I would post this in the project x area, but the img code is still off, and I want to ask some picture based questions.
So my idea is to mate a pair of emaxx trucks back to back and use a single pair of rear bulkheads to attach both chassis. I just finished making the dual pinion diff that I am going to use to transfer power to the rear set of wheels. The tranny will be on the front chassis, and I will have the front and rear wheels steerable while the center pair are fixed.
Below are some pics of the dual pinion diff I made. Using new emaxx diff cases, just bought 2 packets of them and cut them in half, then plastic welded them together. Took about 45mins to do start to finish. I plan to run revo spools in all 3 diffs, for maximum traction.
Not the prettiest thing, but I am going to bash this truck, and it will be made out of well used spares I have laying around
