I've got a rather LARGE motor, 1/10th scale electronics ESC, etc.... maybe it'll fit, lol.
I think the best upgrade would be a HUGE motor and electronics. Weight reduction is nice but might hurt you if you've got too much horsepower. Unless you microwave your tires the weight reduction might end up leaving you spinning.
I'd like one to put in a mini-jet engine in
