back of the canopy compartment as shown in the photo. This
is the Canopy Aligner. Lift the aligner so that it is slightly
above the sides. Apply a small drop of thick CA to the middle
of the aligner and carefully slide the canopy into place. Push
down on the canopy to force the aligner against the canopy
base (with the canopy aligned with the fuselage sides) and
hold it until the glue has cured (a couple of minutes). Care-
fully remove the canopy and securely glue the aligner to the
canopy base with more CA. A drop of thin CA on each end
of the aligner will harden it and make it last longer.

D 14. Install the canopy again and check to make sure the

nose and the fuselage sides blend smoothly into the canopy.
Use your sanding block with medium or fine grit sandpaper to
smooth out any high spots.

D 11. Temporarily mount the wing in place on the fuse-

lage. VERY CAREFULLY trim the back of the canopy
along the scribe lines, A LITTLE AT A TIME, to fit over the
wing. The scribe lines are just a reference, so take your time
and trial fit the canopy in place often to check your progress.
Once you get the canopy to clear the wing by approximately

1/16", round off the back part with sandpaper to make it look

nice.

INSTALL MOTOR

D 1. Apply one drop of oil to the front and rear motor

bushings. Install the motor by sliding it in from the rear of
former F1. Use the 3mm x 10mm Screws(SCRW056) to
hold it in place. These screws should be firmly tightened but
do not tighten them so tight that they crush the wood.

D 12. Test fit the canopy onto the fuselage. You can sand

the edges of the canopy slightly or you can sand the fuselage
if needed to get it to fit properly.

D 2. Install the prop on the hub using the 6-32 x 5/8"

Socket Head Screw (SCRW037) and the 7/64" Hex Wrench
(WRENCH02). If you are also installing a spinner with a
backplate that goes behind the prop, substitute the 6-32 x

3/4" Socket Head Screw (SCRW057) for the 5/8" screw.
Make sure you tighten the prop screw so it will not come loose
while the prop is spinning.

D 13. Cut
