Sure, if you are setting up the driveline in you hotrod. I don't see why not. It is basically the same principle, you use it for setting up the driveline in a vehicle to make sure everything is at the proper angles to each other just as you do with the surfaces of a plane. I don't know of any metal surface it would stick to on an rc plane but it will let you know the differance in degrees of the two wings. I cannot testify to the accuracy that it will give you on a plane.
