I'm not all that sure they did. Glueing gear together when a new leg can be installed with a couple screws makes no sense. That was a home repair. Having several experiences with Yuneec's CS I know what has been presented in this thread is not consistent with how they work.
When the H first came out I saw a thread at another forum where the OP posted pictures of a broken H. Said it arrived with broken landing gear, broken gimbal lock, rubber finger grips that had fallen off the -16, and other defects. Since I already had one I knew the grips could not fall off and had to be pried off. I just happen to use the same adhesive material that secures the grips to the -16. It's plenty strong enough to secure a flight surface servo in place for 100+ hours. The gimbal lock had to have been forced open and pulled apart at the top to break it. The shipping box was more than adequate to prevent the gear from breaking in transit. Later it became evident the OP was a staunch DJI user and supporter. There has been and continues to be efforts by DJI to discredit the H when and wherever they can. RCG, Facebook, YouTube, Yuneec Forum, here. It has been rampant. DJI people at RCG are mining negatives about the H from this site to post or reference at RCG. That the H has turned out to be a very capable and extremely stable camera rig troubles them greatly. Should the 520 work as advertised their troubles will only increase.
In short, until I see RMA's from Yuneec describing the issues I'm not buying the story. Yuneec references the reported problems on their RMA's. Anyone can take pictures of something broken and say someone else did it. I don't believe everything I read, and even less of things people say.
I'm not saying you're wrong and my personal CS with Yuneec has been stellar but as someone who owns the whole fleet of enthusiasts UASs from both companies, as long as you don't have a problem, DJI innovates and makes better products. It's just a fact. I know it's actually an opinion but DJI is not even worried about Yuneec, even if the 520 delivers. Even if it does deliver, it's biggest problem is it's delivering with the CGO3+.
Yuneec would be wise to release a new camera that doesn't need to be sent to somewhere like peau to even be useable.
25bps for Gorgeous or whatever it's called. I absolutely love and enjoy flying my H and like the form factor (not because of redundancy) as I've never had a crash because of a failing motor on a quad but that said I just enjoy flying it more until I can't get far with it and I also after all this time am still uncomfortable with the ST16. Too much software to feel safe and I'm also a freestyler so I'm not afraid to have a big remote with lots of buttons but too much software.
You might be right. Not saying you're not but that person is wasting their time. DJI owns the world right now. Their evaluated market cap if they were public is about 18x that of GoPro. Don't think they are sending trolls out to websites. They are busy not only innovating after other products, they continue to out do themselves.
The P4P shoots with a much better camera at 100mbps, not to mention there lines of SSD cams that shoot at 3.6gpbs which can make real footage comparable to Alexas and Reds.
Sorry, I know it's not a popular opinion here but there is no comparing (at the moment) Yuneec and DJI. It's like Honda and BMW and that's being generous.
Again, not saying you're incorrect but DJI needs no help winning the race of UASs. The first 4 rounds are over and DJI won all 4 and this one might be a TKO. And I AM A FAN BOY, I own all types of brands and have loyalty to one.
I know some of the real specs coming on the P5 and Yuneec is going to have to do a LOT better than the 520 to compete.
