1) Locate a plastic servo arm that came with
your servo. Using wire cutters, remove all but one of
the arms.
q
2) Install one adjustable servo connector
through the third hole out from the center of the servo
arm. You will have to enlarge the hole in the servo
arm using a 5/64” drill bit so the servo connector will
fit through. See figure # 6 below.

q
3) Plug the throttle servo lead into your receiver
and turn on the radio system (please refer to your
radio system manual for complete instructions about
connecting and operating your radio system).
q
4) Check to ensure that the throttle servo output
shaft is moving in the correct direction. When the
throttle stick is moved forward, from idle to full throttle,
the output shaft should rotate counterclockwise.
q
5) Slide the adjustable servo connector/servo
arm assembly over the plain end of the throttle push-
rod wire. Position the throttle stick and the throttle
trim at their lowest positions.
q
6) Manually push the carburetor barrel fully
closed. Angle the servo arm about 45º back from
center and attach the servo arm to the output shaft.
The servo arm should be pointing toward the fuse-
lage side. With the carburetor barrel fully closed,
tighten the set screw in the adjustable servo connector
using the Allen Wrench provided.

cutters and install the servo arm retaining screw.
Tighten it securely. See photo # 26 below.

ADJUSTING THE THROTTLE LINKAGE
q
8) When the throttle linkage is adjusted prop-
erly, the carburetor barrel should be fully closed when
the throttle stick and the throttle trim lever are at their
lowest positions. Moving the throttle trim up should
open the carburetor barrel about 25% - 30%. Mov-
ing the throttle stick all the way forward should open
the throttle barrel completely. All of these move-
ments should be done without any binding in the
linkage. Sometimes the servo will bind at either the
fully closed and/or fully open throttle positions. If
this happens, and your radio is equipped with digital
or manual end point adjustments, make those adjust-
ments using the transmitter (see your radio instruction
manual for further details). If your radio does not
have this feature you can still adjust the linkage. For
more linkage travel, move the adjustable servo con-
nector to a hole farther out from the center of the
servo arm. For less travel, move the connector to a
hole closer to the center of the servo arm. Ideally,
you don't want the servo to bind while at idle or full
throttle. This would cause excessive strain on the
servo and would also cause excessive drain on the
battery pack.
