mec,

what servos are those on your elevators?, and since you can read german, what are the recommended servos? The torque rating. Also that control arm looks very short, the arm on the servo too..........

gwright,

what do you think about that? Isn't it better to use longer arms, on both sides, even if the geometry is such that the travel is the same as with the shorter ones? Generally we use a longer servo arm to get more throw, but I have been told that you should use a long arm, (and long horn on control surface) even if its not set up for more throw. I remember with the midwest cap, they said under no circumstances, should the pushrod attach to the control horn less than 3/4" from the surface.
