Step 8
Mix a small amount of 30-minute epoxy. Apply epoxy to the
tail gear wire and the slot in the fuselage. Position the tail
gear and use two #2 x 1/2-inch sheet metal screws to attach
the tail gear to the fuselage. Allow the epoxy to fully cure
before proceeding.
Hint: Before installing the screws, apply 2–3 drops
of thin CA into each of the holes to harden the
surrounding wood.

Step 1
Inspect the fuel tank to determine the locations of the vent
line inside the tank. Make sure the vent line of the tank is
pointed towards the top left side of the fuel tank. If you need
to, loosen the fuel tank cap and rotate the cap assembly until
the vent is aligned properly.

Step 2
Attach the fuel tank to the fuselage using the two tie wraps.
Make sure the vent line is up and toward the fuselage when
positioning the fuel tank.

Step 3
Attach the engine to the fuselage using four 4-40 x 1-inch
socket head screws, four #4 washers and four 4-40 lock
nuts. Make sure to position the aluminum engine mounting
plates between the nuts and left side of the fuselage or the
nuts will dig into the wood engine mounts and become loose
very quickly.
