Default Help with squeaking sound

I completely cleaned/replaced all bearings 10 flights ago.

5 flights ago I re-oiled the bearings (scorpion oil)

After the most recent flight (#10) I noticed this weird squeaking that sounds like it's coming from the pulleys in the tail and the frame.

I oiled the bearings again but the squeaking won't go away - so I'm not sure if it's the bearings.

Any idea what is causing this? Drive train feels smooth and I don't hear anything in flight.

What caused this is probably your cleaning and reoiling of the bearings.
Most of the bearings on the mini P are sealed bearings that have enough grease in them for their time of use, and oiling them will flush this grease and they will need to be reoiled very often.
I do however oil my motor bearings every 5-10 flights because the previous owner did as well.

I really don't know what else could cause this noise apart from bearings, since there are no gears.

You are absolutely right

I oiled the bearings again and put a hovering flight on it to work the oil in. The squeaking is gone but I think I'm gonna have to oil the bearings every 3 flights now

My tip - do not clean out and oil old pulley bearings. Just replace them
