Tripoli MN had a launch on Saturday and I flew 2 rockets. My successful flight of the day was the second flight of Cindy Loo Hoo, a 54mm minimum diameter rocket 6 feet long and powered by a Kosdon K750W motor. The flight went great! It leapt off the pad and shot straight up in the sky with a white trail of smoke. After the smoke charge ran out it was out of site to all of us on the ground. We followed it with the Yagi antenna on the rocket hunter and could tell it was still alive. We looked and looked and could not see it in the sky. Soon we assumed it was on the ground. Then a spectator came up and said they saw it land and pointed in the same direction we had gotten from the rocket hunter. Myles and I drove over there and I looked around, rocket hunter in hand and finally found it after a half hour or so.
It went 11,511 feet above ground level and reached about 1200mph. It landed just less than a mile away. It traveled about 20-30 mph horizontally, which is about right because the wind was blowing pretty good.
The plot shows the altitude from the altimeter. The main chute came out at about 600 feet. It landed at 30 ft/s (20mph). Perfect flight! Too bad I didn’t see very much of it!
