GorillaMaxx GR3 Help needed

[Serum]

do the slots in the drivecups bind with the crosspins or does the round part of the bone bind?

With the earlier edition of the revo you needed to mount up the bulks to the plates first, and then mount it onto the chassis. And yes, there was tension in them.

It's not a perfect 1:1 bolton/fit. It needs some attention.

The front lines up perfectly, but the rear was more of a puzzle. My guess is that if your lower skid was bend it would have been less of a problem. The kickup is actually the other way around, it's more of a kick-down
