3.
Use the radio system to center the servo, then install a 1-inch (25mm) servo arm onto the
servo. If you used the middle location, make sure the servo arm is oriented to the side of
the fuselage that provides the straightest geometry to the throttle arm on the engine. If a
canister is used, orient the servo arm towards the centerline of the fuselage to provides
the straightest geometry to the throttle arm on the engine. Do not secure the servo arm
screw currently.

4.
Secure the quick connector to your servo arm. Be sure to use blue thread lock for a secure
attachment. The order of components is as follows:
o
Quick connect housing
o
Washer
o
Servo Arm
o
Washer
o
Nut

5.
Locate the pushrod that is only threaded at one end. Thread this linkage approximately
halfway into a WHITE ball linkage. Secure the ball link to your engine throttle arm using
the 2 x 10mm screw, 2mm washers (2), and 2mm lock nut. Do not use thread lock on
these parts, as it can weaken the plastic insert in the lock nut. The order of these
components should be:
o
Screw
o
Washer
o
Throttle Arm
o
Washer
o
Lock Nut.

6.
Remove the M3x5 socket head cap screw from the quick connect. Insert the non-
threaded portion of the throttle linkage through the hole in the side of the quick connect.
With the radio powered on, center the throttle servo and engine throttle arm. Use blue
thread lock and secure the M3x6 screw onto the linkage. Check throttle movement and
position relative to stick position and make any changes necessary. Fully tighten the
screw.
Quique’s Tips:
o
Use the shortest servo arm possible while still getting full throttle arm movement on your
engine. Your throttle end points should be around 110-120% when finished with the
installation. A faster servo (like the Potenza DS22209HV) with a shorter arm is preferred over a
slower servo with a longer arm.
