The E-Savage is the newest way to experience the fun and excitement of our "Proven Tough" Savage Monster Trucks From entry level beginners to frequent racers, this is an excellent choice for all off-road enthusiasts. The all new chassis design was inspired by the time tested durability of our Savage line. Additionally, the balanced symmetrical layout, AWD drivetrain and awesome power of twin 14.4V GT550 electric motors give this Savage excellent performance on or off road. Twin Motors & Twin Batteries Two high-power 550-size motors developed exclusively for E-Savage are included. Each motor has a cooling fan inside so the motors run cool and generate high power. Two 7.2V straight packs are included that can be completely charged by the special high-speed charger in about 50 minutes. The fully charged batteries last about 10 minutes in continuous use (duration varies with driving conditions). All new speed control The E-Savage comes with an exclusively designed speed control to control high power from twin motors and twin batteries. The FASF (Fully Automatic Setup Funciton) automatically sets up the default program and the fail-safe device in the speed control and automatically protects the circuit in case of overload for driving at full throttle with no problems. Complete set of ball bearings Twenty two ball bearings are used in the drive train to help transmit the power of twin motors and twin batteries to the tires efficiently. Low-profile tires Big 5.4 inch diameter tires easily climb over fist-sized rocks. The block pattern of the tread ensures stable grip on straightaways and corners. The low-profile design helps make the truck look stylish. Tires: 5.4 inches in diameter / 2.8 inches wide Wheels: 3.5 inches in diameter / 2.2 inches wide (Compatible with SAVAGE) Symmetrical AWD layout The E-Savage has a unique symmetrical powertrain layout with twin motors located around the center and twin batteries on the left and right sides of the chassis. This layout creates excellent chassis balance to contribute to great driveability on rough terrain and stability in high-speed driving. The E-Savage RTR contains everything you need to run at the track. A completed chassis, radio set and printed and trimmed body are all included in the E-Savage RTR kit. It also comes with drive batteries and high performance quick charger capable of charging two battery packs simultaneously. Required Parts 8 AA size batteries for the transmitter
