Great Planes Piper J-3 Cub 40 Kit - GPMA0160 - Manual (Page 42)

❏
1. You can make a simple step out of scrap pushrod wire.
Drill 5/64" holes just behind the left LG fairing and glue it in
place as shown in the photo.
❏
2. A scale fuel gauge can be made out of two pieces of
dowel and a short piece of pushrod wire (see photo below).
Glue a 1/8" long piece of 1/2" diameter hardwood dowel
between two 1/8" long pieces of 3/8" diameter dowel. Cut or
file some “finger grips” in the 1/2" dowel. Bend a 1" long
piece of scrap pushrod wire 90 degrees approximately 1/8"
from one end. Drill a 5/64" hole in the center of the 3/8"
dowel and glue the bent pushrod wire in place.
❏
3. The windshield bracing can be cut from 1/8" diameter
hardwood dowels (not included). Glue them in place.
❏
4. Install the instrument panel decal. You can also cover
the lightening hole in the top tank floor with black sandpaper
or other material if desired.
❏
5. A scale prop can be made using a regular Top Flite
10 x 6 Power Point Prop. Round off the ends using sandpaper
and use a little bit of dark stain to give the prop a darker color
and to bring out the grain of the wood. Paint the tips black, the
leading edges and tips gold and then apply spots of silver with
a tooth pick to resemble the screws as shown in the photo.
The prop decals are included on the decal sheet. NOTE: This
prop should only be used for “show,” and not for flying.
❏
6. A simple exhaust pipe can be made out of aluminum
tubing. (See box lid.) We used a 1-1/2" long piece of 1/4"
diameter tube with one end sanded to a slant and a 1" long
piece of 3/8" diameter tube. Wrap tape around the unslanted
end of the 1/4" tube until it fits snugly in the 3/8" tube.
Position the tubes as shown in the photo and glue with thin
CA. Drill a 3/8" hole in the bottom of the cowl and glue the
assembly in place with epoxy.
❏
1. Lightly sand a strip approximately 1/8" wide along the
inside of the windshield (around the perimeter). NOTE: To
avoid sanding more than you want, it is helpful to first apply
strips of masking tape on the inside of the windshield, 1/8"
in from the edges.
❏
2. Hold the windshield in place on the fuselage and mark
on the fuse around the outside edge of the windshield with a
fine tip permanent marker. Remove the windshield and use
a T-Pin to poke holes in the covering every 1/8" or so where
the windshield will be glued. Paint the top of the instrument
panel flat black if desired. Use a paper towel soaked with
alcohol to remove the marker from the fuselage.
❏
3. Very carefully glue the windshield in place. Use tape to
hold it in place while the glue cures. There are several glues
available (RC-56, etc.) that work well for installing canopies.
Medium CA also works well, but you must take your time and
only apply a drop or two of CA at a time or the glue may “fog”
the windshield. When using CA, tape the windshield in place
and apply the CA to the outside edge. The CA will wick under
the windshield slightly and will bond the windshield to the
covering material. NOTE: Use care to avoid getting CA on
the outside exposed surface of the windshield.
