This project started out with a raw kit and dreams that a mild brushless motor system would wake up this dream truck.
Everything about the RS4 MT is sweet, sweet, sweet. The speed and handling of the car is absolutely awesome! I'm actually quite amazed the RS4 MT isn't more common out there. Perhaps it's because most of the sanctioned track races are running 2WD stadium trucks and won't allow the 4WD trucks to compete? The RS4 MT can be adapted to so many terrains. Drop it down for the high-speed street style, or pick it up a notch for some aerial off-road bashing. Either way, there aren't too many trucks out there that you can actually steer under heavy throttle and actually expect it to go there. The RS4 MT does, and does it well.
Below shows the truck with brand new Novak Super Sport brushless motor system which has been run through only 1 battery pack. This setup works much better in the RS4 MT than the Lehner motor / Schulze controller setup from the previous generation of the truck (pictured above).
The Novak system is sensor type, so it's much smoother than any sensorless brushless motor system and even smoother than high-end brushed motors, not to mention how powerful it is.
