I think it's pretty simple.
Separate hobby and Commercial and do the same for the equipment.
FPV:
Hobby GRADE FPV. .5W max (or what ever allows around a range of 750 feet.)
750 feet is fine for most FPV racing and "hobby interests"
Anything above that rating would need a commercial license. People caught using "non hobby" grade FPV equipment without a license face a hefty fine. (hence the morons causing issues in cities and such)
Commercial Grade FPV:
Distance/wattage to be assessed.
License required, and insurance requiered.
Multirotors:
Hobby Grade Multi's:
>2lbs AUW - no license.. unregulated except the normal hobby FAA/Common Sense rules.
Commercial Grade Multi's
<2 lbs - 55lbs
License required, and insurance requiered.
Over 55lbs needs to be specially approved by FAA.
HOW..is this "simple"????
Are hobby shops, mail/internet ordering, only going to sell "hobby grade" to those without a "license" and vice versa ,only sell commercial grade to those posessing a license???
What about those that order the parts to construct their own???
What about units already owned... are those that have commercial grade, but no license, going to stop using them? I think not.
And the biggest question... what governing body is going to enforce and "fine" what you propose as being "simple"??
THEN you say that those using unregulated hobby grade multi's shall use them under "hobby FAA/common sense rules"...... HAHA good luck on that one.....this is why we are in the situation we are today........NEVAGONNAHAPPEN.
Steve,,,, what you suggested actually creates more questions than solutions....much less "simple ones"
What solution is there???? maybe regulating "how and where it is legal" to fly them???? but that creates enforcement issues too.
Banning them?? not gonna happen either, Plus there are already too many out there.
This is why there cities, municipalities, federal parks, state parks, county parks, and even a few states banning/proposed banning R/C as a whole.
Why are they doing this??? because in a few instances they wanted to ban multi's, but the owners of the multi's cried fowl as they claimed they fly as a hobby, so in order to not discriminate, they Ban all R/C aviation........ it's happening everywhere.
Little by little we are losing flying areas because of those that "lack any form of common sense"... and they basically DO NO CARE, as they do not like being told what they can/cannot do , or what aircraft they fly.
This balloonhead (government employee, none the less), flies his multi, at 3 in the morning, in "no fly" airspace, crashes on the Whitehouse lawn, AND claims he is a hobbyiest just testing how it flies in bad weather. ( if you believe that, I got a beautiful vacation spot to sell you, 50 miles east of Key West , Florida that is great for fishing.
