ADJUSTMENTS
1. General fuselage adjustments
Make the basic fuselage linkage connections and adjust-
ments specified in the fuselage manufacturer's assembly
manual. In particular, check that the center of gravity is within
the specified range.
Also make the receiver, servo, and battery connections in ac-
cordance with "CONNECTION OF RECEIVER, SERVOS,
ETC." instructions on page 4.
[!] Be sure to read and follow all of the "(Installation precau-
tions)".
Before starting adjustment, carefully read the "Transmitter
Operation and Control Surface Movement" section below.
(Transmitter Operation and Control Surface Movement)
The following descriptions assume that the transmitter is held
in the hands in the normal position.
a)When the aileron stick is moved to the right, the right wing
aileron is raised, the left wing aileron is lowered, and the
plane will bank to the right. When the stick is moved to the
left, the reverse maneuvers are performed.
b)When the elevator stick is pulled back. the elevator is
raised and the airplane climbs (Up operation). When the
elevator stick is pushed forward, the elevator is lowered
and the airplane dives (Down operation).
c)When the throttle stick is pulled back, the engine throttle
lever arm moves to the slow (low speed) side. When the
throttle stick is pushed forward, the engine throttle lever
arm moves to the high (high speed) side.
d)When the rudder stick is pushed to the right, the rudder is
deflected to the right and the nose of the airplane turns to
the right. When the rudder stick is pushed to the left, the
rudder is deflected to the left and the nose of the airplane
turns to the left.
(Adjustment procedure)
1) Initial trimmer and switch setting
Before making any adjustments, open the battery cover at the
back of the transmitter and set the trimmers and DIP switches on
the trimmer panel to the initial state shown below.
* Turn all nine trimmers fully clockwise (to the number 10)
with the miniature screwdriver supplied.
* Set all the switches (DIP switch No. 1 to 9) to the lower
position.
(Turn on the transmitter and receiver power switches
and make the adjustments described below.)
2) Make the basic adjustments (deflection angle) specified in
the airplane design drawings or instruction manual.
3)Check the direction of operation of each servo.
If a servo moves in the wrong direction, switch its reversing
switch. (In this way the direction of operation can be
changed without changing the linkage.)
[!] Be especially careful of the direction of operation of the ai-
leron servos.
Servo reversing switch
(Setting)
The servo reversing switches (SERVO REVERSER)
(DIP switch Nos. 1 to 6) on the trimmer panel can be set
for each channel.
The lower (NOR) position is the normal position and the
upper (REV) position is the reverse position.
4)Check the neutral adjustment and left and right (up and
down) travel of each servo.
If the neutral position has changed, or the travel is incor-
rect, readjust it by changing the servo horn position on the
splined shaft or by changing the hole position on the servo
horn. (Adjust the neutral position by servo horn position
when the transmitter trimmer is at the center.)
5)Check the engine throttle linkage.
The throttle is opened fully when the throttle stick is set to
the high position (pushed forward) and is closed fully when
the throttle stick is set to the maximum slow position (pulled
back).
6) The throttle or rudder servo travel can be trimmed with the
following throttle ATV or throttle AST/rudder AST function.
Select the function you want to use.
Throttle ATV functioni
(Function)
The high and low throttle servo travel can be adjusted
independently. Use this function to compensate for
throttle linkage variations. The travel rate can be ad-
justed from 30% to 100% of the total servo travel (each
side) as shown in the figure.
(Setting)
To activate the throttle ATV function, set the rudder AST
(RUD.AST) ACT/INH switch (DIP switch No. 9) on the
trimmer panel to the INH (lower) position. (Be aware that
the rudder AST function and throttle ATV function cannot
be used simultaneously.)
* High side travel adjustment:
Adjust the high side travel with the high side trimmer (H)
