The whole idea of the project was to see how close to reality I can make a scale model perform. Spring rates and resonance frequencies don't scale down realistically when you go down to a 1:10 size, so I had to figure something else out. I've seen active suspension systems made before, but to improve handling. I'm doing the exact opposite. The whole system consists of a an accelerometer, connected to an arduino board, which controls 4 servos, each one controlling the ride height at each corner. It didn't start as a drift chassis, but eventually became one, so the front suspension and steering was also re-engineered to allow for a great turning angle.
