hey man
thats quite impresive. i was thinking of getting a tr-15 to play with around my house. any idea how much power the stock engine has gx15r (i belive) could it pull wheelstands if not can your hotted up one pull wheelstands. and can you get a 2 speed for these car's.
btw that is a really cool project
p.s as you can tell im new to rc nitro cars
