Looks to me like this thread has opened up a lot of the old crap. The way I see it, and yes, I will be blunt since I can is:
1) You fly over 400 feet, you risk getting busted by the FAA, regardless of what the AMA says
2) YES, THE AMA OFFICE IS TRYING TO DECEIVE EVERYONE TO KEEP THEMSELVES RELEVANT IN THE EYES OF THE MEMBERSHIP
3) You want to fly over 400 feet, you probably need to qualify under part 107
DOES THIS WORK FOR YOU SPEED?
