The AMA manual ACTUALLY says:
"2. ... (c) Not fly higher than approximately 400 feet above ground level within three (3) miles of an airport without notifying the airport operator."
What is SO freakin hard about downloading the AMA manual and just reading it??? You just dig yourself in deeper and deeper...
BTW - if you go to the FAA website, THEY say to limit your flights to 400ft and they AREN'T a private organization
Model Aircraft Operations
"Individuals flying for hobby or recreation are strongly encouraged to follow safety guidelines, which include:
- "Fly below 400 feet and remain clear of surrounding obstacles"
