FINAL ASSEMBLY
❏
1. Prepare the inside of the cowl by lightly scuffing it with 220-
grit sandpaper. When satisfied, clean the inside with alcohol.
❏
2. Glue the three plywood magnet back pieces to the
cowl ring. Glue a magnet into each of the three holes in the
cowl ring by coating the insides of the holes with medium
CA. A light skin coating of thin CA over the magnets that
overlaps onto the cowl ring will help secure the magnets in
place. Let the CA glue cure without accelerator.
❏
3. Glue three magnets into the holes in the fuselage as
shown. Be sure that the magnets are glued with the
correct polarity facing out! The magnets in the fuselage
must be attracted to the magnets in the cowl ring. As
you did with the cowl ring, apply a light skin coating of thin
CA over the magnets after they have been glued into the
fuselage. Let the CA cure without accelerator.
❏
4. Magnetically attach the cowl ring onto the fuselage.
Slide the cowl over the cowl ring and onto the fuselage.
Confirm that the spinner backplate properly fits your motor
shaft. If not, ream or drill it to the correct diameter.
Temporarily install the spinner backplate onto the prop shaft.
Adjust the position of the cowl on the fuselage so that the
colors line up with the stripes on the fuselage. The spinner
backplate should be centered in the front cowl opening, and
the backplate should be approximately 3/32" [2.4mm]
beyond the front of the cowl. When satisfied, tack glue the
cowl to the cowl ring in three or four spots by reaching
through the front opening in the cowl. A CA applicator tip is
very useful in this step.
❏
5. Remove the cowl (and cowl ring) from the fuselage and
apply a fillet of medium or thick CA glue along the front of
the cowl ring where it touches the cowl.
