I haven't had time to play DCS recently, but I believe the issue is a lack of contrast between units and the terrain. Someone feel free to correct me/expand on this :P
If I remember correctly Polychop have expressed the desire to release variants, but don't currently have the license to do so. I hope that's something we'll see in the future!
I don't quite understand what these alternate key binding slots this mod provides are for. Could someone explain? I'd love to have the flaps bound correctly to the 3 position switch.
