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
110mm 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 110mm 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 .
4. If the nose of the plane falls, the plane is nose
heavy. To correct this first move the battery
pack further back in the fuselage. If this is not
possible or does not correct it, stick small
amounts of lead weight on the fuselage under
the horizontal stabilizer. If the tail of the plane
falls, the plane is tail heavy. To correct this,
move the battery and receiver forward or if this
is not possible, stick weight into the firewall.
When balanced correctly, the airplane should
sit level or slightly nose down when you lift it
up with your fingers.
