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

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 125 - 130mm
BACK FROM THE LEADING EDGE OF THE WING, AT
THE FUSELAGE.
Mount the wing to the fuselage. Using a couple of pieces
of masking tape, place them on the top side of the wing
125 - 130mm back from the leading edge, at the fuselage
sides.
Turn the airplane upside down. Place your fingers on the
masking tape and carefully lift the plane.
If the nose of the plane falls, the plane is heavy nose. To
correct this first move the battery pack further back in
the fuselage. If this is not possible or does noi 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
reciever 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
tracl straighter.
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.
If one side of the wing fall, that side is heavier than
the opposite. And small amounts of lead weight to
the bottom side of the lighter wing halfs wing tip.
Follow this procedure until the wing stays level when
you lift the airplane.

We highly recommend setting up a plane using the control
throws listed.
The control throws should be measured at the widest
point of each control surface.
Check to be sure the control surefaces move in the
correct directions.
