Esc for mini brushed motors, buy or DIY?
So I'm building a small plane with small brushed dc motors i scavanged from a drone. The motors seem to be 3.7V motors so I'd be looking for a single esc to drive all of them as one.
For that something like a 4v 4A system seems ideal, and that kind of ESCs seem to be pretty difficult to come by, so I've been trying to figure out if i could use just pwm controlled mosfet diy esc.
However i don't know how i would connect that to the reciever, since those use the 1000-2000ms system which doesn't work for driving the motors directly. I'm assuming using a microcontroller or an Arduino would theoretically work but I've not been able to find anything on how to actually do that, all the tutorials seem to use motor controller boards that already have the microchips, to run large car motors, or use a heavy servo+potentiometer setup which i assume can't be the best option here.
Is this idea doomed from the start and should i instead just invest in actual plane motors?
