And if folks parked cars the way some land ARFs (or any models) there would be pieces of scrap metal all over the roads and ramps.

The American Way, and I am guilty of this myself, is to over build, over engine and over stress aircraft. Look at our fighters in real life - huge, heavy, able to carry extra ordnance for ground-attack, but usually fast and able to sustain heavy damage and keep the pilot alive. That's our mind set (and not necessarily bad). We couldn't even get one ready in time for WWII because we were making heavy duds and the Wright Brothers were suing anyone with a good idea. Other nations built light, maneuverable aircraft that could dance well but not take a hit. Cars, too. Big, heavy, lots of engine as well as trim and chrome

You could hand out two identical ARFs to two pilots and one would do 10g stunts with 3X larger of an engine than recommended and crack off the firewall at the first hard landing or shed a wing in a Lomchevak while pilot #2 may fly it like he was in it with an adequate engine and never experience a mishap.
