 Double Ringer - A Scratch Build

This rocket is based on the old Estes Double Ringer design.

It's an upscale to a C-204 tube and uses (2) 4" nominal diameter tube fins. At ejection the (2) tube fins separate and glide down while the main rocket parachutes down on a 18" parachute.

Rear Eject spool with a 29mm motor.
