I have always been able to furball in an IL2 becasue of how I setup the views to work with TR. I detest doing it since it's not designed for that. Taking one out into a fighter infested area is willfully ignoring reality. F3 is asking Hitech to give you a gamey solution to furballing with a single engined plane that was not designed for air combat. Half the time when the IL2 had F3 mode, when the player pushed the nose down in that famous Ghi move, the collision model killed you not an over shoot shot by Gui. Nice gamey way to win especially if you know how it worked.
The IL10 was to address the lack of maneuverability short coming with a higher speed of 315mph at sea level and better maneuverability. Wish for the IL10, about 120 made it into combat in 1945. The high velocity AP rounds for the VYa-23 23mm canons could penetrate 25mm steel plate at 400m. Only the TigerII engine hatch would be impervious which it already is to the IL2 37mm.
