Forgive the following question, since this is after all the Phantom Pilots forum...and this does not regard Phantoms but does regard Rules and Regulations... Okay, talking commercial use here. It is clear that aircraft with a takeoff weight between 0.55 pounds and 55 pounds has to be registered. It is also clear that the Part 107 rules regard remote aircraft under 55 pounds (nothing about 0.55 pound lower limit there...that I can find?). So, say you have an "all up" 8-ounce camera drone to supplement your very nice Phantom, do all the 107 rules still apply? Just checking. As background, I do have my "107" and have been doing real estate photography and videos for several years. I have long been equipped to do what used to be called "elevated photography," and still have some really expensive telescoping masts with remote view cameras. Except for one 35-footer in a PVC tube I carry on top of my little SUV at all times, I don't use that stuff anymore. Got my P3A and my older DJI F550 and a homebuilt drone, too - all registered now of course. BUT, now - just for "quick" spur of the moment shots, I bought a tiny 125 dollar HD Video 16MB still camera quad to create decent photos (read editable and clean, not National Geographic) which weighs only 245 grams or about 0.54 pounds. To clarify, this would be for shooting things like low-to-middle priced properties as a free add-on for client good will - that extra 5% effort - (so I can get a great listing assignment later on). It is cool, has the RTH feature, etc ...but it is a feather. Part 107 still applies in every way? Kinda nutty to ask for authorization. Really? Again, please forgive the non-Phantom and probably silly question, but this IS the Gold Standard drone forum after all.
