I disagree with you. I'm based in Australia and I've been one of the first people to start using the ys-x6 system from Zero.
I was previously using a DJI WKM and I can say with 100% confidence, the YS-X6 system is much more accurate, and much more robust.
You're right however in the fact that it doesn't have nearly the documentation it needs. This is all new technology here, and we're all on the forefront of it all. There are going to be bugs and there will be missing documentation. It's just the name of the game. If you want a system that works right out of the box with excellent English documentation, go get yourself an AR Drone.
