i designed this car to use stock scx24 rear end, front spindles, driveshaft, shocks and electronics. I printed the body in Polycarbonate carbon fiber and i printed the tires in TPU. It use various lengths M1.4 cap screws. The motor is direct drive by driveshaft to the worm gear rearend to eliminate the transmission gear reduction allowing for more speed. This little thing is a blast and it uses all those stock parts that us would usually swap out for better stuff if you are into Rock crawler trucks.
