I called Kyosho on that and they agreed LOL. The "proper" way to install the shock bushing is to use the 4.8mm and crush them, but I see that as a little errrr queer at best. I'm gonna use the 5.8s I have and cut them to the same size.

First race meet with the RB6, team japan setup with pink/red, changed to pink/gold and ifmar pins and the buggy was a dream to drive.

I notice that it tends to nosedive a bit. Nothing wrong with that, but didn't expect it on the first jump, dug the nose into the dirt and had to fight my way back from last to 2nd. I also notice that with my current setup (team japan, pink/gold, 35/30 oil, silver losi wide ribs/red pins) steering is good under power but if i let off a bit and the weight transfers back to the front, the fronts grab a bit and the rear gets a bit loose.

I'm going to fiddle with the shocks a bit, currently on 35/30wt f/r, might change to 40/35 or 40/40 as the rear is still a bit bouncy on my bumpy track. Any comments on slowing down the rear?

Finished mine over the weekend. The plastic battery posts with clips just irked me, so yesterday morning I modified the battery holder to accept my aluminum posts. Since I am running the standard lipo, I have a spare battery holder just in case I need to go back

Starting with the Japan setup with two minor changes. 0 degrees in the caster block (instead of 4) and .5 degree rear hubs (instead of 0).
