Holy Moly, I started going over my Falcon to get it ready to fly, and found exactly the same thing wrong. One of the tail blade grips is loose, and not just a little loose either. I can move the blade grip in and out about half an inch along the shaft it's mounted on! So it can't just have moved a little in transit, it was just never tightened. The other blade grip is tight. I guess we really need to the think of the Falcon as an ARF or kit, rather than an RTF, given the slipshod assembly. Anyway thanks a lot bjett for posting this. You surely saved me from having a similar incident.

I had the same problem after about 10 flights it looked as if the tail was ready to break, turned out it was the same screws as above had backed out....
