She saw a few of my store bought and scratch built machines and decided to build one. She did find a 29 mm id cardboard tube. It was something that that I had found. She carved a nosecone from white foam and coated it with flox and white glue. The motor mount was something left over after losing a rocket. It had a 24 mm ID and a 29 mm OD. She glued it in and put on 4 simple fins left over from an estes Super Neon XL
It's weight without motor was 90 grains. We used an old D motor casing as a C6-5 motor holder for the first flight. Looking on a simulator it was marginal for launching but worked fine.
The thrustcurve site said it would go over 500 feet. We recovered it 50 yards away.
Yesterday we used a d12-5 and got a more aggressive launch, Was very straight and out of sight in a second. Thrustcurve.org said that it would go 1148 feet up with a 6 second delay fuse, our motor had a 5 sec delay. It has a 48x1 inch rip stop nylon streamer. Never found it It rained last night and again today. We went back in the woods and found it about 700 feet away from the launch.
It was a little damp and 3 of 4 fins were off but went back together well.
