Bought a new Dazzler ARF last evening and am working on hooking up the last few control surfaces. I am using a Futaba 6EXA radio with 4 S3004 (bb) servos for the control surfaces and a JR NES 341 (mini) servo for the throttle (happenned to have it and didn't want to drive to the hobby shop.) The mini servo for the throttle is buzzing intermittently, it is not binding or under any unusual load. Can anyone give me any assistance?

As a side note, The quality of this ARF is excellent.
