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 70mm back from the lead-
ing edge of the wing, measured at the wing
root.
2) If the nose of the plane falls, the plane is
nose heavy. To correct this first move the bat-
tery 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 sides
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
onto the firewall or use a brass heavy hub spin-
ner hub.
When balanced correctly, the airplane should
sit level or slightly nose down when you lift it
up with your fingers.
