Speaking of Stine's original Flat Cat design, I bought and built one way back in my early years in the hobby and had no problems getting it to boost and glide properly. Before that I
think my only other B/G experience was the Estes Astron Space Plane (loved the kit and build, but the first flight the ejection of the engine ripped the elevon tabs). Then I built one
called the Raven from plans (think it was in the Estes Model Rocket News) and started ordering the B/G and R/G's from CMR (Manta, Orbitron, and Buzzard), which I still have (and
use in competition) today ! I've built an upscaled version of the Buzzard for use with
18 mm engines (I think Gassaway gave me the plans for those back in the 1970's, and, yes
I still use that upscaled Buzzard today) as well as the Nymph slide pod R/G (13 mm). Boost
and rocket gliders are a lot of fun!!
