2. Slide the cowl onto the fuselage. Fit the spinner backplate
onto the prop adapter (if you are using the recommended
O.S. motor you will need to enlarge the hole in the backplate
to 5.0mm). Position the cowl so that the front of the cowl is
centered behind the backplate and there is a 5/64" [2 mm]
gap between the cowl and backplate. Use a felt-tip pen to
make marks through the holes in the card stock onto the cowl.
❏
3. Drill 1/16" [1.6mm] holes at your marks through the cowl,
through the wing fairings and through the fuselage sides.
Remove the cowl from the fuselage. Thread a 2.3 x 10mm
washer head screw into each hole in the fuselage and back
it out. Apply a drop of thin CA to each hole and let the glue
harden. Enlarge the holes in the cowl to 3/32" [2.4mm]. Install
the cowl using four 2.3 x 10mm washer head screws.

4. Use CA to glue a
magnet into each plywood
disk. Allow the glue to harden
completely before continuing
to the next step.

5. Magnetically attach the disks from the previous step to
the magnets in the fuselage. Without glue, test fi t the canopy
onto the fuselage by fi tting the forward end underneath the cowl.

6. Apply a thin fi lm of medium or thick CA glue onto the center
of each magnet that is inside the plywood disks.
