In Gregs Youtube -canel " Gregs Airplanes " was a new video about the FW 190 A4 ( with MW 50, but I dont believe it gets ever this device in frontline Service ) as a great fighter, the next version, A5, was longer and more heavy. I remember a narrative from Walter Nowotny from early 1943, when he is dogfighting in his FW 190A4 against Airacobras and as I assume, Jaks ( published in Osprey Aircraft of the Aces). Here Im wondering that he could turn with the Sowjet fighters in his FW 190A4. Some times later ( five years )I get a look at a Fotostory about the arrival of Nowotny at Mont Marsan, 24.5.1944, with his FW 190 A4, in my opinion his frontline fighter from 11.43( In the german journal " Luftwaffe im Fokus " Issue 11 ) . For me very intresting is that this fighter was brightly polished, the outer guns and the MG 17 were removed (maybe other things ) and it has weel well doors. In this configuration the FW 190 was apparently light enough to compete in a turning contest with the Airacobras and Jaks. If this was carried out by other pilots of the JG 54 ? I dont know.
