build a gmaxx and i need help

[JoFreak]

no, only between the hybridbulks and the diffs, I only had to shim the piniongears.
as for bashing: no idea if the gorilla or FLM is better, I like the looks and layout of the G4 better, so I would choose it, or so I did but it was a G3 back then...
if you take the traxxas diffs you should probably go to use the stock bulkheads so it doesn't get a too big a loss if you decide to get some hybridbulks later ;)

if money isn't that a big issue for you, go for the hybrid bulks and the HB diffs form mike's shop and stop worrying...
