NOTE: The decal sheet includes the items you need to
trim your model as shown on the box.
❏
1. Study the photos on the box to determine where to
place the decals.
❏
2. Thoroughly clean your airplane before applying decals.
❏
3. Cut out the individual decal items and apply them in
the locations shown on the plan. HINT: To apply decals
accurately, peel only a small portion of backing from one
end, cut off the backing with a scissors, position the decal
carefully, press down the exposed portion of the decal, peel
off the rest of the backing, then (working from the already
stuck down end) carefully press down the rest of the decal.
❏
4. From Chrome MonoKote or MonoKote Trim Sheet, cut
out a rectangle and apply it to the top of the wing to represent
the top window.
❏
1. Lay the rudder, elevators and ailerons on the plans and
mark on the leading edge of each part the locations of the
hinges, and tailgear. Now use a sharp hobby knife to cut slits
in the covering at the hinge locations. Trial fit the hinges to
make sure you have “found” the slots which you previously
cut. In the same manner, slit the covering at the hinge
locations in the wing, stab and fin TE. Also cut the covering
away from the tailgear slot. Trial fit the elevator to the stab
with the hinges installed. Fit the rudder to the model and
with a pencil, mark the location where the 1/8" wire elevator
joiner interferes with the rudder. Remove the rudder and
with a hobby knife or file, cut a clearance notch for the 1/8"
wire elevator joiner. Reinstall the rudder and check the
notch. The notch should be large enough to allow the rudder
to freely move throughout its entire range of motion.
❏
2. Using coarse sandpaper, roughen the horizontal part
of the tailgear wire, then clean off the sanded portion of the
wire with alcohol or a degreasing solvent. Using a toothpick,
apply a small amount of Vaseline where the tailgear wire
enters the nylon bearing tube (to prevent glue from getting
inside and locking them up).
❏
3. Glue the hinges (and tailgear bearing) into the slots in
the wing, stab and fin TE. NOTE: When gluing in the nylon
tailgear bearing, do not just smear glue on the bearing and
push it into the slot, as most of the glue will be wiped off as
it is being pushed in. You must also work some glue into the
slot. A good way of doing this is to scoop up some epoxy with
a plastic soda straw, then pinch the end of the straw, insert it
into the slot, and squeeze the straw to force glue into the slot.
We recommend 30-minute epoxy for this process. After
pushing in the bearing, wipe away all excess glue with a
tissue dampened with rubbing alcohol.
❏
1. Cut out the Cockpit Floor Pattern on the fuselage plan
and paste it to a scrap piece of 1/8" light plywood (not
included). Cut along the outline to make the cockpit floor. If
you are going to install seats and a pilot, drill 1/16" holes at
the marks provided.
❏
2. Test fit the cockpit floor into the fuselage and sand the
edges if needed to achieve a nice fit. Paint or cover the
cockpit floor to make it look nice.
❏
3. Cut four 1/2" x 3/4" x 1" hardwood mounting blocks
(not included) and glue them to the fuselage sides as shown
in the photo. They should be positioned along the bottom
edge of the upper doubler to allow clearance for the servos.
Mark on the fuse sides, the location of the blocks so you
know where to drill the holes in the next step.
❏
4. Lay the cockpit floor in position and drill 1/16" holes
approximately 1/4" away from the fuse side where each
mounting block is located. Remove the floor and enlarge the
holes in the floor only to 3/32". Use #2 screws to install the floor.
