How quiet is your transmisson? I know that is tough to say, but my brother bought a b4.1 Ready to Run, which has the gear diff and it is so quiet compared to my worlds car. I just built the car in august but i took the transmission apart to inspect and clean it. It did quiet down some but still not close to the rtr.

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...
