My lasting(?) impression from reading the "Doodlebug" articles was that the "Doodlebug" design was intended as a de-tuned version of the "Humbug", in reaction to the latter's lack of acceptance by the stunt community.
Oh, let me look it up...
Yeah, he opens the first article, "The Doodlebug design goal was to achieve Bi-Slob/Grandpa's Bipe performance with a profile monoplane and flap-free wing. The strategy was to let the excessive induced drag of a 2.6 to 1 aspect ratio wing hold down the speed during post-stall loops and somersaults...Since the flight envelope wasn't going to be judged officially, the stabilizer as adequate..." He goes on to say that despite 15-degree offset, 75-degree elevator throw, and other gestures in this direction, performance didn't meet his expectations. So he took out the offset, added nose length, doubled the stab area, and arrived at what he termed a "competitive stunt machine." He writes that, after he'd crashed the first version, the Judges were "kind enough to state that the flight characteristics were adequate to compete in the intermediate class." I think he sees it as better than that, but he hasn't written anything that indicates to me that he sees it as a world beater, either in his articles, at VSC, or via e-mails. He just says it's "comfortable" with good line tension, rounds, and corners.
I'm pretty sure though that I did read something or perhaps heard from Bill that this one was NOT intended to challenge in the cornering department. Maybe that was a latter Bare-Cat design. Hmmm...
I thought I could find my VSC Doddlebug picture(s), but I couldn't find them either.
