- This is the same chassis I've been running without problems.
- I've installed a rebuilt gear diff and it has an adequate amount of side to side play.
- The motor plate is the v.1. I'm testing to see if it runs any smoother than my v.2 when it gets warm.
- New bearings. Properly seated.
It seems as if the chassis is twisting very slightly when these screws are in place. Even the carbon shock tower seems to pull the chassis halves together just enough to create friction. I'm thinking about using a 0.3mm shim between the chassis halves. Opinions?
I'm pretty sure there is some differences (besides the offset) in the V.1 vs the V.2 motor mount where the gear shaft seat into it. That is probably why the V.2 also calls out for that spacer.
I would compare the 2 motor mounts side by side and see how the gear shafts seat in.
