I wanted a model rocket that retained the spent engine (I live in a dry area). But I wanted a recovery method that wasn't the usual parachute or streamer recovery.
Here it is: the Flutterby. On ejection, it separates into two parts: the tail, which retains the spent motor and tumbles back, and the nose, which retains one fin and comes back a bit like a maple seed.
It comes in 3 sizes: the Flutterby (for 18mm A/B/C motors), the Flutterby-T (for T-sized 13mm motors), and the Flutterby-D (for 24mm D-sized motors). I do not have a field large enough to test the Flutterby-D yet.
Printed in PETG. PLA is very unlikely to work, as it will be too brittle and heat-sensitive at the same time. Supports are not needed; just print the flat tube section at the bottom for Fore and Aft, and put the long straight section down for Fin (you'll need a brim).
Each comes in 3 parts: Fore, Fin, and Aft. Super-glue the Fore and Fin together to make the nose piece; a convenient hole permit
