i used to be all into r/c cars. had an rc10gt with all the tricks, and an cz-z engine. you know ya can port those little engines for more power? i did it to mine. also shaved the cylinder and head for more compression. i added a small delta computer fan hooked to a small 12v rechargable battery for better cooling and made a duct out of sheet metal for the engine and fan. that thing would do wheelies on the baseball feild i ran it on. i could wheelie across half the diamond before running out of gearing.
