I am thinking of the FPV combo deals for the GPS, panic button, RTH button, etc.... I don't care for the Avata because of the motion controller. The FPV comes with the goggles, drone and controller. Since I plan on more drones in the future, I know the goggles can be used, but can the controller be used (bind) to other receivers in the future?
