Another rocket from my FSI cloning project. This was actually the first one I built, back in December 2006 - January 2007. It was the rocket that kicked off the project. I love using 1/16" birch plywood for fins. They are hard to cut but easy to finish and wow are they ever durable. The upper section in this rocket is not for payloads; it actually houses the recovery system. Just as in the original, I drilled a passage through the solid wood transition (originally hardwood; mine is balsa) so that the ejection charge gases could go from the motor in the lower section into the upper section and push out* the parachute and shock cord. The transition and upper section are bonded to the lower section and do not detach. The separation point is the nose cone.
This rocket is extremely stable and flies like an arrow when it is launched. In it's first flight it went nearly out of sight on a C11-5.
An article on my Nova is here.
(* Yes, that's right, I said push out. If you saw the rocket first hand, you would immediately understand the mechanism. )
