5. Slide the cowl over the cowl ring and onto the fuselage.
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 fuselage so that the colors line
up with the stripes on the fuselage. The spinner backplate
should be centered over the front cowl, and the backplate
should be approximately 5/64" [2mm] beyond the front of the
cowl. When satisfi ed, tack glue the cowl to the cowl ring in
the corners with medium CA by reaching through the front
openings in the cowl. A CA applicator tip is very useful in
this step.
Do not allow CA glue to adhere the cowl ring
to the fi rewall!
Apply the CA sparingly in this step, using
accelerator if desired.

6. Carefully remove the cowl (and cowl ring) from the
fuselage and apply a fi llet of medium or thick CA glue along
the
front only
of the cowl ring where it touches the cowl.

7. Use a rotary tool such as a Dremel with a cutoff wheel
installed to open up the cowl for battery installation as
shown. The cutout should be as wide as the battery tray and
2" [51mm] long. Also, open up a cool air inlet for the battery
just below the prop opening in the cowl.

1. Use a hobby knife to cut a small notch at the edge of the
battery hatch opening for the receiver antenna wire. Tape the
receiver antenna to the underside of the fuselage. Be sure
that it does not interfere with the elevators or rudder.
