Can't help directly with a profile for the X52 SST but...
I have the 52 pro too, and after a long time of fiddling & tweaking I came to the conclusion that mapping the stick just in AH was the easier & more practicable solution
This is my AH2 ingame X52 pro profile:
http://www.mediafire.com/?sharekey=4b12b5cc24a8b0abc74f70ddb56f9ac856485f8f05165657A few things to note:
- I use pedals, so no twisty
- I use the pinkie to toggle through AH modes 1, 2, 3. To make this possible, you have to remove all "pinkie+ XXX" modes in your SST profile, if you got any, or AH won't recognize the pinkie as a regular button.
- I use AH modes 1-3 to have different trigger sequences for the two-stage trigger on my 52: Mode 1 = Primary Fire/Secondary Fire, Mode 2 = Secondary Fire/Primary Fire, Mode 3 = Fire all. I switch between modes during flight according to plane & current needs (bombers & GV always in Mode 3 tho)
- Fire C is left unused, it's mapped as my TrackIr recenter button.
