 Designed by Fairchild (Canada) in the hope of attracting orders from the Royal Canadian Air Force and Canadian Airways,the 45-80 was an ambitious project, being the largest design yet attempted.The Sekani was a large sesquiplane of conventional configuration, with the sets of wings joined to the top and bottom of the fuselage and braced by N-struts.The lower set of wings were little more than stubs; their bracing to the upper wings passed through the engine nacelles (mounted on the upper wings), and they carried the pontoon undercarriage beneath them.
