Hi I'm kind of lost .... I'm trying to set the cyclic ring and I'm not sure if my Servos are just noisy or are binding. I can't make them stop buzzing no matter where I set the slider. I have BK 3001 Servos installed, I'm posting a video so you can see what I'm talking about.

Hi,

your servos are not binding, but there is issue with Goblin push rods. If your helicopter is new, they are very tight and you should use ball reamer to get it smooth. Especially rudder is very important, here it should be butter smooth.
When it will be OK servos will not buzz anymore. Now they are trying to compensate these forces all the time.
So basically pushrods should move on its own just by wind to make it perfectly smooth.

It can also affect performance, especially of the tail. I hope it can help you.
