Another interesting part of the FAA document, what is hobby/recreational and what is commercial.
Not Hobby or Recreation
Receiving money for demonstrating
aerobatics with a model aircraft.
Why that choice? Who demonstrates aerobatics and where? Is this the FAA looking at vendor/manufacturer employed or sponsored pilots flying demos/competing in events?
In the past this has come up in context of does AMA Insurance, which only covers "recreational use", cover sponsored pilots? The AMA answer has been yes. Like with FPV the FAA seems to have a much more restrictive interpretation of the requirements. Has the infamous "comma" in AC 91-57 come back to make the FAA less then confident on how the "AMA CBO" will set standards?
BTW for those that fly FPV with a "monitor" not "goggles" it looks like you are fine as long as you never look at the "monitor"
