On the 24th of January 1926 with his friend Walter Kreiser was given a patent for an autogyro . In 1927 Rieseler and Kreiser build their first autogyro. Financed by a Hamburg banker, the autogyro which was conventional in design, but featured a four-leaf rotor. Unlike Ciervas design, Rieseler's autogyro had blades that could be adjusted in flight. The first flight showed a strong oscillation that could not be eliminated. At this setback the banker withdrew any further funding.
