RE: LITTLE TOOT BIPLANE
There's two sources of plans that I'm aware of:
Bob Holman carries the plans for a 38% version by Bob Morse (Mammoth Scale Plans) and Tommy Meyers (son of the Little Toot's designer) carries a 1/4 scale version.
The attched pics are of the model I built from the Bob Morse plans. Wingspan is 87", weight 32 lbs and is powered by a Zenoah GT-80. The cowl and pants are still available from Paul Steiner (contact info is on the plans).
While the Morse plans were easy to build from, the wing incidences shown have way too much positive angle. I rigged mine with the bottom wing at 0, top wing +1 and stab at 0 and it flies great.
The plane is a blast to fly and always gets a lot of attention at the field.
