❑ Carefully slide the cowling over the engine and onto the fuselage. The back edge of the cowling (at the top and upper
sides) should overlap the front of the fuselage 1-1/4".
☞
Depending on the size of the engine you've chosen, you may need to cut away a portion of the cowling to clear the
engine's cylinder head. If so, use a Dremel tool with a cutting disc and a sanding drum to make the cutout. Work slowly,
checking the fit often so you don't remove too much of the cowling or damage it.
❑ With the cowling temporarily in place, slide a propeller onto the engine's crankshaft and secure it into place.
❑ Line up the front of the cowling using the crankshaft and
propeller as your guide. When aligned properly, the front
edge of the cowling should be about 3/16" behind the back
edge of the propeller at both sides and the top and bottom.
☞
Position the propeller both vertically and horizontally to
check for the proper gap. This will ensure the front of the
cowling is square to the propeller.
❑ When satisfied with the alignment, use pieces of masking tape to hold the cowling securely in place.
Step 3: Mounting the Cowling
❑ Using a ruler and a pencil, carefully measure and mark
the locations of the four cowl mounting screws.
☞
To make it easier to find the center of the mounting
blocks, first remove the cowling and draw a line from the
center of each block onto the fuselage.
❑ Carefully drill a 5/64" pilot hole into the cowling and
through the cowl mounting block at each of the four locations
you marked.
☞
Make sure the cowling is held securely in place so it
doesn't move while you are drilling the pilot holes.
❑ After drilling the pilot holes, remove the cowling and use a 1/8" drill bit to enlarge only the four holes in the cowling.
☞
Enlarging the holes in the cowling will prevent the mounting screws from cracking the fiberglass.
