RE: Hand / Eye
For me flight time is all the exercise I do. I'm learning to fly IMAC, and its very demanding - far more than just keeping the plane from crashing. Many times I'll just pick two maneuvers, a center maneuver and a turn around, and just do those back and forth for the entire flight (7-8 minutes). After a while, the corrections become second nature, and eliminate the brains intervention between the eyes and the fingers.
