D 4. Trial fit the fin in place on top of the stab. Trim it if
neccessary to get a close fit. Glue the fin in place on top of the
stab using either thick CA or epoxy. Check to make sure it is
pointing straight at the nose and is vertical (90 degrees) to the
stab.
sandpaper to taper three sides on each end of both pushrods.
The taper should start about 1 -1/2" from the end. (One of the
sides with the 5/64" holes should remain flat).
ASSEMBLE PUSHRODS
You'll need the following parts:
SPECF09 1/4" Square Balsa Pushrod •
WIRES 10 36" W ire (Threaded both ends)
NYLON03 Nylon Control Horns
D 1. Tack glue the Nylon Control Horns (NYLON03) in
place on the rudder and elevator with a drop of thin CA. Use
the plans as a reference for positioning the horns (Rudder horn
on the left, elevator horn on the bottom). Drill two 3/32"
holes through the control surfaces using the control horns as
guides. Mount the horns with the 2-56 x 3/8" Screws
(SCRW001) and the Nylon Nutplates which were attached to
the horns.
D 2. Cut 5-1/4" off both threaded ends of the 36" Wire
(WIRES 10) and then cut two pieces 12" long from the re-
maining piece of wire. Bend them as shown on the plans
except without the Z-bends. The Z-bends are not bent until
later. Refer to the fuselage "TOP" and "SIDE" views for the
proper bending of the pushrod wires. Wipe off each wire
using a paper towel dampened with rubbing alcohol to re-
move any oil.
D 3. Cut the pushrods from the 1/4" x 11-7/8" Square
Balsa Sticks (SPECF09). The elevator pushrod should be 11-
1/8" long and the rudder pushrod should be 8-3/4" long.
D 6. Insert one threaded piece of wire into each pushrod.
Insert the 12" pieces of wire into the other end of each
pushrod. Tack glue the wires in place with a couple drops of
CA. Firmly wrap the end of the pushrod with strong thread
and apply thick CA to hold everything in place as shown on
the plans and in the photo.
INSTALL RADIO GEAR
D 1. Read and follow the instructions that came with your
radio to install or charge the transmitter and receiver batteries
and gel the servos ready for mounting. Plug the servos and the
battery pack into the receiver and turn on the transmitter
first and then the receiver. Adjust the trim levers to their
neutral positions and allow the servos to return to their neutral
positions.
D 4. Drill a 5/64" hole 2-1/4" in from both ends of each
pushrod.
D 5. Use either a hobby knife, razor plane or coarse
D 2. Slide one of the 1/4" x 3/8" Basswood Servo Rails
(SPRTF11) into its slot in the rear of the fuselage doubler.
Slide it all the way towards the back of the slot and glue it in
place with thick CA. Slide the other servo rail into the slot and
then slide it all the way forward. Do not glue it yet! Position
one of your servos in place and use it to position the front
