I saw one on the top of a van in Hartford last week, Pablo. No engine and was wondering. Never dawned on me that it was electric.
Whooly stuff, that must be sick. With front brakes, you could just sit, spin and spraying road sand. lol, be a great racing name. "Sit-N-Spin"
Dang it, now I really wanna build one.
KiwiKidd, I am thinking if you did a DIY with a utility engine, could just use the stock tank or most lawn care engine tanks. The pictures look like motorized bicycle tanks. Those are pretty inexpensive and available all over the net and from most of the sponsors on either side.
Not sure of who sells em down your way. AussieDan or some one else will know.
