Cowlings
IMPORTANT:
* DO NOT CUT THE CENTERS OUT OF THE COWL RINGS
UNTIL YOU HAVE FINISHED SHAPING THE COWL.
* DO NOT GLUE THE CENTERS TOGETHER.
If using magnets to hold the cowl to the nacelle, install
two super-magnets in 1/16” plywood cowl mount C3 as
follows:
a. Glue scrap 1/16” balsa over the front side of C3
to cover the magnet holes.
b. Place a piece of wax paper over the nacelle
firewall.
c. Place a magnet over each of the two magnets
in the firewall.
d. Put one or two drops of epoxy in the magnet
holes on the cowl mount.
e. Place the cowl mount over the magnets so that
the magnets are in the magnet holes.
f. Pin, tape or weight the cowl mount in place until
the epoxy sets.
g. Remove the cowl mount from the firewall.
Glue the rear 1/16 ply mount C3, the five 1/4 balsa
rings C2, and the 1/8 balsa ring C1 together in the order
shown above. Use 1/16 wood dowels (cocktail skewer or
toothpick) to hold parts in alignment. The dowels should not
extend through the 1/8 balsa ring.
Sand the assembled cowl to shape. You can use a
long bolt and nut as a spindle to mount the assembled cowl in
a drill press.
Cut the centers out of the balsa and ply rings. This will
be easier to do if you temporarily remove the 1/16 ply mount
C3.
Glue the radiator shutter (forward 1/16 ply part) inside
the front 1/8 balsa ring.
If you are using outrunner motors, the cowl assembly is
complete. Skip forward to step 10.
Cut the two 1/4” square hardwood motor mount beams
to length, and slip them into their mounting holes on N1 and
N2.
