I was also curious about the mention of commercial model aircraft. I guess that if someone was using (and getting paid for) a heli to video at a wedding, the FAA and not the AMA would need to regulate that, right? AMA insurance, as it discludes commercial flight, would be null and void, right?

What about a competitive pilot that competes for a cash prize? Is that not a commercial pilot and commercial aircraft? Would not only the competition, but all testing of that model be FAA regulated, by what DB's article said?
