Good points. I fly full scale as well, (light private aircraft) and from personal experience, I still have problems with the simple slip maneuver in RC vs full scale, and this is after over 40 yrs of flying. I know how it works and why. I just can't emphasize enough, what what the 'physical' link to airplane does for you, vs the radio link. And that was the point I was making. It is one thing to know when and why to do a certain thing. It is another thing to actually execute the maneuver. And with RC, we have so little feedback from the airplane to evaluate, beyond what we can see, and some of see better than others.
