5.504b Patch — IL-2 Sturmovik: Battle of Stalingrad Steam update #97040

An air drag calculation error of damaged aerodynamic elements of WWI airplanes has been fixed (it made the airplanes with damaged surfaces fly faster instead of slower); There were some reports that improved AAA gunners skill sometimes resulted in killing players in one shot so this change was toned down (AAA skill is low on Enemy Inferiority career setting as it was before the 5.504 update, low or medium on Parity setting and medium on Enemy Superiority setting). Parts of the both Strutters and Nieuport 11 no longer should disappear at a distance when damaged; Fokker EIII motor canopy has polishing effect, cockpit clock is working; Halberstadt D.II anemometer corrected; Racing multiplayer mission on Yak-9s added to Multiplayer\Cooperative folder (you can create a server with this mission in the game, Multiplayer - Create Server - Cooperative - select the mission); Minor text corrections...
