This converts the vehicle from the Titan motor to brushless power. It has completely changed our Traxxas Rustler from a nice mild mannered learning RC into a pavement scorching, wheelie popping, dream machine. When you upgrade this and the batteries to 3 cell 11.1 volt lipo batteries the car becomes a challenge for new users to handle. My son has gone from letting this car rest in the hobby room to playing with it daily regardless of the weather. He prefers this car to our nitro machines and our other lipo vehicles. He hasn't touched the Team Associated RC8.2e since this upgrade. If you have the Titan 12t this will make it a new vehicle.
