To see the Flying Stovepipe plans: CLICK HERE This was Estes Plan #56 from 1968.
This rocket is basically a old Astron Scout in the center except the fins are shaped with a one sided airfoil to induce spin during boost. At ejection there is (hopefully) enough still enough rotation to give you a gliding ring recovery.
I always wanted to try this one but was concerned that the flight results might not be worth the effort. I remember reading somewhere that the original designer, Larry Deran was still tweaking the design.
