I have prints for both the Miss Behave and the Baby Miss Behave. There were two iterations for the "large" Miss Behave, a 1945 version which had a built up wing and covered with a thin mahogany skin, about 170 sq in area showed an Atwood Champion for power!! The 1946 version was the same basic model but came with solid balsa wings which came airfoiled. See the site referenced in Dan,s earlier post. My plan is the first version. Both used a flat bottom section, very thin so all I ever saw one do was go round and round. Very popular model with an Ohlsson 60 up front. I was poor, could only manage a Baby version! The later model with a symmetrical section came later, I would guess about '48 or so, a totally different airplane, much larger and a decent stunt airplane.
When I moved to Texas I looked up Johnny Casburn and asked jf he still had any plans of the models and unfortunately he did not, he was doing RC stuff by then,1995.
