Everything old is new again?? We used to do this sort of thing, many years ago before ESCs were as good as they are now (small, light, fairly inexpensive, good BECs and other features).

For 15 or 20A you can get away with a setup like that for some time. Sooner or later the switch will die. Been there, done that.

At 50A I'm surprised the switch doesn't weld itself together in the on position the first time you use it. A switch that's big enough to actually take that load and switch it safely (remember you WILL be switching the startup current of the motor) is large, heavy, and not cheap.
