80% ultra light replica of the Sopwith Pub. It has duralumin tubing and is powered by a 1.8 liter Volkswagen engine.

Construction began on this all-wood Zlín XII replica in early 2018 and the finished aircraft completed its first flight on Sunday, August 16, 2020. The project team used documentation about the original aircraft from the archives of the Military History Institute that is responsible for governance of the Letecké Muzeum Kbely. The plane carries the number '149' on the nose, however, the real Zlín XII of this serial number was produced in 1937 as the 49th plane of the type. It flew as OK-IPS with the Aeroclub of the Czechoslovak Republic and later with the Slovak Air Corps as OK-NAU.

In pre-WWII Czechoslovakia, the Tatra company obtained a license in 1935 to produce Bücker Bü 131 Jungmann aircraft, which were then given the designation Tatra T-131. After the end of the war, it was decided to continue production and this example was built in 2003 by Historical Aircraft Services Karasiewicz in Poland. The aircraft is painted blue as the original owner was related to the WWI fighter ace Georg von Hantelmann, whose blue Fokker D.VII is pictured on the tail.

This Po-2 was manufactured in the Soviet Union in 1937 and is a WWII veteran, serving with the Red Army until 1945, when it was donated to Yugoslavia along with about 80 other machines. It flew with the Yugoslav Army and then in local aeroclub service as YU-CWJ and then YU-CMY. Between the years 2004-2005 the plane was completely restored and an original Švecov M-11FR engine re-installed, after which the plane was re-registered S5-MAY. In May 2014 it was acquired by this museum specialising in early aviation and flown over the Slovenian and Austrian Alps to Mladá Boleslav for display.
