Rusavia Polikarpov U-2
During the first flights in 2004, the Shvetsov M-11FR radial was damaged and needed to be overhauled. Albatros Aviation Services carried out the recent engine rebuild, using many hard-to-find original parts.
Slovak Republic-based Polikarpov U-2 replica 'White 7' (OM-LML) took to the air again after the engine overhaul on October 11, 2007. This machine was built by Rusavia in Moscow and was gifted to the Museum of Aviation collection at Kosice by Russia in August 2004.
