Servo tail jitter problem

Hi there! And hello! I'm new on the forums.

I've just assembled my tricopter last week and was starting to learn to fly. But since then it has developed a vibration in the tail that I have just this evening isolated to be related to the tail servo. I am aware of the jitter from an unfiltered servo and had set the servo filter setting on the KK2 to 30 as recommended. This issue seems to be unrelated and persisted when I upped that value to 40.

Then I tried disconnecting the servo, and hey presto! The vibration was gone. See the short vid below.

I'm using the BMS-385DMAX Digital Servo (Metal Gear) suggested in the original 2.5 build instructions. Any idea what it could be or what to try next? Thanks!
