DynaStar Rip-Roar

Rip The Sky Apart With A Roaring Two-Stage Rocket! The Rip-Roar kit from DynaStar Mid-Power Model Rockets is intended to get you a roaring applause whenever you fly it. When the first stage ignites, it rips its way off the pad and into the sky. But the fun doesn't stop there. Next, the booster stage drops off, and the second stage takes over and continues the roar to astonishing heights. Finally, when the rocket seems to be just a tiny speck in the sky, the colorful parachute pops out, and the model gently floats back to the ground. Fly it again and again and get the same great applause. The best feature is that while this is a big model rocket, it is lightweight and can use the inexpensive "D" size rocket motors. So you can get big-time fun with little rocket prices. Pop-N'-Go Staging This rocket was designed to be simple, simple, simple. It uses the simplest kind of staging, called direct staging (sometimes called Pop-N'-Go), where the booster stage ignites the upper stage. Another example of a simple feature is that the booster stage uses tumble recovery. That means it doesn't need a parachute or streamer to make it fall slowly to the ground. It tumbles end-over-end, and by doing so, it slows itself down. It lands very gently and safely. It is one of the biggest rockets ever made that utilizes the tumble recovery technique for the booster section. Because of these simplifying features, this rocket is quite inexpensive compared to other big two stage rockets. You'll get the thrill of flying a big rocket with the loud roar of the motor and the billowing smoke. Yet you'll save money that you can use on other rockets. Recommended 24mm diameter rocket engine: Estes C11-5, D12-5, D12-7, E9-6 and D12-0 for booster stage.
