❑
Remove the throttle arm from your engine and install the Z-Bend in the pushrod wire into the outermost hole in the
throttle arm.
☞
You may need to enlarge the hole in your engine's throttle arm, using a 5/64" diameter drill bit, to accommodate the wire.
STEP 2: INSTALLING THE THROTTLE PUSHROD WIRE & ADJUSTABLE CONNECTOR
❑
Slide the plain end of the throttle pushrod wire into the
nylon tube in the firewall, then reinstall the throttle arm onto
your engine.

So that the pushrod wire doesn't bind, you
may need to make a bend in the pushrod wire so that it lines
up better with your engine's throttle arm. It may help to have
the longer portion of the pushrod wire toward the inside of
the throttle arm, too.
❑
Using a modeling knife, cut away all but one arm from a "4-point" servo horn.
❑
Enlarge the hole in the servo arm that is 9/16" out from the
center of the servo arm, using a 5/64" diameter drill bit.
❑
Install the adjustable servo connector into the enlarged hole.

When threading on the connector nut, don't
tighten the nut completely. You don't want the connector
loose, but you do want it to be able to rotate without binding.
To prevent the connector nut from loosening during flight, apply a drop of thin C/A to it. Allow the C/A to dry
before proceeding.
❑
Connect your radio system and plug the throttle servo into the receiver. Check to ensure that the throttle servo output
shaft is rotating in the correct direction. When the throttle control stick is moved forward, from the idle to the full throttle
position, the servo output shaft should rotate clockwise. If it doesn't, flip the servo reversing switch on your transmitter.
❑
Position the throttle control stick and the throttle trim lever on your transmitter to their lowest positions.
❑
Slide the adjustable servo connector/servo horn assembly over the plain end of the throttle pushrod wire.
PRO TIP
❑
After making sure that the carburetor is in the fully closed
position, angle the servo horn back about 45º from center and
attach it to the servo output shaft. The servo connector should
be facing the side of the fuselage, as shown.
☞
You may need to make a shallow bend in the pushrod wire
near the servo arm, so that the pushrod lines up better with the
adjustable connector.
❑
While holding the carburetor barrel fully closed, install and
tighten the grub screw in the top of the adjustable servo connector.
