any ideas?
Thanks!!

Is it powered by a switching BEC?  Maybe electrical noise.  Maybe bad clone FC.  Is there an FPV transmitter you could try turning off?

Do you have another CC3D that you could try those exact same settings (including calibrations) for a test?  Export to uav file and import from that uav file.  Not to fly it with wrong calibrations, but to see if it might be hardware related.

You could try disconnecting things to see if a particular component causes the issue.  If you get everything disconnected and it still happens, post the uav file here and we can try it to see if it happens.

My bec is linear,
Im pretty sure its an original one because until openflight changed to librepilot it worked fine (ive had it for more than a year now), it was bought from survielzone.

Tried to turn off the video transmitter, didnt help.

I dont have another one to check.. im starting to wonder if i should just change an FC..

What is the uav file?

With USB plugged in, GCS -> File -> Export ...
writes all the FC settings to a filename that ends in .uav

File -> Import will get those settings temporarily into FC and has an extra button after selecing file, to save them into FC permanent storage.
