I'm in the process of crash repairs for a recent tip-over. While putting the main shaft back and getting it to the point where I can spin up the motor I noticed something weird. Just to put things into perspective I have the motor pinion not to tightly seated with the main gear (not too much play and not too tight on the high ends). After spinning up and killing the throttle I now try to spin the main gear by hand (in the right direction of course) and it seems stiff or needing a lot more effort to spin the gear by hand.
Now when I disengage the battery pack the gear spins freely like I would expect with little effort. It seems the motor is applying some electromechanical resistance. When I connect the pack again, initially there is no resistance in the main gear spin (by hand), I throttle up for a couple of seconds, kill the throttle and the resistance is back, disengage the power supply and resistance is gone.
Is this common? If so I didn't notice this previously.
Thoughts?
