Canopy Mounting.
Do not glue the canopy to the hatch without the
hatch mounted to the fuselage. You can warp it
and it will not fit back on the fuselage.
1. Mount the hatch to the fuselage using the two
4-40 x 1/2” screws.
Put a piece of wax paper between the tur-
tledeck and canopy bulkhead to prevent glue
from getting in the seam.
. Put a bead of canopy glue around the edge of
the canopy on the inside and fit into place.
Make sure canopy is properly positioned and
hold in place with masking tape till glue dries.
Most canopy glues can be cleaned up with water
while still wet. Check the glue instructions
Remove any smudges with a damp cloth.
Final Assembly
1. Attach cowl using locktite on the screws.

2. Trial fit the wing tube into each wing panel.If
very tight try a little wax on the wing tube.
Work it in and out till it frees up.
Fit both wing in place and hold in place with
the 1/4-20 nylon bolts. The bolts are sent full
length, you will probably want to cut them
down to about 3/4” to 1” to make them easier to
install.
3. Install the battery pack according to where you
need the weight to make the CG correct.
With all equipment installed, check the CG.
The C.G. should be 3-3/4” to 4-1/8” behind
the leading edge at the fuselage side.
