9. To hinge the ailerons, remove the clear tape that
holds one of the ailerons in place. Pull the aileron off the
wing, revealing four hinges. Center these hinges in their
slots in the AILERON and secure them with THIN CA,
letting it wick into the joint. Glue both sides of the hinge.
10. When the glue has set, re-install the aileron onto the
wing. Hint: if you trim a little bit off each corner of the
hinges, they will insert in the slots easier. While flexing
the aileron one way or the other and while holding the
wing up on its front edge, carefully wick CA into the slot
where the hinge goes into the wing. Do so on both sides
of the hinge. After the glue has set, tug on the aileron at
each hinge location to make sure the hinges are
securely glued in place. Also, make sure the aileron is
free to move up and down.
Note: you can remove any residue from the tape with
alcohol.
Set your wing aside, for now.
FUSELAGE ASSEMBLY
11. Insert the throttle tubing first. It runs along the right
side of the fuselage and goes from the up corner of the
firewall back through the right hole in the first former and
then through second former.
Glue it securely in place with thick CA.
11. Same way to the nose gear tubing. You will have to
use hobby knife to cut away the covering then insert the
tube through the first former and second former.
Glue the tube in place with thick CA.
INSTALL THE MAIN GEAR
13.Locate the main landing gear channel in the bottom
of the fuselage. Use a sharp hobby knife to remove any
covering from the slot. You might lightly coat the
exposed wood in the landing gear slot with 5-minute
epoxy to prevent the wood from becoming fuel soaked.
14.Position the two metal landing gear straps across the
landing gear strut. Using a felt tipped pen, mark the
location for the four landing gear mounting strap holes.
Drill the four mounting holes as marked with 3/32'' drill
bit. Secure the mounting strap by four 3X10 screws.
15. Install the wheels onto the main gear using the
supplied wheel collars and 3X5mm screw. Make sure
the wheel rotates freely.
INSTALL THE ENGINE
16.Attach the engine mount plate, both mounting beams
and the nose gear bearing to the fire wall using the 6-32
X18mm screws provided. Make sure the mounting beam
“webs” are near the outside of the mount. It is not
necessary to fully tighten the four engine mount screws
at this time. Also temporarily install the nose gear, using
the steering arm to secure it. A special collar and
Phillips head set screws inserts in the steering arm,
which secures it to the nose gear. The set screw should
contact the “flat” that is ground into the nose gear. Note
the orientation of the coil on the nose gear. The nose
wheel is secured with two wheel collars and phillips
head set screws.
17.Set the engine on the mount and adjust the beams, if
necessary, so that they are almost touching both sides
of the engine crankcase and are centered in relation to
the engine mount back plate. Now position the engine
so that the front of the thrust washer is approximately 4''
from the fire wall. Note: you will probably have to trim
away the fuselage side for needle valve clearance.
18.Remove the engine and drill a 3/32'' hole at each of
the four marks you just made. “Brake-in” the mounting
holes by inserting a 3X15mm sheet metal screw into
each hole without the engine in place. A drop of oil in
each hole may help the screws thread in easier.
19. Using either Z-bend pliers or a regular pair of pliers,
make a “Z” bend in one end of one .050'' piece of wire.
Slide it into the throttle linkage tube.
Hook the “Z” bend onto your engine's throttle arm and
move the engine into position. You may have to bend
some jogs in the wire to prevent binding of the linkage.
Screw the engine in place on the mount.
Trim the fuselage side as needed for muffler clearance.
Coat any exposed wood with epoxy or CA. Install the
muffler.
20.In a similar fashion, make a “Z” bend in the remaining
piece of .050'' music wire for the nose gear steering arm.
You will need to remove the nose gear so the steering
arm is loose and the “Z” bend can engage the outer hole
of the arm. Slide the music wire into the outer tube and
re-install the nose gear. Make sure the 3X5mm set
screw firmly tightens on the “flat” that is ground on the
nose gear. Rotate the nose wheel back and forth a few
times to make sure it rotates freely without binding. You
may need to bend the pushrod wire slightly to eliminate
any binding in the pushrod. If the alignment between the
nose gear bearing and the engine mount seems to be
causing some binding, loosen the mounting screws and
