I have a os 1.08 on with a 16x8 apc. with out the SFG's on it I flyit like a true pattern ship. I throttle back on the down lines, and open it up when I'm level... full throttle passes no problem.
I used Hitec HS945MG's on ailerons, elevators and a JR8611 on the rudder. SWB servo arms, I also sealed all gaps.
With this set up I can do huge jet like loops EZ
If you are talking about the DuBro HD Glass filled plastic servo arms... this may have been the start of you problem. They do not like Ball links! Ball links will twist the servo arms, clevis's will not. The ball part is so far above or below the arm that it twist. This is why I stopped using them.
Try it... hook one up and power up the servo and test it at 1 1/8" arm, it will flex with the ball link. Then try it with a clevis.

Interesting post regarding Dubros HD's and ball links. Seems to support my argument that the Cr@ppy nylon horns as supplied with the F90 are way below spec. This explains why our original F90's fluttered but now do not despite our best efforts when equipped with proper metal HD/giant scale aileron horns. Interesting that Mike suggests metal geared servos - what does the manual say. The F90 manual says 50oz in entry level digis are okay, and it has huge ailerons...Now if only Mike would bother to respond to my comments on the F90 flutter thread in this forum, Mike???
