After some trial and error, I have the general shape, size and technical sides of my RC Formula 1 Project. As it turned out, custom U-joints weren't necessary, and the Buggy motors are quite capable of getting the weight of the car up to speed!
The body is still a very much work in progress.. I want it to have the general shape of a Formula 1 car, maybe from the '90s, while still keeping the weight as low as possible. The current body is just to test weight and the general shape.
The entire underside, except for the current front wing, is flush with the lower arms of the suspension.
