4. For this step you will find that a helper will be an asset.
Position the cowl onto the fuselage, aligning the paint lines
on the fuselage and the cowl as well as centering the engine
in the opening in the front of the cowl. From the marks you
made on the sides of the fuselage measure forward 2"
[51mm]. Drill through the cowl and the mounting blocks with
a 5/64" [2mm] drill. Install the cowl to the fuselage with five
2.5 x 10mm washer head screws.
❏
5. Make all of the final cuts to the cowl to accommodate
the glow driver, muffler, needle valve, etc.
❏
1. Locate three .074" x 36" [1.9 x 914mm] pushrod wires
threaded on one end. Screw a nylon clevis onto the
threaded end of the wires 20 full turns. Install a silicone
clevis keeper onto the clevises.
❏
2. Slide two of the wires with clevises attached into the
openings closest to the back of the fuselage on both sides
of the fuselage.
❏
3. Connect a nylon control horn onto each of the two
clevises. Position the control horn on the elevators, positioning
it the same way as you did with the ailerons. Mark the location
for the screw holes. Drill through the marks you made with a
1/16" [1.6mm] drill bit, drilling through the elevator. Secure the
control horn to the aileron with two 2-56 x 5/8” [16mm]
machine screws and the nylon mounting plate.
❏
4. Insert the third rod into the remaining opening in the
fuselage. Connect the control horn to the clevis. Mark the
location for the control horn onto the rudder. Drill a 1/16"
[1.6mm] hole on each of the marks drilling through the
plywood plate
but do not drill through the rudder! Install
and then a remove a #2 x 3/8" [9mm] screw into each of the
holes. Apply a couple of drops of thin CA to harden the
threads. Once the glue has hardened mount the control horn
to the rudder with the #2 screws.
❏
5. Install the rudder servo into the servo tray at the
position shown. Mark the location for the servo mounting
screws. Drill a 1/16” [1.6mm] hole through the marks, drilling
through the plywood tray. Insert and then remove one of the
servo mounting screws supplied with your radio into each of
the four holes you have drilled. Apply a couple of drops of
thin CA to each of the holes to harden the threads. After the
glue has hardened permanently mount the servo.
