Custom Model Rocket (2) Body Tube & (3) Fin Can types

I designed these rockets for my son's Boy Scout patrol. They wanted to have a rocket launch and I thought it would be unique to design and make some that you couldn't buy. I have to date flown them on Estes A8-3 and B6-4 18mm motors. I used a 12in parachute for one flight and then tried a 1in x 30in streamer. Both worked perfectly.
