The launch is called Balls--if you have the Cojones to try it, you can go to it. I believe the FAA approves a 100,000 ft (AGL) altitude permit for this. Do not know if they asked for a waiver for more, but guess they did, as software simulations are available, though that extreme motor might need some tweaking for the software to work. Dan & I watched a rocket flown on the Salt Flats (though the launch "LDRS" had gained access to the Air Force portion of the flats included in their bombing range, which gave an permit for flights to 50,000 ft. That rocket, I think, had a diameter of 8" and was about 18 ft long. It was powered by 3 "M" sized motors. I can't remember the altitude, but think it did not get above 10,000 ft due to its weight & size. Patrick mentions the Estes rockets, powered by A through D black powder engines. Each engine doubles in power as you go up. I believe a standard "Q" motor was thought to be about the size of the motor in the Air Force's Sparrowhawk air-to-air missile. I am thinking this motor had to be a "souped up" version. Look at the web site for the Utah Rocket Club for further info. http://www.uroc.org/ Larry Holmes UROC member (Level 1) On 10/10/2011 5:34 AM, Patrick Wiggins wrote:
And to think I used to think my Estes model rockets were pretty neat.
Great video:
