throttle servo fi ts through the notch in the tray. Now that
you have an understanding of how all of the parts fi t
together, remove the tray and the pushrod tubes.
❏
17. Apply a small amount of epoxy to the roughened
end of each of the two tubes. Re-install the tubes back
into the holes in the front of the fuselage. The tubes
should be fl ush with the fi rewall. Allow the glue to cure.
❏
18. Once the glue holding the tubes has hardened
glue the plywood servo tray in place. Be sure that the
notch is securely glued to the former and that the plastic
throttle tube passes through the notch in the plywood
servo tray. If necessary, refer to the pictures in step 16
as a reference for the installation.
❏
19. Install the servos into the servo tray. Notice the
orientation of the servo arms and be sure your servos
are installed as shown. The choke servo (the servo
closest to the front of the fuselage) should have a short
servo arm installed. The throttle servo should have the
long servo arm installed. Drill a 1/16" [1.6mm] hole
through each of the servo mounting holes. Secure the
servos with the screws that came with your servos.
❏
20. Locate one of the nylon
ball links. Use a hobby knife
and cut the ball link in half.
The lower portion of the ball
link can be discarded.
❏
21. Install a 2-56 x 1"
[25mm] threaded rod into
the nylon ball link you cut as
well as one additional nylon
ball link.
❏
22. Locate the 24" [610mm] inner pushrod tube. Cut
off a 6" and a 10" length of the tube. Screw the two ball
links to the two tubes you just cut.
❏
23. Assemble a 2-56 clevis,
2-56 nut, clevis keeper and
2-56 x 1" threaded rod as
shown. Assemble two of these.
❏
24. Push the throttle arm and choke arm on the
engine forward. Install each of the clevises into the outer
hole in the servo arms and rotate the arms forward to
the position that would approximate the position of the
servo arm when it is pushing forward the throttle and
choke. With the clevises in place, use the clevis as a
reference for cutting the throttle and choke tubes to the
correct length. Mark the tubes where they should be cut
and the cut them to the proper length. Install a clevis
assembly into both the throttle and choke pushrods.
❏
25. Install the remaining plywood servo tray on the
other side of the fuel tank. Glue it in place the same
way you did for the throttle / choke servo tray.
DECISION YOU MUST MAKE
At this point you have to make a decision as to how
you are going to install the ignition switch. A commonly
accepted method is to simply mount the switch near
the front of the fuselage, keeping it close to the engine.
Because the front of the fuselage is fi berglass as well
as the way the fuselage is constructed there is not a
convenient spot to mount the ignition switch. The next
few steps show our method for mounting the switch on
the fi rewall. This will require the use of an additional
servo since the switch will be servo activated. If you
wish to use our method, continue with the construction.
If you would like to mount the switch elsewhere, skip
ahead to step 37.

26. Install a servo into the forward hole in the servo
tray as shown. Drill a 1/16" [1.6mm] hole through each
of the servo mounting holes. Secure the servo with
the mounting screws that came with the servo. When
