Yea, its really just the balde grips that wobble, the blades themselves are ok. One of the blades hit a box in my living room then it twisted around and the blade grip ended up upside down, so i had to take the baldes off and twist it back to normal, that when i founf it to be be very loose. All the links look fine. It spins up (without the blades on) Nothing looks bent. When I spin it up and keep it at almost full throttle and make some Cyclic adjustments, its kinda hard to explain but they react, but it slow motion, very sloppy.

Maybe it is a bent shaft, but i feel like its something else... hmmmm
