3. Cut the 3/16" [4.8mm] throttle guide tube
approximately one inch longer than required (for trimming
later). Roughen the tube with medium-grit sandpaper so
glue will adhere, then install the tube through the back
plate mount and the fi rewall. Glue the front of the guide
tube into the back of the fi rewall.

4. Mount the throttle servo to the servo tray. Cut the
guide tube to the correct length, then install the throttle
pushrod using a clevis and a silicone retainer on the
carburetor arm and a screw-lock connector with a metal
one-way
star
retainer on the servo arm. Glue the guide
tube to the side of the fuselage and glue the laser-cut 1/8"
[3.2mm]
guide tube holder
into position.
❏
5. Use the radio to set up your throttle linkage and lock
the pushrod to the screw-lock connector with the 4-40 set
screw and threadlocker.

6. Mount the muffl er to the engine.
Install the Fuel Tank
❏
1. Prepare the fuel tank as shown—it would be a good
idea to mark the location of the fueling line (“F”) and the
vent/pressure line (“V”) on the outside of the tank so you
don’t forget when connecting the fuel tubing later.
❏
2. Insert the stopper into the tank and tighten the screw
to expand the stopper sealing the tank.
❏
3. Use tape to wrap the sides and bottom of the tank in
a sheet of 2-1/2" x 5" [60 x 130mm] 1/4" [6.5mm] RC foam.
❏
4. Install the fuel tank and hold it into position with the
1/8" [3.2mm] lite-ply
fuel tank plate
and another piece of
1/4" [6.5mm] RC foam.
❏
5. Guide the pressure/vent line and the pickup fuel
lines through the holes in the side of the fuselage and
connect them to the fuel tank. Connect the pickup tube
to the carburetor and the pressure/vent line to the muffl er.
