Nice design!This is the furthest flying glider I have ever made. It is my own design. It is hollow, with no internal weights. It, standing 30 feet into the air got over a 300' foot glider with this plane, it banked right, into the wind, climbed, and ended at the end of the train station I lived near, at the time. It did not crash, it landed perfectly. The nose was a lifting surface, that translated into the main wing. The large aileron was placed to get the center of gravity where it should be, with the angle of incidence also set by the tilt of the rudder, holding the elevator. It had flaps and ailerons, but I found If I built them square, just the major adjustments when made, and a proper airfoil, the glider is perfectly flat on the bottom, gave for almost dart like flights inside.
