Hitec HS-55 servo humming
I'm building my first ARF plane which is an FlyFly PT-20 Ryan.
Currently I'm trying to adjust the ailerons servo, which seems to hum. I made a video, can anyone eventually tell if this amount of humming is normal?

this usually goes away after servo has been "worked" for a few minutes.
2. Try removing horn, if AOK, most likely causes:
a) Hinges are not in a straight line, or working freely with perhaps an excess of
glue on hinge(s) which needs to be worked out.
b) Mechanically incorrect. Control rods perhaps not square to horns and
putting incorrect pressure on horn which may cause binding.
c) Servo - Burnout. Cause & Prevention

Try loosening up the fit of your EZ Connectors to the servo arm. From what I saw on your video these are too tight and bending the pushrods.
