That's Sherri from Sherri's hot rockets. Technically it flew on a pair of G80 SU motors but barely and not safely and it REALLY needed alot more motor. Sherri wasn't HPR certified so the pair was the most that could be used. (Ignoring theories about Sherri vs her husband who actually built and flew the rockets, no way to prove it either way)
Mine has a central 54mm and 4x 29mm but it's not even half as good as Steven's
Much thanks! So that looks like at least or about 1:48 scale - depends on all tall Sherri is! Golly will @Steven's bird be something to see! ETA: Yes, of course it's 1:48 - went back to the first post to review...
