Hey all (and Paul),
I know you know me
and nope I didn't clean the motor up, new brushes etc before hand....but it was freshly skimmed and the brushes were cleaned up real good.
The cells were fully charged, GP4300's - been fine on everything else I've run.
Checked the servo hard by applying resistance to the arm when it was moving. You know, held it and tried to make it slip...but couldn't do it...it pushed against me all the time in both directions. Servo seems ok from my testing in non-race conditions around my living room and outdoors on the road with a different motor.
Checked all the other possibilities, like the servo arm slipping, the steering arm, the ball-cup threads (XX4 has some on the steering arm from the servo and they were holding and not stripped).
It's weird cos it really seems to be this particular motor, which now has a totally split brush wire.
I just wanted to know if a partially split brush wire could cause this weirdness? Could this happen??
I'll put some new brushes on it soon and see if it does the same thing anyway...and report back of course.
Cheers.
