guide, drill the second bulkhead for the control
rod.
51. Slide the “z” bend of the engine control rod into
the hole on the servo arm of your throttle servo.
Temporarily install your engine using the engine
bolts, washers, and nuts, sliding both halves of
the engine control rod through the small hole in
the firewall.
52. Make sure your carburetor and throttle servo are
at low position. Reverse your servo if necessary.
Install an EZ connector (Dubro #121, NOT
INCLUDED) in the hole approximately the same
length of the servo arm. Trim the throttle control
rod to approximate length, then insert through
the hole in the EZ connector. Tighten the
connector enough to test the throw of the servo
and adjust as needed to allow for maximum
throw, but not bind the servo. When satisfied,
trim the control rod to ¼” past the EZ connector.
Install the servo horn screw, but don’t fasten the
EZ connector yet, you may need to pull the
engine out again soon. When everything is fit,
then fuel proof the firewall with polyurethane or
thinned epoxy.
53. Test fit the cowl over the engine to see what
needs to be relieved.
54. Tape a strip of heavy paper on the side of the
fuse as shown. Mark the areas that need to be
cut, then cut out the holes on the paper.
55. Reposition the paper back on the fuse and secure
in place. Do the same for the needle valve on the
top of the fuse.
56. Place the cowl on the front of the fuselage and
secure in place with the screws. Mark all the
holes with a pencil or water soluble marker.
57. Remove the cowl and drill all needed holes. You
may need to use a rotary tool and sanding drum
or a small fine blade saw and sand paper to open
the hole for the engine head.
58. Reinstall your engine and test fit the cowl. Use
the #4 screws and washers to secure the cowl.
Adjust the openings if needed.
59. Install your muffler on the engine and test fit the
cowl again. A “Pitts” style muffler should not
require much adjustment, but a standard aircraft
muffler will require additional openings.
60. Now is when to install the tail servos.
Depending on the engine and mount used, you
may want to install the elevator servo up in the
fuse servo tray. Both installations are shown, but
the materials for the push rod is not included.

the radio gear and even some lead in the nose to
