Its not the diffs tho. Bearings, axle shaft and a new set of wheels so far... I need to buy a couple more parts for it. It will either work out or it won't. I'm not going to stress over it too much.
I bought it to bash but it doesn't want bash without breaking. For my purposes, thats useless.
I already money pit cars. The Granite will never become that for me. If it won't bash as it was designed, I'll sell it and buy one that does.
I bought this truck so I WOULDN'T have to bash my race buggies.
I don't want to put money (or time) into a truck that gets hammered in my back yard.
There are lots of RC's out there that can run 3s all day and not have drama. THAT is what I want for my basher.

There are lots of ppl who say the Granite is great once its all upgraded to 4s parts. Arrma should have built it that way if thats true.
Its not just my experience. Other ppl here have had similar experience with the Granite 3s. I think the big tires on the 3s chassis just push it to its limits.
