❏
12. Position the servo tray with the arm on the servo so
that it is in line with the carburetor arm.
❏
13. On the firewall mark the location of the two holes you
drilled in the servo tray. Drill through the marks on the
firewall with a 1/8" [2.8mm] drill bit.
❏
14. Install 4-40 blind nuts inside of the fuselage into the two
holes you drilled. (Note: Because there are lightening holes in
the firewall former it is possible that you may only drill through
the fiberglass and not the plywood. If this is the case, drill a 1/8"
[2.8mm] hole through scrap plywood and insert the blind nut
into it. Then, place the plywood in position on the firewall. DO
NOT try to pull a blind nut through the fiberglass.) Mount the
servo tray to the firewall with two 4-40 x 1/2" [4-40 x 13mm]
socket head cap screws and #4 washers.
❏
15. Cut off the threaded portion of a 6" [13mm] wire
pushrod. Make a 90 degree bend on the end of the wire
leaving 3/16" [4.8mm] extending from the bend. Install a brass
quick connect onto the throttle arm using the nylon retainer.
Enlarge the first hole in the servo arm with a Hobbico Servo
Horn Drill (or a #48 or 5/64" [2mm] drill bit). Insert the straight
end of the wire into the hole in the brass quick connect. Insert
the opposite end through the hole in the servo arm. Install a
nylon Faslink onto the servo arm and then center the servo.
Center the throttle barrel and then tighten the 4-40 x 1/4"
[4-40 x 6mm] socket head cap screw onto the wire.
❏
16. Cut a small opening in the firewall for the throttle
servo wire to pass into the fuselage. Be sure you position
the opening in a place that will not obstruct the installation of
the fuel tank.
❏
1. Assemble the fuel tank as shown in the sketch. When
tightening the center screw be sure not to over tighten it. You
just want it snug enough to pull the rubber stopper tight
against the tank.
