try replacing the servo with one of your other servos and see if it is the servo. Most likely, it is the servo.

Most probably servo - they do not have much life in them. I changed 3.

Sound like you got your money worth from that servo. Probably the servo is finished. I was having a problem with my servos I though until changed my rx an guess what it turned out my rx was bad. I changed 2 today an the 3rd started acting up, but until they started tripping everything was fine. When 3rd one started tripping I knew something else was wrong when I switched rx 3rd was acting normal again. There is a thin line between everything work great to everything going bad an one thing can cause big problems.

Any other servo option, not to use Walkera? The servo mounting is unique.

Servants tend to rebel after a while.

Der, eh I mean servo's tend to fail after a while.

I am using the servo of the CB-100 or 4#3b for the tail as per Timewerx suggestion it works well.

Vronny,

What made you think that it was the Rx?

My V120d01 started with tail wags. I installed the CB-100 servo it felt better for a while but then started again. I then replaced the tail shaft. It felt better but was still wagging.

I tightened and loosened the blades no with no real impact.

I replaced the main gear. The pin was loose because theplastic where the pin enters broke.

I removed the servo rod and and pushed the throttle stick it was smooth.

I connected the push rod and removed the main blades it was smoth. Moving the stick left to right the heli started shaking.

Any ideas of what could be bad? I hope it is not the Rx.
