Designed by Ing. Albert Markwalder and built by Enst Bärfuss circa 1968, the Markwalder Marabu is an all-wood three seater featuring plywood skin over the entire structure. The cantilever wing houses four aluminium/polyester fuel tanks. Wing root fillets and wingtips are of moulded fibreglass the vortex-control tips modelled after those on the Cessna 210. Airfoil at the wing root is an NACA 23012, tapering to NACA 23006 at the tips. Flaps lower to 60 degrees.
The retractable landing gear is manually operated, swings aft into ‘blisters’ under the wings, leaving the tires partially exposed to reduce damage in the event of a gear up landing.
