I sometimes still find myself in that "Left-Right Turn" confusion stage, so I took some fluorescent spray paint in the most vivid red and green I could find and painted a 4" wide swath on the appropriate wing tips for my trainer. It's a 72" wing, so I had plenty of room to work, but the 4" width is highly visible and in nice proportion to the rest of the wing.

Now, no matter which way the plane is heading, I don't consider left or right. I have a visual reference that determines which way the sticks go. When I want to turn to the red side, I know that I must move the sticks left and vice versa for the green side. Problem solved.

Now I'm thinking as I'm sitting here typing that perhaps a similar swath on the stab tips might be helpful to determine aspect, at least until I get more hours under my belt and it become second nature...
