Instruction Manual

Position the canopy so the rear frame on the canopy is
aligned with the rear edge of the cockpit opening. Use
canopy glue to secure the canopy to the canopy hatch.
Use low-tack tape to hold the canopy in position until
the glue fully cures. Wrap the tape completely around
the canopy hatch, as the tape does not stick well to
the covering. We used balsa sticks to hold the lower
edges of the canopy tightly against the canopy hatch.

1)
It is critical that your airplane be balanced
correctly. Improper balance will cause your plane
to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
110 MM
BACK FROM THE LEADING EDGE OF
THE WING.

2)
Mount the wing to the fuselage. Using a
couple of pieces of masking tape, place them on
the top side of the wing
110 mm
back from the
leading edge, at the fuselage sides.

3)
Turn the airplane upside down. Place your
ngers on the masking tape and carefully lift the
plane.
Accurately mark the balance point on the top of the
wing on both sides of the fuselage. The balance
point is located
110 mm
back from the leading
edge. This is the balance point at which your model
should balance for your rst ights. Later, you may
wish to experiment by shifting the balance up to
10mm forward or back to change the ying charac-
teristics. Moving the balance forward may improve
the smoothness and arrow- like tracking, but it may
then require more speed for take off and make
it more dif cult to slow down for landing. Moving
