I need some technical help. I installed the trim servo in the
empennage to test it out. I followed all the directions in section
11-9 and 11-10. I ran the servo to the full "nose up" position as
stated and set the trim tabs down deflection for 35 degrees.
However, when I ran the servo to the full "nose down" position there was
hardly any trim tab up delection. The right side had some up deflection,
but the left side had none. It appears there is not enough travel in the
servo and related cables. Also, because of the F-1095B Bellcrank
(one cable ahead of the other) when you run the servo to the full "nose
down" position, the left cable stops advancing when it gets close to
the F-1095A Trim Mount Bracket and actually starts to shorten
when it goes below the F-1095A Trim Mount Bracket while the right side
cable keeps advancing. So, you end up with the two trim tabs in different
positions. It looks like the servo should be limited in the nose down
direction so the two cables always advance the same. What
should the trim tab up deflection be? It is not stated in the manual. Looking for help from anybody that can explain this. Thanks, Tom
