One esc two motors

[Serum]

It can be done, as long as they are 1:1 mechanically connected. (thru gears or something)

You can position the rotor by using a small DC power supply or a mild power delivering battery (no 20 cells GP3700's) and connect them to two of the wires of the motor, do the same with the other, and the rotor is positioning itself into the right position. As long as they are equal.
