What truggy as a basher?

Dont use any of the small orings. Make sure you use lots of grease on the out drives, o'rings, shim's. Mugen diffs are tight from the start and will meed a tank or two to break in. So tight in fact that if you don't use enough grease out drives will seize in cup or ring gear from the heat build up. Good grease is very important. Use a red high temp moly based grease like the Mobile 1 stuff Chad showed you.
That crunchy will go away in a tank or two.
