Nope. If I replace any of the aircraft.lua files in the CoreMods folder in stable 2.5.6 by a modded one, DCS doesn't read it (=> in the mission editor a A10 will be shown instead of the modded aircraft). The aircraft.lua file that came with 2.5.6 is encrypted or compiled someway. Or does it only work with any modding program like OvGME?

Is there a way to use aircraft.lua mods in the stable version again?

Hello, I did a test run with the Bf 109 after upgrade to version 2.5.6. I tested max. IAS at different altitudes at WEP and compared it to historical data. I climbed at about 1000m above target altitude, set the trottle to WEP (1,8ata), dived down to target altitude and let the speed go down on level height until it didn't decrease anymore. results: 590 km/h at sea level - which pretty much refers to historical data 490 km/h at 7050m - which should be at 713km/h according to historical data The attached diagram shows max. speed measurements that were done at "Obb Forschungsanstalt Obermergen" at 11.12.1944. The measurements show data for a new propeller type 9-12199 and for the serial propeller 9-12159 on Bf 109 K4 with engine DB605/ASB at WEP 1,8ata with MW50 injection (which is exactly the configuration in DCS) => the thin solid line "Serienschrb. 9-12159 für K4 mit Sondernotleistung". This seems to be an ingame bug for me. Greats from Germany B@ron
