Default Stalled Servo (s)

OK guys, just charged batteries in my newest project along with my JR XP662 Tx. Immediately I have two stalled servos. (I can hear 'em buzzing in the fuse.) Considering there is no load on the servo,(control horns not attached yet), why are they buzzing? Wiggling the sticks changes the buzz but it doesn't go away.

Any suggestions?

Bakes,
Are you running 6 volts? if so, perfectly normal behavior and not stalled servos at all. Your servos are on a "hot charge" and are "humming" in response. Put some load on the servos for a second or so, and the voltage will drop down and the buzz will end. This is especially common/normal for coreless ball bearing servos that are so much more sensitive and responsive.

Bakes,
Have an experienced pilot check over your model to confirm that there's nothing wrong, it isnt a binding linkage, etc.

There is probably nothing wrong with your servos. I have a JR 378, and previously had a 631, and have 4 flight packs.

Every one of my planes/flightpacks has at least one servo, usually more, with a buzzing servo. There is no load, and no binding on the servos, in fact, sometimes they buzz when they aren't installed in a plane.

I am told by my LHS that this is normal, something about the tight centering of the servos. Anyways, I have had no problems with battery drain on any of my flightpacks, so I don't worry about it.
