At the risk of going down an even deeper rabbit hole, isn't the AMA trying to distance itself from multi-rotors? I remember reading accounts of AMA blaming the new regs on us. That's probably rightfully deserved, as I'm sure a fixed wing (or even helicopter) that is gas-engine driven is probably not going to be used with cameras to spy on neighbors. Assuming that AMA is really field-based flying at various club sites, with coordinated events, doesn't it stand to reason that their guidelines are expressly against flying over people?
Maybe I'm looking at this all wrong, but the fixed-wing model aircraft that I witnessed at my local RC club years ago would make minced meat out of whatever they hit. They're larger, heavier, faster, more unwieldy, and usually have much more powerful motors and props. Just saying that if the AMA isn't fond of M/R platforms, then why should our smaller, lighter, slower, more nimble, air frames with less powerful motors and plastic props, be held to the same 'guidelines'... at least with regard to overflight of people?
