Yes indeed Don, I know exactly what you are saying, and when that plane fly's away from you and gets too far out, orientation becomes a real problem. I have witnessed many crashes from this very problem, majority of time from learning students.
Our Club does a local mall show mostly every year. We set up a flight sim for those interested. This guy about 40 comes over with his son, tells me his son would be able to do this with no problem. The father said he play all kinds of video games, so he could handle it.. So as I chuckled to myself, ok I said, I set him up on a trainer plane like a top wing Cessna.
I gave the kid the controls, and explained to him that when he moves the gimbles on the transmitter what each one operates, he say's no problem.
Well He never made it a quarter down the runway he kept nosing it into the ground. 5 times he did this, then the grand finale came about he was able to run it down most of the runway he went up to fast had a stall smaaash! right into the ground.
His Father grabbed the TX from him, clunked it down on the table and left.. There was a few of us had some laughs over that. They both found out , it wasn't that simple after all.
We have some guys who fly full size in our clubs, like Cessna's. Who will tell you it's more difficult to fly R/C than their planes, some of the reasons being,
1. You are not in the aircraft
2. Orientation of plane , Knowing when its in upright or upside down. Orientation is crucial. When you become more experienced this drops off. But never the less, if you don't remain focused , it will come back to bite you, I know from personal experience. If I get to the field and I feel tired, I DO NOT FLY
3. When plane is coming toward you right on the gimble is left and left is right
4. Not sure why, there are a few Pilots that have trouble making right hand turns, in fact there is one guy I know who has flown for years who cannot make right hand turns to this day..
