RE: Will the disorientation get easier to deal with?
This is all very good advice. I had the same problem when I got back into the hobby after not flying for a number of years. Your eves will deceive you very often especially at long distances and in adverse lighting. For me it helps to keep a mental picture of what the airplane is doing and try to stay with the orientation I think the plane is supposed to be in versus what my eves are telling me. Usually this only lasts for a second or two until I can see the plane correctly. This helps me from over-reacting everytime the plane looks like it's doing something strange.
