correct polarity facing out! The magnets in the fuselage
must be attracted to the magnets in the cowl ring. Let the CA
cure without accelerator.
o 5. If the hatch is installed, remove it. Connect the cowl
ring onto the fuselage. Slide the cowl over the cowl ring and
onto the fuselage. Confirm that the spinner backplate and
propeller fit your motor shaft. If not, ream or drill them to the
correct diameter. Temporarily install the spinner backplate
and propeller onto the prop shaft. Adjust the position of
the cowl on the fuselage so that the colors line up with the
covering on the fuselage. The spinner backplate should be
centered over the front cowl opening, and the prop should
be approximately 1/8" [3.2 mm] beyond the front edge of the
cowl, all the way around. When satisfied, tack glue (medium
or thick CA recommended) the cowl to the cowl ring in three
or four spots by reaching through the front opening in the
cowl. A CA applicator tip is very useful in this step. If you do
not have an applicator tip long enough, use a stick to apply a
dot of epoxy to each of the four cowl ring corners.
Be careful
not to glue the cowl ring to the firewall! As an additional
precaution, you can use one of the plastic bags that came
in the plane box as a protective liner between the cowl ring
and firewall.
o 6. Carefully remove the cowl (and cowl ring) from the
fuselage and apply a fillet of medium or thick CA glue along
the front of the cowl ring where it touches the cowl.
o 7. Reattach the cowl to the fuselage. Install the propeller,
prop washer, and prop nut onto the prop shaft. Install the
spinner cone using the included spinner screws. Depending
on the size propeller being used, the slots in the spinner cone
may need to be enlarged using a hobby knife or rotary tool.
o 8. If you plan to install the instrument panel decal, do so
now. Finish up the assembly by taping the canopy in position.
Clear tape works well for this.
Apply the decals
1. Use scissors or a sharp hobby knife to cut the decals from
the sheet.
2. Be certain the model is clean and free from oily fingerprints
and dust. Prepare a dishpan or small bucket with a mixture
of liquid dish soap and warm water–about one teaspoon of
soap per gallon of water. Submerse the decal in the soap and
water and peel off the paper backing.
Note: Even though the
decals have a “sticky-back” and are not the water transfer
type, submersing them in soap and water allows accurate
positioning and reduces air bubbles underneath.
3. Position decal on the model where desired. Holding the decal
down, use a paper towel to wipe most of the water away.
4. Use a piece of soft balsa or something similar to squeegee
remaining water from under the decal. Apply the rest of the
decals the same way.
