quick Neu motor question

[rschoi_75]

MM on mine. and yes, i'm running a hardened metal pinion/spur combo on my jammin cr.

Its not the slow beep that feigaos give off. its closer to a very loud clicking. It happens only at the very start or at the very end when the car free rolls to a stop (no brake applied). The motor rolls freely when the rpms are high, then gets "stiffer" after falling below a certain rpm threshold. The sound comes from the friction between the pinion and spur when the motor "stiffens" up. That's why I was assuming its the magnets. Not sure if my reasoning is correct, so I wanted to get some opinions.
