Hello Wahid,

Yes, the rotor is tilted approximately 4 degrees to the left toward the retreating Blade. In addition I had to apply negetive incidence to cure the problem or tendency of the rotor disc to tilt to the right as it increased
RPM while accelerating the speed of the take off roll. I read that you were having a similar situation on your aircraft. Have you had any luck fixing your problem yet?
