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
128MM
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
128mm
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)
AT THE FUSELAGE. BALANCE A PLANE UPSIDE
DOWN WITH THE FUEL TANK EMPTY.
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.

After you have balanced a plane on the C.G.
You should laterally balance it. Doing this will
help the airplane track straighter.
1. Turn the airplane upside down. Attach one loop
of heavy string to the engine crankshaft and
one to the tail wheel wire. With the wings level,
carefully lift the airplane by the string. This may
require two people to make it easier.
2. If one side of the wing fall, that side is heavier
than the opposite. Add small amounts of lead
weight to the bottom side of the lighter wing
half's wing tip. Follow this procedure until the
wing stays level when you lift the airplane.
