BALANCING
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
130mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This
location is recommended for initial test flying
and trimming. There is a 5mm margin forward
and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUEL TANK EMPTY.
2. Mount the wing to the fuselage. Using a couple
of pieces of masking tape, place them on the
top side of the wing 130mm back from the
leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your
fingers on the masking tape and carefully lift
the plane.
