Bucker Aircraft

Bucker Jungmann (Bu 131) and Jungmeister (Bu 133) biplanes are among the most prized vintage aerobatic aircraft in the world. The Jungmeister dominated aerobatic competition from the mid-1930s through the 1940s and is considered the absolute master of the snap roll. Only about 200 Jungmanns survived to the 21st century, making them scarce and commanding premium prices. Their handling is described as sweet, incredibly well harmonised, and a delight to fly.

The Jungmann offers light, responsive controls that remain well-balanced throughout its 120-knot speed range. Pilots consistently praise its harmonized handling — often rated above some modern aerobatic types. The Jungmeister single-seater takes this further with a high power-to-weight ratio and ailerons on both upper and lower wings for razor-sharp roll response. Both types reward precise stick-and-rudder flying.

Most surviving Buckers have been re-engined — many with Lycoming or Continental replacements for the original Hirth or Siemens engines. Verify engine type, airframe history, and structural integrity of the wooden components. Some are Spanish-built CASA 1.131 Jungmanns rather than original German Buckers — these are more common and usually less expensive. A vintage biplane specialist should perform any pre-purchase inspection.
