Personally, I would like to rquest that some of the moving parts on the plane models be visible.. one such instance is the leading edge slats on the 109s and Las.. it's a small thing, but it really has some impact on immersion.. It almost feels like EAW, where the planes aren't modelled with any visual aileron/elevator movement..

...
Also, it would be really cool to see better looking tracers.. the smoling trail in IL-2 seems a bit too dark and too thick, but the same trails seem too thin and clean in AH... it feels almost like a grey laser beam..

I wonder if there is any chance of seeing them used with the cool particle system..
