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 141MM
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
141mm 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.
BALANCING
LATERAL BALANCE
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.
1) We highly recommend setting up a plane using
the control throws listed.
2) The control throws should be measured at the
widest point of each control surface.
3) Check to be sure the control surfaces move in the
correct directions.

PRE-FLIGHT CHECK
1) Completely charge your transmitter and
receiver batteries before your first day of flying.
2) Check every bolt and every glue joint in your
plane to ensure that everything is tight and well
bonded.
3) Double check the balance of the airplane.
4) Check the control surface.
5) Check the receiver antenna. It should be fully
extended and not coiled up inside the fuselage.
6) Properly balance the propeller.
