8. Hold the carburetor intake piece in place on the
fuse and trace around it with a felt-tip pen. Remove the
covering inside the lines and glue it in place.
❏
9. Install the spinner backplate, propeller and
prop washer onto the crankshaft. Two spinner nuts
are included in the spinner hardware bag. The silver
nut is intended for 2-stroke engines. The black nut is
intended for 4-stroke engines and matches the jam
nut size of O.S. 4-stroke engines. If you are installing
a 4-stroke engine, be sure to fi rst tighten the large
nut included with the engine, then install the 4-stroke
spinner nut.
❏
10. Fit the spinner cone onto the backplate and
center the prop blades in the cutouts. Two spinner
bolts are included in the hardware bag. If you have
installed an O.S. 4-stroke engine, install the shorter
of the two bolts into the spinner cone and thoroughly
tighten it. The longer bolt is intended for engines with
shorter crankshafts.
INSTALL THE COCKPIT KIT AND CANOPY

1. Begin by gluing the cockpit fl oor in position. Be
sure that the fl oor is centered in the cockpit to allow
room for the cockpit side panels. We used hot glue
because it hardens quickly and it can be applied in
thick beads. If you choose to use epoxy or CA, you
will need to make some balsa spacers to fi ll the gap
between the cockpit fl oor and the fuselage.

2. Install the cockpit side panels in the same
manner.

3. Glue the instrument panel and headrest in
position.
