Reedy Blackbox 410R & Reedy Sonic 7.5T Motor. Combo was removed because either motor or esc was not working properly. The leds on the esc were signaling low voltage cut off was activated even with a charged battery. I swapped the sensor wire still no luck. I was heloing someone fix the car a just replaced the combo with a hobbywing setup so not sure on the history. I dont have the blackbox to check what voltage cutoff was at or also wasn't able to update firmware, so hard to say either esc of motor is bad, i feel its the esc that wasnt working right but the combo is being listed for parts or repair because of the problem.
