Even IL2 is getting built in support for separate controls on multi-engine planes and on top of that, the addition of separate control profiles, thanks to TD.
For example, you will be able to have 2-3 different control settings. Before flying a P-38 you will be able to choose your twin engined profile from within the game so that you can control the throttles separately with your Logitech G940. When swapping for a P51 you will be doing the same for a single-engined profile, so that one of the G940 levers acts as a throttle and the other as prop pitch, and so on. This will be coming in one of the Team Daidalos patches.
So, if IL2 is getting such options, i'm sure SoW will be getting them as well
What would definitely rock would be the ability to set aircraft-specific control profiles.
