I dont find the AHII FM's all that hard to fly, but then again I dont fly the Niki or the La7 or any version of the Spit so I cant comment on them, and I dont use the "gamey helocopter" moves either. I can say that most planes I fly still fly much like they did, although all planes do seem to stall easier.
Gunnery also seems easier at close ranges, but harder at long if that makes any sense. Here is an example, last week I was up and flying the 109F, I pulled up to shoot a P-38 at about D400. Usually at that range I pull what I think is the proper lead and adjust with tracers, well, before I could even decide if I needed to adjust the 38 blew up. Granted, I had gonds, and I might have gotten the perfect lead right away (which I dont usually), but it seems that in close gunnery is both easier and more lethal. It could just be my imagination too.
