I'd say just map the axes to your X52 Pro ingame and start playing. After a while you'll notice what commands you use often. This combined with the information from the Flight Manual about the real-life cyclic and collective you can create your own profile. I'm sure that if everyone posted and tried each other's profile we'd all be pretty confused and complain about some (if not all) settings.
I configured my X52 Pro as such:
Axis settings were done in Black Shark.
ALL buttons were assigned in my SST profile as the key strokes that perform each function.
I really think that ED is a wonderful developer here in that they have given every single in-game function a key bind. This makes for very easy profiling - unlike for example IL-2 where almost no function is bound to any key by default, making profile creation for a game like that almost impossible with out a lot of alt-tabbing and messing around with new binds etc...
