From the Manufacturer

HPI specializes in the kit-type R/C car or truck, which can come already assembled or in kit form, meaning you build it yourself or with a friend. While the kit R/C cars and trucks cost more at first, they are more durable and faster than toy R/C cars. You can also repair this type of R/C car or truck, which is usually impossible or very difficult to do with toy R/C cars. The cost to repair a car or truck is only a fraction of the cost it would take to send a toy-style kit to its manufacturer (if that is even possible). You can also upgrade an R/C car or truck to make it faster, stronger, more durable, more adjustable or just make it look nicer. All HPI R/C car and truck kits have optional bodies that you can replace whenever you want, meaning while you may have a street car today, you can have a street truck tomorrow, or a sedan, racing coupe, sports car, or nearly any other type of car you desire.
