There was one 1/2A design I built a number of. Not a kit, but still one of the best 1/2A flyers I ever had. I was reminded of it last week from seeing a nicely done build and fly video on one of the MA websites from a young Brasillian. The plane was the Li'l PT. Forget who designed it, but it was a full size plan in the March 1960 MAN. Remember when they were actually a full service model airplane magazine? Very smooth flyer, compared to many others I had. Think it would have done very well with a Golden Bee or Black Widow and 42' .008 steel lines. A piece of the sig airfoiled 3" balsa for glider wings would save a bit of work, since instead of a flat plank wing like many, the plans called for sanding the 1/8" into an airfoil shape.
I used to build and fly them, with the impatience of youth, so rapidly neither the glue nor the dope was fully dry. Did my first loops and wingovers with them. Tried inverted flight and outside loops, but for some reason, the engine would quit, and the tank would be dry when the plane came down, with the Babe Bees. The plans (I have some of the original mag, and I've scanned the plans to a computer file) show both tank moung and beam mount. Hmmm!. Beam Mount. Norvel or AME .061. Or Tee Dee .049. Another future project?
