I am a part of a high school engineering program that is currently working on a 1:10 scale red cat drift/oval car I believe. We are racing in an oval, road course, and drag. We are fairly new to these cars and would like some advice. We've heard that low light and left is good for the oval, and of course lighter is faster and more efficient but still looking for better options. We're currently running carbon fiber chassis, shock towers, and center stiffner with adjustable shocks and plastic everything else because it's usually 50% lighter than the aluminum upgrade kits. We have also locked our rear diff with jb weld and are only running rear wheel drive so the motor and battery don't have to turn two diffs to maximize efficiency. Advice on any parts, set-ups, or anything will help. We greatly appreciate this and are willing to share any knowledge we have that includes locked diffs, weights, etc. thanks!
