This video is part of my site sunny-boxwing.de/prehisto.htm which shows the polars of an old aircraftdesign found in southameria in various examples. The wings were investigated with a vortex-lattice program and the transferred in the simulation software x-plane, which can show the flight dynamics very near to reality. The ancient wings perform well in the glider mode. An other video shows the craft as an ultralight with sleaker fuselage and 40 hp.
