servo.s
i have model jr xf 421ex-5 channel radio.,with 537 servo.s. all servos seem to be buzzing even before i connect the control rods to them. i have centered all servo,s with the trim switches but they still buzz as if there is an overload on them.

RE: servo.s
If they are buzzing as in making noise it is normal and is not a sign of any problem. The only way they will not make any noise is if there is absolutely no load on them at all.
