ORIGINAL: butters149
i sanded the plasticpieces down a bit, its alot more stable, but i think i like the stability of the stock rotors betters.
Then You didn't sand enough! The grip assembly has to wobble very freely up and down with the flybar; not to the point where the grips assy. can move side to side, but IT HAS TO MOVE PERFECTLY FREELY. You like the stock better because it ALWAYS moves freely, and so wil these is you cut, grind, sand, etc. more off.
p.s. I'm still on my first set of blades with these after almost 3 weeks.
Hope this helps; give them another shot.
