Hey Custnam,
About the flyrcuseud or whoever they are, there was a pretty severe episode some time back. It involved unsubstantiated claims and counter claims from our forum members and it got pretty ugly. I got enough garbage emails from them that I just blocked them. And I admit that I've slept just fine since.

If you want durable blades with better than stock lift and the advantage of pivoting mounts (called blade grips) I recommend the goodies at Xtreme. I had them. They work. They like the stronger Xtreme 180 ball bearing motors. And they REALLY like the 180 motors with replaceable silver brushes.

As far as those other guys, I've sort of wondered what happened to them. Maybe you should use your money for a significant upgrade and full report back to us!! LOL! In these days of video editing there is no way to know how the test results actually turned out. I have yet to hear anyone who is impressed with their stuff.
