I'd be glad to give it a try.   I've fixed a vibrator or two in the past.  😸

That Explains your chipped teeth and your chapstick addiction!

But they also do it to control heat.

Heat shouldn't become an issue until the battery (s) get low and Voltage drops, and I'm not sure that even THAT matters with Li power sources that deliver steady voltage until they go dead. Just like in a cordless drill, once voltage drops below a certain level a self-resetting breaker shuts the juice off until the circuit cools back down, to prevent a meltdown.  Nevertheless all motors and control units that are covered by a cowling, or buried under upholstery ( affecting heat dissipation) are cooled by lake water in the same fashion that fuel combustion engines are.  

No different than a drone.....except there's more of a load on the motor.

What I think they need to scrap and forget about is controlling ANYTHING by RF signals.     You're just begging for trouble, and it costs more to build that way.  

Forget that crap and stay with mechanical cables and/or wire harnesses that you CAN SEE and TOUCH !   

With a drone or little dune buggy you need that......but if you're actually riding in the craft YOU DON'T.......So why add a system that can potentially fail or be jammed?

The way resistors work is the reduce the flow of electricity. That reduction causes heat in the resistor. You aren't really just turning down the power, you are converting it into something else, which in that case is heat. That's just wasted energy unless you are creating a heater. So yes you can cool it and control it but it's still energy lost to heat at that point. Lot's of electronic things work by supplying energy in frequencies these days.

See I told you engineers would ruin it!
