I have about 70 or 80 Scientific plans, and the Cadet is there, somethere, I think. $5 shipped if I have it, or we can swap for something, since price is trivial.
I am flying a Giant (Fox 35) Stuntmaster right now, but don't have the plans. This is the one that sat in a pole barn for decades before I restored kit, and hornets had made nests in the wing. I thought I had cleaned them all out before covering, but after a few flights, it would sound like sand moving around inside (the nests would quickly pulverise once in the air). So I would shake and shake the plane, OB wing down, slit the silkspan, and remove the stuff to the outside of the airframe, kind of like shaking salt on your McDonald's fries. Thinking this solved the problem, would fly again, and once again, more hidden nests would turn to salt. And so on, shake, etc, about three more times.
The G. Stuntmaster is interesting, in that Scientific had very few larger sized CL models (Giant Kingpin is another). The aspect ratio is small, and a one wheel LG (a la Flite Streak) is intended by the design, but I put a conventional two wheel on mine.
Both the G. Stuntmaster and Kingpin are hard finds as kits, so grab 'em if the opportunity arises.
