I've thought about making parachutes out of the silk hankerchiefs my wife tie-dyed. After the Wavy Gravy paint thread it really got me thinking about a rocket for her.
This design is based on a BT-60 with the rounded nosecone and a Toucan Tie Dye chute from rocketchutes.com. I still haven't decided on 3 or 4 fins so I simulated them both. I didn't have the proper specs for the NC so I just BSed it.
I've never done fins that insert into slots in the BT. Will that make the joint stronger? These will need all the help they can get.
