You've given us a Su-26. . . why don't you give us a Red Bull style air racing track. Maybe a section of the Thames with a lot fewer buildings and some pylons. Something to get us into the mood for air racing. I'd also love to see who'd win between a Su-26 and the best the RAF/Luft has to offer.
Another idea is a map with some geography to make things interesting. I'm talking about a small map with some canyons, some cliffs, mountains, valleys, and maybe even some high and low bridges that we can go through. Anything to make low-level dogfights more interesting. Basically I want a map where if you're right on a guy's tail and too focused on your cross-hairs he's going to lead you right into the side of some manner of landmass or structure.
Think of the opening of Jurassic park when they are arriving at the Island by helicopter. I want a treacherous landscape that is more dangerous than the people you're flying against.
