I too had to trim the bits around the elevator servo horn to get decent throw, else the horn strikes the FG skin. In fact, I found that I had to turn up beyond TX 100% of normal limits to get good throw angles of the stab. Without, the maximum throw +/- is around 10-12 degrees. I managed to push it up better to about 24degrees now. Good to have the stretch, whether I will need it or not, remains to be seen.
As for the rudder servo installation, that was painful for me. I found that I had to raise and tilt the servo at a particular way in order to get the rudder removable.
I had no good technique, trial fitting all the while until I got it. It took me many many attempts.
