inverted mounted engines you will need to open up the bottom of
the cowl as shown in the picture to provide cylinder clearance and
cooling air for the engine. Use the provided template above to
mark out the area to be removed.

19) Slide the cowl over the mounted engine until the prop drive

washer protrudes through the spinner fairing hole at the front. We
used a 1/16" clearance measurement for the distance between the
back of the spinner backplate and the very front of the cowl. To do
this, tack glue four scrap pieces of 1/16" balsa onto the rear of the
spinner backplate. Mount the spinner backplate onto the engine
and hold it in place by lightly bolting a prop on top of it. Slide the
cowl up to the spacers on the back of the spinner backplate,
center the spinner fairing to the back of the spinner and tape in
place. Now line up the color part lines at the back of the cowl with
the same lines on the fuselage and tape the cowl to the fuselage
in this position. Using the six holes, (3 on each side of the cowl),
as guides, drill six 1/16" dia. pilot holes for the cowl mounting
screws. Drill each hole about 1/4" deep. Remove the cowl from
the fuselage. Apply a couple of small drops of thin CA into these
holes to harden them.

TIPS ON CUTTING HOLES IN FIBERGLASS: Always wear
safety glasses and a mask of some kind to avoid inhaling any
fiberglass dust. Use a fine point marker to draw an exact
outline of the area you want to cut out. Then use a Dremel

®

Tool with a parting wheel to remove the material just inside the
lines you have drawn, then switch to a drum-sanding tool to
neatly finish the cutout.

Work slowly and carefully when

removing the material from the cowl. Check your progress
often and make sure you are not removing too much material.
Finally, use #220 sandpaper by hand to clean up and smooth
any rough or jagged edges. Make sure all edges are free of
any loose glass fibers. Be careful not to sand the paint on the
outside of the cowl. Remove all fiberglass dust from the cowl
with a tack rag or with alcohol on a clean cloth.
