Hi, Gerald Schamp here, and I do have the Proto profile Corsair that Pat Johnston built. It flies really well, especially for a plane this size without flaps. I changed power plants from the orginal LA .46 to a Saito .40 four stroke with Pat's carb mods. Engine just loafs along with this plane. I have not had the opportunity to try it in the wind, as Pat has cautioned about that. Although at our Salem, Oregon flying site, one can get almost any kind of air at any time. Having said this, I have not had any problems with line tension or anything. What I have learned with this plane, if it does something funny on the end of the lines let it fly and don't try to over compensate, it will motor on through. Landings are really tough, when the engine dies, just let the plane land, its a really nice two wheel landing and roll out, just like the real thing. Now if I could just figure out how to build one of Al Rabe's torsion landing gear for it, that would be really cool.
