Thank you for viewing. This is a Mini 4WD MS Flex. The Aero Avante clear body has been painted pink, and a teeter-totter system has been added, assembled on a pink MS chassis. Silver springs are used for the suspension. The gear ratio is 4:1, equipped with an Atomic Tune motor, and the front and rear bumpers are AT. It will run if you put in batteries, but final adjustments are needed. Also, the rollers are plastic, so please change them depending on the course. All parts are made by Tamiya. This was made by an amateur, so please refrain from purchasing if you are looking for perfection.
