EXCELSIOR ROCKETRY is proud to announce the release of two new Retro Bash GOONY designs:
The APOGOON
and the
IRON WOMBAT.
The APOGOON is a two stage, gap staged, rear vented design made from 2 Baby Bertha kits!!
As seen at NARAM 46, The Apogoon proves that you can build anything out of a Baby Bertha... or in this case, 2 Baby Berthas!! The APOGOON is a vented gap staged design that follows classic lines. In addition to two Baby Bertha kits, 3/32" balsa sheet, a NB-60 noseblock, and a section of clear plastic tubing is required. (available at your local hardware store in the guise of a flourescent tube cover).
At NARAM 46, a pair of Apogoons were launched one after the other on B6-0, B6-4 motors. Both boosters tumbled to land within 10 feet of the launch pad, and both sustainers landed within 100 feet of the launch pad, 10 feet from one another!!
This rear vented, gap staged design has had 100% success in upper stage ignition. The booster actually flutters down, as a booster should, and the upper stage is easily recoverable, even in a medium sized school launch field. Due to the added skills required for a staged design, we place this model at Skill Level 3.
Plans, patterns and decals: $6.00
