smercernary,
Do you mean that the wobble is slow circles at lower throttle or whole rotor disk does circles as though your were moving right stick in slow circles? After numerous "pilot induced" crashes, I've yet to have 4-1 problems. I usually have the stick and trim off immediatly. I have bent the shaft once though and it does make it nearly unflyable. I just ran it up enough to determine the direction of the bend and progressively bent it in the opposite direction till there was no dicernable wobble. I did not disasseble it for this repair. Just held the main gear firmly. Good luck.
