I realized that now that I've been flying for awhile.
-
the wobble could also be caused by a bent spindle/feathering shaft i have expereinced this before and after replaceing the feathering shaft it was a non issue
-
Also, the reason why it stops vibrating at higher speed is that since the gforces becomes greater at higher RPM it counteracts on the vibration that was first caused by either a bend shaft or blades/paddles that are out of track...this would be noticeble if it where out of track by greather than 1mm..

in this video , i noticed that the blades werent perfectly in track, try to trace the paddles as it revs up. you will see it then .
-
if it happens at a certain speed, then i would suspect a slight bend at the mainshaft, and thats a baaad thing! while its unoticable at higher rpm. Please take of the shaft and place it on a flat surface like glastable, with perfectly smoothsurface. Roll it, if it makes a tiniest wobbly sound then its bend..if it rolls with same "tune" then its not bend. Tighten all connections with mainshaft and recheck the pushrods lengths. Good luck and keep flying!
I noticed a shutter and shimmy when you spooled up, my belt cp also does this. If I quickly bring up the throttle to 50% it doesn't, does anyone know why?

You must be check the main shaft, maybe have some crash and this occasion vibration after a coup and is bent

i think your tail rotor is more vulnerable to ground strike...

i mean the tail blade might hit the ground?

May be but i still have no problem with that.
