e) Finish the rudder installation by gluing the CA Hinges in
place with Thin CA, using the same techniques you did for the
aileron hinges back in Step 2.
f) After all the glue is dry, adjust the wheel collar to sit snug
against the bottom of the nylon tailwheel bearing. The purpose
of the wheel collar is to keep any loads from the tailwheel from
putting stress on the rudder.
❑
18) Hinge the elevator to the stabilizer, using the same tech-
niques you did for the ailerons back in Step 2 of this manual. Let
the hinges dry before flexing them.
❑
19) Look closely and you will find three holes pre-drilled near
the bottom of the rudder for mounting a nylon control horn. Install
the control horn on the left side of the rudder, with the retaining
plate on the right, using three M2 x 14mm Screws.
❑
20) There are three holes pre-drilled in the elevator for mounting
a nylon control horn. Screw the control horn in position on the
bottom of the elevator, with the retaining plate on the top, using
three M2 x 14mm Screws.
ELEVATOR & RUDDER CONTROLS
For this section you will need:
(1) Fuselage Assembly
(2) 35.5" long Wire Pushrods with M2 Hex Nut
(2) Metal RC Clevis
(2) small pieces of Fuel Tubing
(2) Pushrod Snap Keepers
(1) Radio Receiver (not furnished)
(2) Servos with Mounting Screws (not furnished)
❑
21) Install the rudder and elevator servos inside the fuselage in
the built-in plywood radio mounting tray. Note that the rudder
servo goes on the left side of the airplane, and the elevator servo
goes on the right side. (The servo opening in the front right side
of the tray is for the throttle servo in a glow installation.) Be sure
to drill pilot holes through the plywood tray for the mounting servo
mounting screws.
❑
22) Mount your receiver in a place of your choosing. If using a
glow engine it is recommended that you wrap the receiver in foam
rubber to protect it from vibrations.
❑
23) If you are using a receiver battery pack (some electric pow-
ered setups don't), mount your on/off switch in the fuselage side.
Note that there are precut holes in the fuselage sides, underneath
the covering material, for either a standard size switch or a super
switch with built-in charging plug. Cut away the covering over the
hole that fits your switch and mount using the screw supplied with
your switch.
❑
24) Assemble and install the rudder pushrod.
a) First slide a small piece of Fuel Tubing onto the small end
of the Metal R/C Clevis. Next screw the Hex Nut that is on the
Pushrod Wire all the way up to the end of the threads. Then screw
the metal clevis halfway onto the threads.
b) Locate the pre-cut pushrod exit hole for the rudder on the
left side of the fuselage alongside the fin. Slide the plain d end of
the pushrod wire into the exit hole and inside the pushrod sleeve
built into the fuselage. Slide it in until you can clip the clevis into
the outer hole of the control horn. Lock the rudder in neutral po-
sition with tape, or with two small scrap balsa wood sticks or dow-
els held together with small rubber bands (as shown here).
c) Inside the fuselage, hold the pushrod wire over the rudder
servo output arm and mark the wire where it crosses over the
outer hole in the arm. Make sure the servo is in neutral position.
