The Estes Mongoose is the perfect first time building and flying experience for a fairly new rocketeer who wants to try their hand at launching a two stage model rocket and explore low hanging clouds! A two stage rocket has two sections of the rocket with the engines stacked or staged one on top of the other. The lower stage contains a booster engine that kicks the rocket off the launch pad and the second stage has a standard engine inserted into it for extreme flight altitude. Recovery is usually by parachute or streamer. The action is always hot when flying a staged model rocket!
