Whichever brand you get, they make a nice stocking stuffer...hahahhaha.
There is a guy at the Air Races who has one with a 2 stroke engine with a tuned pipe. He can mix up a batch in 2 seconds flat.
Only bad thing is the 2 stroke exhaust smells of oil. Make sure you get a 4 stroker version.
I raced karts and motocross. 2-stroke exhaust makes me horny!
