42.5" Inspirer Biplane
After many years of pondering how the old 22" free flight Inspirer Biplane might do as a 4 ch. R/C model the question has finally been answered; and the answer is, it did GREAT! At the moment, the model is all tested and trimmed, and is flying beautifully.
As the latest addition to the Fantasy Scale Short Kit line, like the J-Kota Biplane, the Inspirer was done as if it were a Home Built full scale airplane. The model utilizes the cowl and dummy Continental engine from the 1:8 Scale Piper L-4 Grasshopper to give it a very classy early Biplane look. As it's set up, the model will do nice loops, rolls, and stall turns as one would expect from a "100 horse single seat biplane with a 28' wingspan". But at the same time, the model is docile, gentle, and very stable for those days you just want to tool around the airport, or shoot a few tough and go's.
The Inspirer is designed to be easy to build in that the wings are not removable, though with it's compact size, is not difficult to transport, even in small vehicles. But don't let the compact size fool you, the Inspirer doesn't fly like a "small model".
The Short Kit will contain 2 highly detailed plans sheets, 7 laser cut balsa and 2 ply sheets and a vac-formed cowl with the dummy Continental engine and wheel pants.

A Second Inspirer Comes to Life
My good friend George Laskar recently finished his Inspirer Biplane from the Short Kit, but he did things a little different. George "back dated" his model from a modern homebuilt to something one might see gracing the skies in the late 30's or early 40's by eliminating the stock Cub style cowl and going with a radial engine. The same power system was used in the second model as in the first, and the flying weight is nearly the same as the original, so there's no perceptible difference in performance -- even with the slightly larger rudder. In all, the simple change from a "flat" to the "round" engine really made for a classy looking model, and nothing but good things came of it.
For those of you who would like to convert your Inspirer to the Radial Engine version, you can look in at Park Flyer Plastics http://parkflyerplastics.com/ for several choices in vac-formed engines.
