This horn permits shifting of the
servo neutral position at the servo
horn. Setting and shifting the
neutral position
a) Angle divisions
Fig. 18
1) The splined horn has 25 seg-
ments. The amount of change per
segment is; 360 /25=14.4°
2) The minimum adjustable angle
is determined by the number of
arms or number of the holes. For
four arms, the minimum adjustable
angle is:
b) E f f e c t
Fig. 19
To shift the holes center line to
the right (clockwise) relative to
baseline A, s h i f t arm 2 to the po-
sition of arm 1 and set it to the
position closest to baseline A.
[Example] For a four arm horn,
the angular shift per segment is
14.4°. The s h i f t to the right is 90°
- (14.4 x 6 ) =3.6°
To s h i f t by the same angle in the
opposite direction, use the oppo-
site arm number.
Fig. 20
Arm 3 shift 4.8° to the right, arm
6 s h i f t s 2.4° to the l e f t , a n d arm 4
shifts 7.2° to the right and left.
For a six arm horn, turn the arm
counterclockwise and set arm 2
to the position of arm 1. The ad-
justable angle is 60° — (14.4 x 4)
=2.4°.
