Initial run of the Red Racer backyard roller coaster cart on the little rocket track.

For me, the most difficult task in developing a backyard roller coaster is the body of the cart. Designing a shape, building a mold and making a unique fiberglass body, would probably consume more time and money than the welded steel frame. The trouble with most riding toy bodies is they don't interface very well to the coaster frame, and usually sit high. The Red Racer has a foot-powered car body, and the Little Rocket is made from a 15 gallon water barrel.
