any slight off-balance rotor wiggle will be magnified at a given RPM when it is at the same resonance frequency as the rotor shaft/shaft material.
meaning: everything has a point where it wiggles best. It would be worse if the blades were even more off balance..but consider it a speed wobble. You probably won't spend much/any time at that rotor head speed.
could be that the main gear isnt pushed in tight

yeah its either a bent shaft or your blades need to be balanced

Looks like a bent outter shaft. Could be both inner and outter are bent.

looks like the main shaft is bent to me

Hope that answers it for you.
