Seth with your setup wouldn't that mean if the servo was in the stab you would have to tilt the arm back?You could just flip the servo to the top meaning in the stab and the end of the servo arm were the linkage connects would be the same distance from the stab.I'm trying to make sence of it because I always setup my stuff like extra260 does and my stuff is always the same length and square.My end points are the same also meaning up is the same as down.I don't program the servos i do it in the radio and match-em. |

No, Unless you mean parallel to the hinge line. Because the servo is rotated 90º
With the fuse mounted elevator servos, in the bottom portion of the drawing (incorrect way, mounting the servo arm 90º to the case), the arm and linkage straightens out very quickly, ending your travel, which differs from when it is pulled away from the horn, which pulls more throw much faster. Basically, you have 30º of up elevator, with 70º of down elevator (just random numbers), but yet in the same amount of time.
Basically, the same reasoning as to why your linkage isn't 90º to your servo arm on your wing mounted aileron servos, or stab mounted elevator servos. More travel.
Basically, its just offset to equal your travel in the same amount of time between your up/down throw.
Hope this makes sense.
