100Mbps is far from broadcast quality very far from broadcast quality. our lowest data rate for 3.8K on the Arri Alexa is 340Mbps usually non vex shows record at 734Mbps (ProRes 444HQ) and VFX shows will record at 4444XQ at 1650Mbps
Yes, but those are raw (lossless encoded) file sizes, aren't they? And remind me how much the Alexa costs?
I'm not sure what you're trying to prove here. The Typhoon, GoPros, Phantoms and other similar equipment use physically small sensors and write to single SD cards. That puts a hard limit on how high a bit rate you can generate and how much noise you get from the camera. Codecs can help get around that, and a good codec will improve the quality you can get from your hardware - but you're absolutely right that if you compare the Typhoon to a camera that costs twenty times as much, it's not as good.
However, the quality is more than good enough to use online - YouTube, Vimeo etc. And as others have pointed out it's 'good enough' to be used in TV broadcasts in the right circumstances. Would I use it to shoot a feature film? No! Would I use it in a short? Quite possibly. Is it about the same as equivalent cameras from other manufacturers? Yes, and in some circumstances it's better.
So whilst there are some issues that Yuneec need to address (120fps encoding and some people suffering soft focus), the basic platform is completely sound. Encouraging people to panic because their camera doesn't match up to professional broadcast standards is really unhelpful. There are people in this forum looking to invoke consumer rights protection because some magic number that they don't understand doesn't match up to another number that means nothing to them. Is that sensible? Are either of those numbers absolute measures of quality? No they're not and I think a professional like you should know not to pretend otherwise.
The bottom line is for a thousand (ish) bucks, you've got a hexacopter, base station and camera with a good quality gimbal. You can absolutely get it out of the box and produce a video that will be good enough to show on TV. If you thought it was going to turn you into Spielberg, you're going to be disappointed. It's up to Yuneec to address the outstanding concerns, but there's no reason to think they won't, and no reason to think that this isn't a lot of kit for relatively little.
