❏
10. Install the throttle servo onto the throttle servo tray
using the hardware supplied with the servo. Be sure that the
throttle servo is not touching the elevator servo.
❏
11. Drill a 3/16" [4.8mm] hole in the fi rewall inline with the
throttle arm on the carburetor (an extra long drill bit is very
useful). Roughen the outside of the included outer pushrod
tube using 220-grit sandpaper. Slide the outer pushrod tube
through the hole you drilled in the fi rewall and through one
of the lightening holes in the second former. Fit the plywood
outer pushrod tube support over the aft end of the pushrod
tube, but do not glue it in place yet. Position the outer pushrod
tube so that it protrudes beyond the fi rewall approximately
2-1/4" [57mm]. Glue the outer pushrod tube to the hole in
the fi rewall.
❏
12. Install a brass screw-lock connector onto the second
inner hole of the throttle servo arm using a nylon retainer.
Thread a 4-40 x 1/8" [3mm] SHCS loosely into the screw-
lock pushrod connector. Center the throttle servo using your
radio system and attach the arm to the servo with the servo
arm screw.
❏
13. To make the throttle pushrod easier to work with inside
the fuselage, cut the remaining 36" [914mm] pushrod down to
approximately 21" long [ 533mm] (do not cut off the threaded
end). If you are installing an engine with a rear mounted carb,
also cut off a portion of the threaded end, leaving 1/2" [13mm].
Thread a nylon clevis onto the pushrod 20 complete turns and
install a silicone clevis retainer onto the clevis.
