Brief:
Single stage, mid power rocket that uses two body tube diameters. Recovery via parachute
Construction:
Two body tubes (BT-60 and BT-55) 8 fins and 4 body strakes
All part numbers are from Semroc unless otherwise noted:
Finishing:
I papered the fins and used Rustoleum filler primer to take care of body spirals and strakes. The lower body tube connects to the upper tube via two centering rings and a tube coupler. This coupler was used to give more strength. Coat of Rust-O-Leum sandable primer, thorough sanding, re-coat of primer and then shot the first coat of light gray. Two more coats of gray. Photos I have seen of this rocket have no markings so I decided to paint the body light gray and the nose red.
Flight:
My first flight was D12-5. I would not recommend D12-3. You need the longer delay. It also performs well with D15-7 and E15-7.
Recovery:
I used 150lb. Kevlar tied to motor mount. I always use about three times the rocket's length and secure it to the motor mount. I also like to wrap some tape around the cord where it meets the end of the body tube to prevent zippering.
Summary:
PROs: unusual design, good flyer
Other:
CONs: lots of wood needed
