In the stick.cfg the bottom 3 lines are the ones that adjust the stick scaling / response curve.
Of these 3 lines the top one is the pitch. Here are my current settings.
0.12,0.34,0.53,0.70,0.84,0.94,1.00,1.00,1.00,1.00
1.00,1.00,1.00,1.00,1.00,1.00,1.00,1.00,1.00,1.00
1.00,1.00,1.00,1.00,1.00,1.00,1.00,1.00,1.00,1.00
The first columns are virtually flat which gives very fine control around the centre point for lining up a target.
Dead band and damping i set to zero however your last post suggets you may need some.
Personally I also always trim my pitch down before fighting, meaning i have to maintain some back pressure on the stick to fly level.
I find it a lot easier to slightly release stick pressure to line up a con quickly rather than stop pulling and then start pushing stick away which i always find leads to over correction errors.
YMMV but given the trouble your having anythings worth a go.
