Is this bigger than a scud?
The name of this rocket is "Down Right Ignorant". It was launched in 1993 at LDRS XI.
The rocket was powered by 1 "O" motor, 5 "L" motors, and 8 "K" motors. The Estes kits sold in stores are rated as A, B, C, and D motors, each consecutive letter having twice the total power output as the previous. This makes an "O" motor 16,000 times more powerful than an Estes A motor.
The rocket at a wieght of 800lbs reached an altitude of 3,500 feet and was sucessfully recovered. Even though it doesn't seem like it, 3,500 feet isn't all that high. Smaller rockets powered by a single O motor have gone beyond 35,000 feet.
All that being said, these rockets are nothing like Scud missiles in that they have nowhere near the range of a scud missile. In order ot equal the range of a scud, a very large and very expensive motor would have to be custom made. Something like that is well beyond the scope and capabilities of the materials available to hobby rocketeers.
