Splined Horn And Frequency Channel No. Flag Color; Splined Horns - FUTABA FP-8SSHP Instruction Manual

SPLINED HORNS

The splined horns allow shifting of
the servo neutral position at the
servo horn.
Setting and shifting the neutral
position
a) Angle divisions
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 in
the shaft. For four arms, the
minimum adjustable angle is:
25X4
360 :
Number of divisions
The following splined horns are optional.

Futaba Digital Proportional
Frequencies (FOR U.S.A.)
•The frequency of Futaba digital proportional
sets can be changed among bands (1)~(6) on
the 27MHz band only.
• However, a 27MHz band set cannot be changed
to 72MHz band, and vice versa.
• Therefore, always attach the correct frequency
flag to the end of the transmitter antenna. Each
frequency band has its own designated color, as
stated above. The frequency flag is intended for
identificantion purposes.
• Also change the frequency flag when frequency
is changed.
• Futaba paired crystals are precisely matched.
Always use a Futaba crystal set (transmitter,
receiver) when changing the frequency.
• It is illegal to change crystals of transmitter on
the 72-75MHz bands in the U.S.A.
b) Effect
To shift the holes center line "o the
Fig. 65
right (clockwise) relative to baseline
A, shift arm 2 to the position 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)
To shift the same angle in the op-
posite direction, use the opposite

arm number.
HORN B HORN C
Baseline A
For a six arm horn, turn the arm
counterclockwise and set arm 2 to
the position of arm 1. The adjustable
Fig. 66
angle is 60° - (14.4 x 4) = 2.4°.
Arm 3 shift 4.8° to the right, arm 6
shifts 2.4° to the left. and arm 4
shifts 7.2° to the right and left.
