I'm having a somewhat similar problem. I'm using an X52 Pro, and the collective seems to be incredibly over sensitive. The slightest nudge on the throttle produces an incredibly large change in the collective - seemingly from minimum to maximum.
I'm using the same profile as I did on BS1, and I've checked in the options of BS2 to tune the Axes, which seem to be fine, as well as making sure that the controls are correctly assigned. Visually in the cockpit it's OK as well - fully advancing the throttle shows the collective fully advancing at the same rate, and vice versa. However, the control response is just crazy. I can't maintain any kind of level flight - I'm either climbing rapidly, or descending rapidly.
Any ideas?
Cheers,
Ben
