5. Use 6-minute epoxy to glue the cowl mounting blocks
to former F1 in the locations shown on the plans.
6. Install the prop drive on the geardrive or if using direct
drive, install the prop drive on the motor shaft.
7. Check the fit of the cowl on the fuselage. The aft end
of the cowl should cover the fuselage by only 1/8" to 1/4"
[3.2mm to 6.4mm]. On the full-size Ryan STA the aft end of
the cowl stops at the front of the firewall, leaving a small gap
between the cowl and the fuselage. If you would like, you
can trim your cowl like the full-size one. Install a 1-3/4"
[44.4mm] spinner on the prop drive. Position the cowl
approximately 1/16" [1.6mm] behind the back of the spinner.
8. Use a piece of thin cardboard, taped to the fuselage,
as a template to locate the cowl mounting blocks. Reinstall
the cowl and mark the location of the mounting blocks on
the cowl. Drill 1/16" pilot holes through the cowl and
mounting blocks at each mark. Attach the cowl to the
mounting blocks with #2 x 3/8" sheet metal screws.
Fit the Windscreen & Headrest
1. Trim the windscreen along the cut line.
2. Position the windscreen on the battery hatch as shown
on the plan. The aft edge of the windscreen is approximately
1" [25.4mm] back from the aft former IP. Tape the
windscreen to the battery hatch and mark the outline of the
cockpit sides.
3. Cut out and sand the cockpit following the outline
made in the previous step.
4. Cut the ABS headrest along the cut line and fit it to the
top deck of the fuselage. The headrest fits just behind the aft
edge of the battery hatch. It must clear the hatch so that the
hatch can be removed. Do not glue it in position until after
the fuselage is covered.
