mine see saw's also, but take note that they are still aligned by the shaft paralell to each other and linked together also by the flybar assembly. Ive replaced the o rings a couple of times and it does not take very long before they get gushy again, it hasent really effected the performance of it much but make the cyclic a tad muddy.. And havent experienced it effecting the tracking of the blades whatsoever. Look at your pitch adjusting links, do they seem close to the same length? Have you had the rotor head apart? How tight are your blades in the grips? does it shake when ya spool it up? is there any damage to the rotor blades themselves? you did not mention if you swapped the washers, this can effect the pitch in an individual blade from the other.
The pitch adjustment are close to the same length (not sure how long they should be and if there's such a thing as them being too short), the head has been apart. I'll check that to make sure it's not loose. I did the washer swap out a while ago. It does shake when I spool up. Blades are new. I wish I could describe how much is see-saws. If I had to eyeball it I would say a good 15 or so degrees. But that's a rough rough guess. It's one of those things you wish you would have checked when it was new. I'm gonna head over to the hobby shop and check a new one.
But there seems to be a whole lot of vibration coming from somewhere. Should the head move back and forth, left to right without input? Because when I'm checking my tracking, that's what I'm seeing. It's almost like something is loose, but I know it's not. That's what led me to the O rings.
