PatR, You've rested my case.
Did I? Perhaps provided an appearance of supporting it but certainly didn't rest it. My reasoning is below. Long, but comprehensive.
I was following the 520 pretty closely and was considering buying one. My 480's work just fine but there are some things I need to do better that I don't believe the 480 will ever be capable of, regardless of soft or firmware updates. I also decided I didn't want something that looked like the great pumpkin used in my business, where some operations don't want attention drawn to the aircraft. I've known for some time I needed something with more capabilities than the H-480, was thinking the 520 might fulfill the needs, but found the pricing higher than I thought it should be for what it provided. A couple of early incident reports had some influence as well. Recognizing the "consumer drone" market is well saturated and that further development of "cheap" products in that area is not likely to bring with it any new, ground breaking concepts and features I began looking around at options.
An Inspire-2 would provide the functionality I need but at $6200.00 with an X5 it's more than I wanted to spend and more importantly, it comes with all the DJI "baggage" that rides with all their products. I have an aversion to having my tool supplier telling me how, when, and where I can use my tools, securing a copy of anything I do for whatever purposes they have for that info, and a system screen that gets buried in warning messages. Coming from a very security conscious field I have an aversion to Apps. Every one of them provides external access to your operating system. People can run to DJI and their "total control" policies if they want, and deal with worse customer service than Yuneec if they want, but I won't be one of them-ever. Great hardware for the most part, but at a price that's far more than monetary.
Another option that makes more sense than either DJI or Yuneec products was, and still is, a custom build inclusive of a few specialized payloads that could swap in and out of the system. Another was and is products from two other little talked about manufacturers/suppliers. All of those choices would put a new system in a very expensive price range, well above Matrice level. I would have full control and ownership of the systems but I don't want to spend between $20,000.00 and $70,000.00. I could spend a little time adapting a couple of my other Pixhawk based systems to accept new gimbals and payloads but being quite busy despite retiring from my corporate job, and being a little on the lazy side, I decided the time, labor, and expense (upwards of $3,000.00 for upgrades) of doing so was not how I want to go right now. I can do that later if desired.
As the price of a 920+ has dropped significantly I took another look at it. I seriously doubt will ever see another firmware upgrade because Yuneec's focus is one their 520, but I don't need it to do more than it already can. They could revisit their plans for their commercial/enterprise operations and continue to build on the 920 but they are Chinese and once a Chinese company establishes a course they don't usually deviate. They are very predictable in that regard. The 920 has a 1" sensor, 16mpxl camera based on the Panasonic Lumix GH-4, a bit lower in resolution than the E-90 but more than the CGO-3 cameras. It has a triple zoom, and because of that will provide better close up stills than the E-90 can from the same distance. Images that don't need to be cropped to enlarge them retain their original resolution

It does not generate a curved horizon. It does not log geo positions in the EXIF data but that's not much of an issue as it can use any of the CGO-3 cameras, which returns geo reference in the EXIF data. Having three CGO-3 cameras I can install a Peau 8mm lens on which upgrades the image to equal that of the E-50. The ST-16 employed by the 920 was altered and has map and waypoint functionality and also employs all the other flight profiles included with the H-480. The CGO-4 camera has a vast range of user adjustment while providing outstanding 4k imagery and shoots in true RAW if desired. The 920 can also be fitted with a Sony A7 and with a little work some others. It's plenty large enough to add a custom FPV cam for the pilot. If you know where to look an FPV mount is already available. The 920 is brutally stable in high winds and has no NFZ's. AT $4500.00 for a complete system that includes a very nice hand held gimbal, hard cases for everything, a mounting adapter for CGO-3 cameras, a better battery charger and a couple extra sets of batteries, batteries that use standard connectors, it's only ~$150.00 more than a 520/E-90 package with three batteries. Makes too much sense
for me.
On a side note, unlike others that seem to have problems with every H-480 firmware update, all mine have functioned perfectly so when the next one comes along, and it will come along, I'll review it and decided if it adds anything I need or want and upload or not accordingly. I have no doubt the 480 will continue to be progressively upgraded, it's in Yuneec's best interest to do so. Although it's a bit too complex for new users, at its price point it's a tool that will act as an entry level leader to their commercial products. People have already demonstrated they will buy something they are not qualified to fly and I doubt that will change any time soon, so the H-480 will continue be supported until Yuneec comes up with something cheaper. I'll keep flying my H's but they are a small aircraft and will always be limited in being small. Personally, I don't and never expected the H-480, or anything else, to be all things for all people.
