I'm not on YuneecPilots anymore, but when I was even the H520s had a long list of weird stuff they did ! And it was very hard to have any faith in a company that constantly looked as if it was on the very brink of death or bankruptcy !
Mostly agree, I had a Typhoon H. It's size & controller were impressive.
Loved the retractable landing legs.
But it was a handful at times.
I'd kinda like a Typhoon 520 just to play with.
