Default Driving brush-less compressor and fan motors??

If you find a mini-split with a burned out controller board, could you
get the motors to run with hacked model airplane speed controllers?

In recent years, RC model airplanes have been using brush-less motors.
I know hardly anything about this type of motor, but I'm wondering
if there is any possible way to use an RC model ESC (Electronic Speed Controller)
to control larger brush-less motors? Maybe adding some power FETs to the
3 motor drive wires? Inserting more amps and volts.?.

ESCs are controlled the same as airplane servos, with a simple TTL pulse.
The length of the pulse is what sets the speed.
Maybe a simple micro controller could be used to simulate the OEM mini-split controller.?.


Ideas??
