I have not tried playing with other aircraft but I get a lot of CTD's with the A10C, can't pin down why the only common theme is that there is a massive stutter just before the crash, game freezes for a few seconds then starts going again but almost immediately CTD sometimes it's 5mins into a mission other times 20mins. Only the last 2 ( I think ) of my logs will be from 1.5.2 because I stopped playing for a while to see if this would be sorted, apparently not. the earlier logs from 1.5 and 1.5.1 are exactly the same though ( at least the in-game side of it, exact same CTD ).
