help, Strong vibrations on Enstrom 480
A friend is working on a Enstrome 480 and after they had the rotor blades of it has very strong virbations. The cyclic is moving nearly an inch back and forth. 0.48 IPS @5:22 we got it down to 1.6 ISP @1 mesured with vibres2000 plus, but the vibrations are still there. They bled the hydraulic dampeners but no improvement. Any sugestions? Please sent me an email.
