The rest of the answer would be to run the FPs with a speed controller. Speed controllers send 12V pulses to the motor, and through software, you control how long the pulse is on vs. how long it's off. As I recall, 128 or 127 is software is zero duty cycle, or off. 255 or 0 is full on in one direction or another. Soo... in programming, if you limit yourself to a range of 64-192 it's similar to limiting the voltage of the motor to 6V. It's not exactly the same, and the motor will be slower and less powerful and more likely to stall.... but if it does stall, you're only pulsing 12V to it 50% of the time, so it's less likely to overheat.
