LOGO 550 swashplate oscillate problem

Hi
I got my first new LOGO 550 last week and assembled carefully.

Is this a NG swashplate?

thanks

Hi,

seems like it's only starting to happen once the inner ring is rotating.

By our experience it's not a critical issue, and it does not cause changes in the AoA of the blades, does not interfere with control, so most pilots seem to fly nonetheless.

Kind regards

Thank you.
