this ended up being a nightmare project, the body was 3d printed for 20 scale, how ever the 3d printer did not understand the difference between a toy car body and a rc car body so it is vary heave duty construction and weighs in at just over 1 pound.
so the 20 scale body got mounted on a 18 scale truggy chassis with a brush-less engine.
none of that was easy, it has front magnetic mounts and the back sits in the racing wing held by a single spike, then their were the open sides to deal with.
I decided it needed to be fully illuminated so the wiring took a bit of time.
