If you have a sim, then turn on smoke, and fly the plane so that it is a DOT in the simulator.

Learn how to tell which way the plane is oriented and it's attitude by the way it is reacting to the sticks.

Eventually turn OFF the smoke and do likewise.

Once this becomes second nature to you, you'll find that your orientation skills will drastically increase, and you be less prone to "loose it" when flying your real RC planes.
