WL V911 problem

[S_W_A_T_Z]

Ok so I got this thing yesterday and when I took it out of the box, everything seemed to be in order. The motor was smooth, blades weren't warped, and in general it seemed like it was a decent piece of machine....

Well that wasn't the case. I started flying it and while it was in the air something seems to bind. I really don't know what it is and I don't really know where to look. It only seems to happen when the throttle is above half (which could mean absolutely nothing). I posted a video of it below. The vibration doesn't occur until 39 seconds in, but The rest of the video shows that it can fly around with no problem and then it randomly happens. Maybe someone can point me in the right direction?

So........ after a few hours of fooling around I think I fixed it. I took the flybar off and the wings off. Then I found that below the swashplate there is a brace with a single screw. Now when you really throttle it up the screw binds with the swashplate (causing the spasms you see in the video)

How I fixed it:

I loosened the screw just enough to slide the brace down a hair. Then I tightened it up and then I lengthened the linkage rods that connect to the swashplate (follow this vid for trimming, but just do the same thing to both rods

) By doing this I moved the swashplate up just enough so it doesn't catch on that damn brace screw. I put everything back together and made sure my flybar was extremely snug. Voila ! fixed. I'll post a video when I get a chance.

Hi S_W_A_T_Z,

After fixed until now, does it happened again? Just wonder whether it happened due to fault of motor or servo. Mine is having the same problem.
