Büttner Propeller

Büttner Propeller is a German aircraft and aircraft-component manufacturer based in Obernkirchen, Lower Saxony. The business was founded by Gerald Büttner and is also associated with the name Gerald Büttner - Obernkirchen. Its work combines the development of complete light-aircraft designs with the manufacture of propellers for ultralight and microlight aircraft. The company’s aircraft activities focus on powered-parachute and paramotor aviation. Its paramotor range is marketed under the Büttner Crazy Plane name, while its powered-parachute trike designs are known as the Büttner Crazy Flyer. These aircraft are intended as ready-to-fly designs for European Fédération Aéronautique Internationale microlight categories, including the 120 kg class. The product concept places the company within the recreational and sport-aviation segment rather than the mainstream general-aviation or commercial-aircraft market. Büttner Propeller also manufactures propellers as a distinct product line. Its documented offerings include two-bladed carved wooden propellers and two-, three-, and four-bladed plastic propellers for ultralight aircraft. This combination of airframe, powered-parachute, paramotor, and propeller expertise gives the business a specialized position in light aviation, where propulsion efficiency, low weight, compact packaging, and compatibility with small engines are important considerations. At an earlier stage, the company also produced the Büttner Easy Plane. Public reference material does not establish the model’s production dates or current availability, so it is best treated as a historical product rather than a confirmed current offering. Similarly, detailed information about the company’s workforce, ownership structure, production volumes, financial performance, distribution network, and international sales is not publicly established in the supplied sources. Büttner Propeller is therefore best characterized as a specialist German manufacturer serving the ultralight and powered-parachute aviation community. Its Crazy Plane and Crazy Flyer names identify its complete-aircraft activities, while its carved wooden and molded plastic propellers represent a complementary component business. The company’s public profile remains relatively limited, with its official website and the Wikipedia entry providing the principal readily available information.

Büttner Propeller was established by Gerald Büttner in Obernkirchen, Germany. Publicly available reference material identifies the company as both an aircraft manufacturer and a propeller producer, but does not provide a verified founding year or a detailed chronology of its development. The company’s principal aircraft work has centered on small recreational aircraft using powered parachute and paramotor configurations. The Büttner Crazy Plane name is associated with paramotors, sometimes described in German as Rucksackmotoren, reflecting their backpack-style propulsion arrangement. The company also developed the Büttner Crazy Flyer line of powered-parachute trikes. These products were designed as ready-to-fly aircraft for European microlight aviation and were aligned with Fédération Aéronautique Internationale categories, including the 120 kg class. Alongside complete aircraft, Büttner developed and manufactured propellers for ultralight aircraft. Its documented propeller range includes carved wooden two-bladed designs as well as plastic propellers in two-, three-, and four-bladed configurations. This component activity is central to the company’s identity and explains the use of “Propeller” in its commonly referenced name. The business therefore combines aircraft design and assembly with specialized propulsion components rather than operating solely as a propeller retailer or generic engineering firm. Büttner also produced the Easy Plane at an earlier point in its history. Available reference material confirms the model’s association with the company but does not establish when production began, when it ended, or whether it remains available. No verified public timeline was supplied for model introductions, production changes, ownership events, partnerships, or major corporate decisions. The company’s known market is the European ultralight and sport-aviation sector. Its products are aimed at pilots and operators of light recreational aircraft, powered parachutes, paramotors, and related microlight equipment. Information about exports beyond Europe, production scale, financial results, employees, and current model availability remains limited. On the available evidence, Büttner Propeller is an active or continuing specialist manufacturer, but the precise current operating status and breadth of its commercial activities require further verification.
