Ok I have a gy240 gyro. which i believe is a HH. Ill have to check everything you guys said 2 of the pins in the tailroter were sticking out a bit so I pushed them back in. It seemed to help a little bit. there is no vibration in the tail like up and down when its still on the ground when i first power up there is. then when I increase the throttle right before take off it stops. then when it gets in the air it starts again. How do you balance the tail rotor? I looked in the manual but didnt see anything.
The trim is fine I corrected it. At low head speeds the entire frame shakes side to side like the main shaft is bent. Ill have to take it off and see if you guys have anymore advice feel free to post thanks.
