Mine weighs just over 6.5 oz but has plywood fins filleted with epoxy and an "E" length 24mm mount. Entire rocket was built with epoxy and was finished with 12 coats of Aero Gloss Royal Purple Dope. The plastic nose was painted with some sort of Testors Model Master Peuke Green enamel.
I chose those colors deliberately to clash.

Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !
