EMaxx chassis

[Buzzsaw46]

The mugen diffs have a 5mm output shaft rather than the 6mm of typical 1/8 scale diffs. I found some Ofna 5mm diff shafts but the cross pin hole was 2mm rather than 2.23mm. So I tried 133mm HB D8t dog bones and the ball end is about .4mm too large for the traxxas axle. I should have quit at that point but I tried Losi 8T 2.0 bones and same as the HB too large on the ball end.

The solution was Hyper 7 diffs with HB ring and pinion and the diff shafts in the hybrid kit, along with the stock traxxas drive cups I have the rear end all buttoned up.

I was just hoping to be able to run 8s packs and still keep speeds in check with the 1717. As it is with 4.3:1 diffs the slowest I could gear for on 8s is about 60mph.
