This past Saturday, I had some motor problems while racing my old RC10T. During the first qualifier my motor stopped working right and got very stinky and even let off a very little bit of smoke. I thought it might be a COMM problem, because it was an old stock motor that had never been trued. Since I planned on getting a new motor this week anyway, I decided to just go buy it then. I bought a Trinity Green Machine 3 Pro. Since the capacitors were already installed, I soldered on a Schottkey Diode (yes, the polarity was right) and my motor wires and raced the next qualifier. All was well (it really was fast) until the end of the race. I noticed some serious smoke coming from my brand new motor. Aaahhh! I turned my equipment off, and let it sit while I watched the next race. Then I turned it on and yanked the trigger a couple times; smoke immediately bellowed out of the motor again. It had a good 6-7 minute rest, so I was surprised it smoked again. I checked the motor and it had not seized; there was nothing foreign stuck in it. I asked a couple guys what they thought and they said I probably overgeared it, but that seemed improbable (I used the same 20 tooth pinion, even when the GM3 instructions said go up a tooth or two). Then another friend checked my diff. It was in terrible shape; it made serious noise when spinning the balls. So we rebuilt it. Note: I avoided rebuilding it for months because I was getting a new truck anyway. For the main, I used my old motor again (just in case) and all was well -- almost. It seemed to lose power halfway through the main (I thought maybe the motor was slipping away from the spur...but it was still tight after the race) and the motor was a bit stinky after the race again, but the problem definitely wasn't my brand new Reedy WC Zappers (Sanyo 2400s). It could've been my crappy, old, worn-out comm, but I don't know. Do you think my assumptions were correct? Could this be caused at all by my Tempest ESC? What do you think about this?
