Wired for Speed Get ready to race! This handy set combines the popular Aero Avante Mini 4WD car kit with race spec option parts and basic tools. Fitting the option parts in the set turns the Aero Avante into a swift racer suited to tracks with long straight sections and fewer corners. Included are a Rev-Tuned 2 motor, super hard tires (black), brake set, side mass damper set and FRP plates for the front and rear of your car. With relatively few spacers and screws, assembly is kept simple. The Aero Avante body is molded in blue and paired with the aerodynamically efficient AR chassis in black. AR Chassis The AR chassis is designed to offer its driver durability, customizability and ease of maintenance, all of which are key ingredients for a successful Mini 4WD racer. Its aerodynamic form smoothly allows air to pass through the chassis interior as the machine runs, performing the vital function of cooling the batteries and motor and extending their effectiveness. Air intakes on the chassis and body are integrated for optimal performance. Low-friction plastic bearings ensure that any loss of power from the engine to the wheels is minimal in nature. Under panel and diffuser can be removed from the model without taking off the body. Features a 3.5:1 gear ratio.
