The rocket also got a baffle made from four disks of balsa with an edge clipped by about 1/4 the diameter; these were arranged in a zig-zag layout, with three 1/8" dowels drilled through them and the entire baffle assembly glued together with CA before being installed into the airframe and glued in place with more CA. The kit Kevlar shock cord was tied to one of the dowels in the baffle, and the kit elastic cord also used.
The mouth of the airframe was reinforced with a short section of Estes BT-60, which is a slide fit over the Quest T-40 tube. This same tube was slipped over the nose cone shoulder section, and used as a standoff to support a CMR vacuformed egg capsule. The capsule was faired in with wood filler, hardened with CA, and the diameter step at the rear edge of the BT-60 reinforcement was similarly faired in with filler. Then the entire rocket was given my usual (heavy) finish of half a dozen coats of primer and two or three of, in this case, gloss white. Decals depicting my NAR number (this was, after all, intended as a contest bird), US Air Force, and a whimsical cockpit window and hatch decals for the egg capsule, and Betty-X was ready to fly -- and fly she did.
Originally, I installed dual 18" plastic parachutes, but I found duration
wasn't enough to be competitive, so I changed to dual 24" nylon parachutes
-- these barely fit in the body (thank heaven the baffle eliminated the
need for wadding!), and I had a few deployment problems in early tests,
but in the end, these were what I flew in the contest -- with durations
of close to a minute, I wasn't even close to the NAR record times recorded,
but in all tests and the contest, Betty-X has never claimed the life of
a single egg... B)
