I've been noodling at this project for a while, and finally have enough to start up a build thread.
This is an oddroc that has it all: Spinning, 3-D printing, burn strings, Rube Goldberg mechanics, base drag, sketchy recovery, options for gross overpowering, and a few fragile parts thrown in for good measure. It'll be a party.
The basic concept is here. On ascent, it's more or less a shuttlecock. Once the D12-0 motor in the middle's ejection charge torches the burn string(s), the booms pop up and it becomes a flat windmill.
Totally normal, Lord RSO, I promise!
Power is up to 3 24mm motors. I need a D12-0 in the middle for the burn strings, but the outboards may well be composites. I'm thinking a pair of CTI F79 SS as the top end motors. Total altitude, maybe a hundred feet. Follow on to a few more posts about the design...
