Guys when you get out of the throttle and go to the brake. there is a grinding (sounds like a gear being stripped) When I put the mamba on it got exponentially worse. I am sure it is due to the extra braking the motor is doing on the spur and the rest of the drive train. It is not damaging the spur, I have checked. And no damage to the pinion ( a robinson 15t). So it is the 60t spur (comes standard on the MT) and a 15t pinion on a 5400 kv mamba.
Anyway I think this grinding is from in the differentials. Is this correct?? Is this doing damage?? or is this the diff balls inside the diff ball tube and its normal??
I haven't torn into a diff yet. but my understanding is that the diff balls replace the spiders and just kind of lock up inside to provide a gearing effect.
