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 fuse. Let the CA cure without accelerator.
4. Connect the cowl ring onto the fuse. Slide the cowl over
the cowl ring and onto the fuse. Confi rm that the spinner
backplate properly fi ts 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 fuse so that the colors line up with the covering
on the fuse. The spinner backplate should be centered
over the front cowl opening, and the backplate should be
approximately 3/32" [2.4mm] beyond the front of the cowl.
When satisfi ed, 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. If you do not
have an applicator tip long enough, use a stick to apply a dot
of epoxy to each of the four cowl ring corners.
5. Carefully remove the cowl (and cowl ring) from the fuse
and apply a fi llet of medium or thick CA glue along the front
of the cowl ring where it touches the cowl.
6. Cut a cooling hole out of the underside of the cowl
as shown.
7. Reattach the cowl to the fuse. Install the propeller, prop
washer, and prop nut onto the prop shaft. Install the spinner
cone using the included spinner screws.
8. If you plan to install the instrument panel decal, do so
now. Finish up the assembly by taping the canopy in position.
Clear tape works well for this.
