Cutaway Hafner Rotabuggy, Raoul Hafner its designer's proposal to specification 10/42, which called for a rotary wing fuselage designed around the Willys Truck 5cwt 4x4 Model MB. to provide greater forward mobility at lower costs than gliders, of the many projects that saw the light of day, mostly troop-carrying gliders, artillery pieces or light vehicles prevailed, designed to provide rapid movement and use the element of surprise to achieve advances. The Hafner Rotabuggy is an adaptation of an "Autogyro" structure to a Jeep that would allow it to be towed and released in front where it would land in a small area smaller than that needed for a cargo glider, it would use a large two-bladed rotor attached by a triangular tubular structure to a Jeep, behind which a square tubular fuselage would be attached, this was covered with plywood and horizontal surfaces with elevators and two huge fins, the project was presented and soon problems of yaw were observed so the surface of the fins was increased, this concept, project and evaluated prototypes do not cease to be striking, I have very little information about its functionality, the conclusions and decisions that were taken after their evaluations, speculative schematic section actually a work of "Aeronautical Archaeology" on one of the many aeronautical curiosities created during the Second World War. Something important to highlight is that although it seems very simple in reality they had many complications with the vibrations of the rotor shaft and the control shaft. In the end, the solution of the Horsa II and Hamilcar gliders prevailed. Motocar
