Sorry to hear about the crash Keris. I doubt it's the ZYX. With the right mechanical and program setup, I could never make the tail blow out on my 450 with the ZYX. Tried it on fast backward flight, hurricane, tail slide and funnel. Plus there's so much videos of the ZYX doing extreme 3D.
I do have Spartan Quark and Align GP790. And I've experienced tail blow out on both. But it's not the gyro. It's either binding, too much collective pitch, or not enough tail pitch. Or it maybe just a crappy servo.
