Step 2: Installing the Cowling
Remove the cowling and enlarge only the holes in the cowling using a 1/8" drill bit.
Enlarging the holes will prevent the fiberglass from being cracked when you install the wood screws.
To strengthen the holes in the fuselage that the wood screws will thread into, carefully apply a couple of drops of thin
C/A into the holes and let it dry completely before installing the cowling.
At this time you should make the rest of the cutouts in the cowling for your engine. These include cutouts for the high
and low speed needle valves and the muffler assembly.
Slide the cowling into position and realign it. Install and tighten the four M3 x 6 wood screws and four M3 flat washers
to hold the cowling firmly in place.
Step 3: Installing the Spinner Assembly & Engine Accessories
Install the needle valve and muffler assembly onto your engine, then cut to length and install the fuel lines to the
muffler pressure nipple and the carburetor (or remote needle valve).
Install the spinner backplate and the propeller onto your engine and tighten the propeller nut firmly.
Test-fit the spinner cone over the propeller. Depending on the size of the propeller you are using, the spinner cone
may not fit over it. If this is the case, use a modeling knife to very carefully enlarge the two cutouts in the spinner cone.
It is important that the spinner cone not touch any part of the propeller when it is in place.

With the cowling held firmly in place, drill 5/64" diameter
pilot holes into the cowling and through the fuselage for the
four wood screws. Locate two holes on each side of the
cowling, 1/4" in front of the back edge of the cowling. One
hole should be 1/2" up from the bottom, and the second hole
should be 1/2" down from the top.
When satisfied with the fit, slide the spinner cone over
the propeller.
Install and tighten the two wood screws to secure the
spinner cone into place.
