I bought mine used not so long ago, I guess for the most I knew what I was buying and the price was okay considering it came with the GB603 gimbal an ST24 as well as a ST16 and the ProAction Grip handle.
It is incorrect to say they are no longer selling, they are and it is still listed on Yuneec UK at £3999
Are they still supporting? Well kind of, I took mine into Yuneec UK to have the premature low battery alarm lowered and I asked this very question. They are certainly supporting it at this level and still have spares for the most part.
I don't really understand how they can still market this though with the battery situation as it is, the Yuneec batteries are useless and the listed Tattu's are no longer available. They told me there were some new batteries for the 920 due in, by the time I got there they has all gone apparently and they were £300 each.
What is certain is there will be no firmware updates for the H920+ and while Yuneec UK may continue to support as they are able, support or development from China does not exist, so we have what we have.
There are many threads on here that go into much detail, the H920 is a fantastic platform that with continued development could have been a winner but Yuneec do not work that way.
The Typhoon H was the same, promises of development and cameras blah blah blah that never happen and then a new model and abondon the one you have.
However, the H920 carries a good camera and can create good photos and video, we just have accept this and use it for what it is.
As for me I will not be buying anymore Yuneec products unless proven. Never will I trust to development or updates, sad to say but I may have to start leaning towards big brother.
