I've checked and checked my pinion and spur mesh but no matter how i set the mesh it still doesn't quiet it down.

I made sure that the diff bolt was backed off 1/8 turn from full compression.

Any thoughts, or is the gear diff simply that quiet.

I can't believe how fast the RTR is compared to my 13.5...
Everytime I do a diff rebuild I replace the main diff gear and idle gear. Every two rebuilds I replace the topshaft. I also place four dabs of white lithium grease on the teeth of diff gear. Another thing to check would be the straightness of the motor plate.
