im in the process of building my cgm right now and was wondering, how can make the drive train spin smoother? i have built it according to the manual already, but im not too happy with how it spins.

close to B... I always hated playing with rebound... that's what springs are for, not bladders.

I try to have the slowest possible rebound without having any bubbles in the shock. I find yokomo shocks being a pain to bleed properly.

If anybody's ever built Mugen onroad shocks, they should know what I'm talking about!

None of the above - I have them so they rebound slowly about half way.

I don't use the foam chunks above the bladder - I think they make the rebound artificially fast.

Make sure the input gears are firmly seated on the input shafts (they may need a little tap with a hammer to go fully home).

Don't tighten the spur gear holder so it's right against the bearings - make sure the assembly spins freely.

Run the car with the suggested shimming for a few runs, to bed the gears in. Then play with the shims to get a free spinning drivetrain, with a little backlash in the bevel gears. Personally, I'm running 2 shims on the input gear, and both the diff shims on the opposite side to the gear.

You should clean the bearings out, they usually come with a very thick grease... Clean this out and put something thinner in (Check out this forum for some good bearing oils.)

Same here... my shocks only rebound halfway too... The bladders are still pushing them a bit.
