I've had my eye on this frame for some time now, and when Amazon put it on sale I jumped at the chance to build it.
The frame is a true X with 5mm thick arms that will swing 5.5 props. The cage is tall and allows for 30x30 / 20x20 multiple stack builds. The center of the cage is printed with PLA and needed to be heated a bit to make it easer for the standoffs to push through. Overall I'm happy with the way it flies and I'm looking foward to some more flights in better locations in the weeks to come.
