I have a weird wobble in the head of my Logo 14, which has been there since its maiden flight.

I call it a wobble because it is way too slow to be a vibration. The amplitude is around 5mm right and left in a hover, with a frequency of around 0.5 seconds.

The blades are fairly well dynamically balanced, and I have tried two different sets from the same manufacturer. I have some other 600mm blades I will try in the next few minutes as well.

Anyone else experience this? Any ideas?

Check the STATIC tracking of the blades. If it's more than 1 or 2mm off, then you may have found the reason for the wobble.

If it's the same with different blades, maybe the hub (center piece) is not running true.

are you running a low headspeed? The dampening on the 14 is fairly stiff and will wobble at lower headspeeds.
