I sure wish the RC world could start using the terminology General Aviation GA uses for themselves. As both a GA and RC pilot... I just shake my head. It is like a foreign language. There are many GA pilots who fly both aircraft types. RC must give right of way to GA no matter what is happening. Moving a flying site is not a practical solution given the expense of creating the field and facilities. Come on, we both don't want any collisions so spotters are necessary. I fly telemetry in one of my RC planes, 400 feet is a lot of airspace. Not for everyone, but for most.
