Yep, I could blow the rear diff in a single run.
I was using the Hotbodies 1/8 diffs in the RCM Revo diffs cases. Was even using the aluminum 1/8th diff cup to eliminate flex at that point.
The setup was shoving a ton of abuse at the rear diff. The weak point was the pinion bearings. I even upgraded to the ceramic bearings. Didn't make a difference.
The spiral cut gears load the pinion ball bearings as if they are thrust bearings. It would punch the center race through the bearing every time.
Little balls everywhere. LOL
The 13/43 straight cut gears proved to be the tougher setup since they load the ball bearings the way they are meant to be loaded.
