Gee, "take off and landing." What's that all about? Can't accomplish that at 500 ft.

The word that comes to mind with me, is "importance." And I've seen this a number of times with R/C modelers.
Some just think what they do with their models is more important than what a pilot has to do with his aircraft.

Sensible life long Pilots like myself agree, we cringe when we meet a fellow pilot with an Ego.

The same is with R/C modelers, ego's can be dangerous. Piloting aircraft has risks and so does R/C modeling.

With my life long background in General Aviation, and modeling, I can conclude that there should be no arguments or disagreements here. Investigators are being polite.

Some things are just obvious.

I've learned a great deal from reading these comments.
