If exposed to direct sunlight and/or heat, wrinkels can appear. Storing the
model in a cool place will let the wrinkles disappear. Otherwise, remove
wrinkles in covering film with a hair dryer, starting with
low temperature. You can fix the edges by using a hot iron.
Bei Sonneneinstrahlung und/oder Wärme kann die Folie erschlaffen bzw. Falten

* WARNING: When removing any covering from the airframe,
please ensure that you secure the cut edge with CA or similar
cement. This will ensure the covering remain tight.
When you are satisfied with the alignment,
use a pencil to trace around the top and

horizontal stabilizer .
Using a pencil, trace around the vertical
stabilizer where it meets the fuselage.
Remove the vertical stabilizer from the
fuselage.
Using s sharp hobby knife, carefully cut away the
covering below the lines which were drawn in the

Without using glue yet, push the rudder and its hinges into the hinge slots
in the trailing edge of the vertical stabilizer. There should be a minimal
hinge gap and the bottom edge of the rudder should not rub against the
vertical stabilizer.
When satisfied with the alignment, mark the mounting hole position, where
the tail gear torque rod meets the rudder with a pencil.

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 P-51 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”.

THE CENTER OF GRAVITY IS LOCATED 106 - 112mm BACK FROM THE
LEADING EDGE OF THE UPPER WING, AT THE FUSELAGE.
1- Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them
on the top side of the wing (110mm) 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.
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.
20- Balance
21- Control surface
IMPORTANT: Please do not clean your model with strong solvent or pure alcohol, only use kerosene to keep the
colour of your model not fade.
