Before starting the next few steps, please make sure
you have read and completely understood how your radio
control system and ESC operate.
❑
13) Per your radio system guide and ESC instruc-
tions, plug the flight battery into the ESC, then plug the
ESC and the rudder servo lead into their proper slots in
the receiver. Turn on the radio system.
❑
14) Check to make sure the rudder control stick and
the rudder trim lever are centered.
❑
15) Slide the adjustable servo connector/servo horn
assembly over the end of the rudder pushrod wire and
align the servo horn with the servo output shaft.
❑
16) Attach the servo horn to the output shaft, mak-
ing sure that the servo horn is centered and points toward
the fuselage side. See photo # 27 below.

❑
17) Use a couple of pieces of masking tape, taped
between the vertical stabilizer and the rudder, to hold the
rudder centered.
❑
18) With the rudder servo horn centered, use a # 1
phillips screwdriver and tighten the machine screw in the
adjustable servo connector.
❑
19) Using a # 0 phillips screwdriver, install and
tighten the servo arm retaining screw, provided with your
servo, to secure the servo horn into place.
❑
20) Remove the masking tape from the rudder and
double check that the rudder and the rudder servo are still
centered.
❑
21) With your radio system plugged in and turned
on, check the direction the rudder control surface moves
and the amount of deflection. To do this push right on the
rudder control stick. The rudder should move right. If it
does not, flip the servo reversing switch on your transmit-
ter to change the direction. (Refer to your radio guide for
more information on this function.)
ADJUSTING THE RUDDER PUSHROD
❑
22)
Push right completely on the rudder control
stick. While holding the control stick fully right, use a
ruler and measure the amount the trailing edge of the rud-
der moves right. This measurement should be 1" and
should be taken at the widest point of the rudder. See
figure # 9 below.
Figure # 9
❑
23)
If the control surface deflection is more or less
than 1" it must be changed. If your radio is equipped
with End Point Adjustments (EPA), make those adjust-
ments using the transmitter. (Refer to your radio guide
for further details.) If your radio does not have this fea-
ture, you can still make the adjustments to the pushrod
manually.
❑
24)
If the rudder is moving more than 1", move the
adjustable servo connector in one hole toward the center
of the servo horn to decrease the control deflection. If the
rudder is moving less than 1", move the Z-bend one hole
closer to the base of the control horn to increase the con-
trol deflection. When adjusted properly, the rudder should
move 1" both right and left.
