Bi plane, Bucker Bu-131 Jungmann

The Bücker Bü 131 Jungmann was a German two-seat training aircraft produced by Bücker Flugzeugbau GmbH (Bücker Aircraft Company) in the 1930s and 1940s. It was designed to be a primary trainer for the German Luftwaffe (Air Force) and was widely used for this purpose during World War II.

The Jungmann was a conventional, single-engine biplane with a fabric-covered steel frame. It had a simple and robust design, making it easy to fly and maintain. It was powered by a single inline piston engine, which gave it a top speed of around 160 km/h (100 mph).

The Jungmann was used to train pilots in the basics of flying, including takeoff, landing, and basic aerobatic maneuvers. It was also used for advanced training, such as formation flying and gunnery.

After the war, many Jungmanns were sold to civilian pilots and flying clubs, where they were used for sport flying and aerobatic competitions. The Jungmann remains popular with vintage aircraft enthusiasts and is still flown in airshows and fly-ins around the world.

In summary, the Bücker Bü 131 Jungmann was a versatile and reliable training aircraft that played a vital role in the training of German pilots during World War II. It has continued to be popular with pilots and aircraft enthusiasts in the years since the war due to its easy handling and classic biplane design.

I printed mine in PETG at 255C on an ender 3 pro,
using White for the body, transparent on the wind shields and black for the tires.

The piece is broken up into parts which push fit together and
The joints are all round number circles, meaning the holes can be cleaned out with a standard drill bits.

I recommend printing the wings with the leading edge pointing at the build plate as they have a slight curve which will require supports.
