Something I think would help all RC pilots in their flying is to sometime go and take an introductory lesson with a fullsize flying instructor, and go fly a landing approach for real.

The difference between airspeed and groundspeed is very clear when you can feel the air on the plane, hear it outside the window, and see the airspeed indicator on the panel... and you can see the ground sliding past doing its own thing.

Most RC pilots fly too much by ground reference, and not enough by attitude and power. The plane can't feel the ground OR the wind, all it notices is the relative wind where it is. So if you fly attitudes and power settings, and then adjust to create the path you want, you're flying much safer... like a fullsize pilot does.
