Not sure that is the case. As the cost of a motor goes down, so too does the production controls. There are variances motor to motor. Two motors linked in a common gearbox will run together since there is no other way for them to run. You need to feed the same values to each controller to insure that the motors share the load.

BTW, two FP motors connected to a single speed controller would exceed the max current of the controller when the motors are at stall.
