Both versions have steel shafts, the ss has better ones iirc. There are aftermarket shafts that are better still. It is very harsh platform for a drive shaft, I believe there will be some bulletproof ones avalable in time.
Oh yeah, so sure... those tires are huge and heavy, and the length of the chassis allows for zero wheelie (reduces max loading).
I wonder if you could make the thing lighter than stock with 30 mins runtime, and enough power to shame the gassy's?
