IA-41 URUBU (HO-XV C) was a side by side glider, built in 1951 in Argentina. It was the first glider to go across the Cordillera de los Andes, piloted by Heinz Scheidhauer.  Port wing upper damaged fabric was replaced with transparent plastic to show structural details. Part of the story of the Horten flying wings in Argentina is documented in the book 'Las Alas de Peron' (Peron's Wings) by Ricardo Burzaco published in Argentina (1995)  ISBN 987-95666.  (Full picture is:  82kb)

Starboard wing showing small all movable rudder that replaced the original spoilers which were hated by some glider pilots.  The sky-blue leading edge portion corresponds to the wooden torsion box; behind it, all is fabric.  Over the rudder it can be seen an Avro-La Cierva rotor blade.  (Full picture is:  57kb)
