can you use a single esc to run 2 motors?
lets say you have 2 10A brushless motors and a 20A ESC. can you use the single ESC to run both motors?

No problem with dc (brushed) motors but ac/3 phase (brushless) might not start up if not exactly the same.
So if you want to try you must use 2 exactly the same motors and props.
The reason is that the coil that will be powered by the esc is "decided" after measuring the location of the magnets.
It can only do that for one motor so if the other "gets behind" when turning (and when starting) the wrong coil in that motor will be powered and then the motor will shake back and forth but not rotate.

I've done it, sometimes it works no problem and others you have to play with the throttle a couple of times to get the motors to sync/start up together. Once your flying they go no problem.
