Actuall RAM,, it sounds as if your stick may have developed a "Positional Spike"
If you are not doing anything differently than prior to your wingloss,, then something in the hardware is screwy.
Just recently I began losing B-17 wings when I shouldn't have. Doing some investigation, I found that at a certain point in my stck travel, I'd get a massive spike. (I use a PPro USB).. Pot cleaning fixed the prob.
Give it a try,, it may take ya a day or two to find it,, but it's there from the sounds of it..
