Default 7955tg -jittering-should I be concerned?

Just put two HS-7955TG servos on the elevators of my 35% Extra and they must be nervous because they have some amount of noise and jittering when at neutral. They operate fine through the entire range of motion and are responding perfect,they just act like they are continuously trying to find center.
I understand that this is not uncommon,my only question is are they safe to fly?
Thanks

If the jittering disappears when you stand the plane up (i.e., to cancel the weight of the elevators on the servos), then it probably is safe to use them. Are these servos in good shape otherwise, and the dead-bend is set to the minimal?

yes it will almost go away when I stand the plane on its nose. I may have used the wrong word "jittering". it is more like a buzzing noise.

Analog servos "Buzz". Digital servos "Whine". That is normal. This usually happens under load, but can occur at Neutral.

They are VERY sensitive to holding center. So sensitive that the weight of the elevators are causing them to want to fight (slightly) to hold center.

I am the Secretary of the Radio Control Club of Rochester (RCCR). Our main field is located in Northampton Park between Salmon Creek Rd and Sweden-Walker Rd (Rt 260). This is half way between Spencerport and Brockport, off Rt 31.

This is a public park, but we maintain the runways and pit area. All you need is an AMA Licence to fly there, so you do not need to belong to a club, however, non of the amenities would be there if it were not for our club, including the mowing of the runways and pit area.

We also have a private club field, off Ridge Rd West, which we use all year round. Northampton Park is only open from May until the first snow.

Our club web site is www.rccr1957.com.
