Mini 4WD - Mini 4WD Assembly

Mini 4WD Assembly

Mini 4WD can be purchased in hobby stores or online. Some of the mini 4WD manufacturers do not include an electric motor required for the car to function. The car can be powered by AA batteries, including rechargeable batteries. Its body frame has a front bumper extending sideways to hold the rollers for the tracks. An optional plastic bumper for the rollers comes for the rear of the body; some chassis designs have roller placements mid-ship. For 4WD (four-wheel drive), traditional models have a propeller rod driving both the front and rear axles; as for the Mini 4WD PRO series, the motor located in the center of the chassis powers both the front and back wheels. The assembly package usually comes with grease for the gears. Although the chassis concepts for the Mini 4WDs remain the same for the models of the series, the body which can be made out of hard plastic or soft, transparent polyvinyl carbonate (PVC) for special or limited editions, which attaches with a catch-type lock at the back of the car, distinguishes one model from another; additionally, the wings on the plastic bodies allow for improved down force and stability.
