|'ve fought with this since I started a couple years back. I don't use a neck strap and maybe this is part of my problem. If you grasp the TX and look at the movement your sticks make when you move your thumb, the movements are likely not naturally N E S W but more likely W would WxSW and E would be ExNE. This drives me nuts on final making my left turn ans the plane ballons up on me.

I think the natural movement of a thumb/forefinger grasp would track more along the lines of N E S W.

One other thing that comes into play is the center spring. I've got three transmitters in front of me, My 9CAP supper, a 9CAP, and a Conquest 6 chan. THe Conquest and the 9CAPS are very close on spring tension on the sticks, but the 9CAP is very soft. I haven't flown this TX yet, so I need to see if some stronger springs would be in order. My feeling is that if the springs have more tension, it will be easier to get straigt movement as you will feel the slight resistance when you stray off center.

This is an interesting topic, one I wish I had stumbled across eariler in the game. Changing methods now doesn't seem to work. Old dogs and new tricks.
