BUCKERJUNGMANNBU131LIONHEARTBIPLANE

4.5/5 (268)


Nicknamed the Stradivarius of antique light aircraft of the 1930s, the Bucker Bü-131 came to be in 1934 with its first flight occurring on April 27th of that year. The Jungmann (pronounced Young man) was designed by Karl Bücker. The first model of Jungmann, the Bü-131A, went into production and rapidly became an extremely popular aircraft of that time, with most of Europe wanting these to train their pilots. Not long after the release of the 80HP Bü-131A did the Bücker Flugzuegbau firm released their second Edition version of the bi-plane, the Bü-131B model. The 131B had the updated new Hirth A-2 sporting 105 HP. This new version was then licensed out to many European countries including Spain, Japan, Romania, Hungary, Yugoslavia, and Switzerland. (Many years later, other countries would go into limited production runs of the popular design).

This version of the Bücker Bü-131B by Lionheart Creations is the Swiss model which 99 units were produced in Switzerland. This particular model shows you a modernized version of one that would be typically owned and modified to todays standards, which includes fitting of radios (COM1 and Transponder) and NAV lights for night flying. I have also hidden a bare-bones autopilot in the instrument panel that has basic AP features. A free-to-download owners manual of this plane is available to show you in more detail how everything works.

The Bü 131 Jungmann is a two-seat, single engine biplane developed and produced by German aircraft manufacturer Bücker Flugzeugbau. The Jungmann (“Young man” in German) took its first flight on April 27, 1934 and was introduced in 1935. The aircraft was used as a basic military trainer, primarily for the Luftwaffe, but also for the air forces of other counties through the decades, including those of Czechoslovakia, Greece, Japan, and the Netherlands. Roughly 5,000 Jungmann aircraft were built, with a production run that lasted from 1935 to 1945.

The Bü 131 Jungmann measures 21 feet, 9 inches in length, has a wingspan of 24 feet, 3 inches, and stands 7 feet, 5 inches in height. It features a tandem open cockpit, a fixed traditional undercarriage, and a standard empennage. The fuselage is constructed using steel tube, wood, and fabric, and the wings and tail section are built of wood and fabric.

The Bü 131 is powered by a single 4-cylinder Hirth HM 504 inverted in-line engine that produces up to 100 horsepower and turns a 2-blade, fixed-pitch propeller. The Jungmann cruises at 110 miles per hour, has a top speed of 114 mph, and lands at 51. It has a range of 400 miles, a service ceiling of 14,100 feet above sea level, and climbs at 500 feet per minute.

The Bücker Bü 131 Jungmann is an aircraft with an elegant, classic design that treats pilots to forgiving performance. From within the open cockpit, aviators can fly easy lines through the sky, practice touch-and-gos, or push their abilities all the way to detailed choreographies of complex aerobatics.
