After installing my Gyro-Tech carbon fiber blades all of the vibrations were gone with the exception of a little 2/rev or cabin hop .
I had motorcycle shimmy dampers on the control rods mounted at the scissors the control rods are connected to,that
really helped a lot with the other blades,since then they have been removed. I still had just a slight amount of 2/rev , I
believe that's minimal because of the blades stiffness and the urethane bushing in the mast,The shake has been reduced
to almost nothing by the addition of one shimmy damper to the upper mast its self. The damper has 25 different settings
I have set the damper to about 75% .So between the urethane bushing and the damper I am vibration free Will send a picture as
soon as I go to the hanger.I now can drink my coffee when flying and not see vibration rings in it.I fly hands off for 5 minutes at a time,
.My trim system is the best ever,its the stabilator attached to the rotor head its self
