Make sure the model cg's on the main shaft before each flight, being nose or tail heavy can lead to porpoising in fff.

Worn dampeners or sloppy swash can lead to similar issues.

Try raising the P and I gains for both roll and pitch cyclic to 70.

Let me know if the issue has been reduced.

SAFE->Attitude Trim is used to trim the attitude in SAFE panic or stability modes. Defaults of roll = 450 (4.5 degrees) and pitch = 0 are correct for most clockwise rotating helis.
