Power Plant Question
Can someone explain to me the physics behind why when you have less "turns" in a motor it can spin faster? I understand why when more wires are used, it becomes smoother, but not so much the motor turns in relation to RPM.

Short answer: Higher current draw, higher magnetic field strength of the stator [or rotor in a brushed motor], stronger opposing force reaction with the permanent magnet in the motor, more rotational speed.
As long as the ESC can switch phases fast enough, [or the brushes can maintain contact with the comm in a brushed motor] you'll get more RPM.
