IMPORTANT: Please do not clean your model with pure alcohol, only use liquid soap with water or use glass cleaner
to clean on surface of your model to keep the colour not fade.
Note: Cut out the stickers and apply them in the
proper area. Do not peel the backing paper off all
at once.
Peel off one corner of the backing and cut off with
scissors.
Arrange sticker on model and when satisfied adhere
the corner without backing.
Carefully peel back the rest of the backing while at
the same time adhering the rest of the sticker.
Try not to make air bubbles, if there are some,
carefully puncture sticker (center of bubble) but not
model surface with the tip
of the knife or sharp pin and squeeze out the air.
At curves stretch sticker and apply a little heat so
that no ceases occur.
Cut off the excess that is produced.

DO NOT try to fly an out-of-balance model !
RUDDER
IMPORTANT: Flying your model at these throws will provide you with the greatest chance for successful first flights.
If,after you have become accustomed to the way the Spitfire flies, you would like to change the throws to suit your taste
that is fine. However, too much control throw could make the model difficult to control, so remember, “more is not always better”.

LATERAL BALANCE:
After you have balanced a plane on the CG, 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 wing level, carefully lift the airplane by the string. This may require two
people to make 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.
THE CENTER OF GRAVITY IS LOCATED 65 - 70mm BACK
FROM THE LEADING EDGE OF THE WING, AT THE
FUSELAGE. BALANCE A PLANE UPSIDE DOWN WITH THE
FUEL TANK EMPTY.
1- Mount the wing to the fuselage. Using a couple of pieces of
masking tape, place them on the top side of the wing (65-70mm)
back from the leading edge, at the fuselage sides.
2- Lift the airplane. Place your fingers on the masking tape and
carefully lift the plane.
3- If the nose of the plane falls, the plane is heavy nose. To correct this, move the
battery pack further back in the fuselage.
If the tail of plane falls, the plane is tail heavy. To correct this, move the battery
forward or if this is not possible, stick weight onto the firewall.
When balanced correctly, the airplane should level or slightly nose down when you
lift it up with your fingers.
