No matter how much I turn the #@$kin links I can't get the blades to track perfectly. I have even sinched the blade grips down to the point where the blades are tight and don't wiggle around and I still can't get the blades to track perfectly. The closest I have gotten them is about 1/4" apart. Will this cause some kind of problem? I only use the 'stunt switch' to check the tracking of my main blades at zero pitch.
