This weekend I plan to buy a new servo and try again.

A few things I remember well: I did tight the wing saddle screws more than usual. I’ve had 6 planes so far and I have never had problem because of tightening the screw.

As for the servo, it’s at the tail of the fuse as I said. It’s only 2 inches from the horn. Everything seems that same it has been since I have the plane (about 6 flights so far). I did notice that the elevators can be flexed with my finger, but when I tried to push the pushrod by hand, it’s a little hard. I cleaned residues of CA between the horizontal stab and the elevator. Maybe I did not realize that before, but the servo does the binding noise even when pushed slightly.

My biggest question is: the plane flew straight and level for 6 flights, why now nosing up?

This weekend I will replace the servo and see how it goes.
