P-51 MUSTANG Item code: BH140 . Instruction Manual

Lift the model. If the tail drops when you

lift, the model is “tail heavy” and you must

add weigh* to the nose. If the nose drops, it

is “nose heavy” and you must add weight* to

the tail to balance.

*If possible, first attempt to balance the model

by changing the position of the receiver bat-

tery and receiver. If you are unable to obtain

good balance by doing so, then it will be nec-

essary to add weight to the nose or tail to

achieve the proper balance point.

 With the wing attached to the fuselage, all

parts of the model installed ( ready to fly), and

empty fuel tanks, hold the model at the

marked balance point with the stabilizer level.





 1) We highly recommend setting up a

plane using the control throws listed.







 2) The control throws should be meas-

ured at the widest point of each control sur-

face.







3) Check to be sure the control surfaces

move in the correct directions.

Ailerons : 15 mm up 15 mm down

Flap : 35mm down

Elevator : 20 mm up 20 mm down

Rudder : 30 mm right 30 mm left

We wish you many safe and enjoy-

able flights with your P-51 MUSTANG.





1) Completely charge your transmitter and

receiver batteries before your first day of fly-

ing.







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.





 1) It is critical that your airplane be bal-

anced correctly. Improper balance will cause

your plane to lose control and crash.

THE CENTER OF GRAVITY IS LOCATED

181MM 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 181mm back from

the leading edge, at the fuselage sides.







3. Turn the airplane upside down. Place

your fingers on the masking tape and care-

fully lift the plane .

BALANCING.

Accurately mark the balance point on the top

of the wing on both sides of the fuselage. The

balance point is located 181mm back from

the leading edge. This is the balance point at

which your model should balance for your first

flights. Later, you may wish to experiment by

shifting the balance up to 10mm forward or

back to change the flying characteristics.

Moving the balance forward may improve the

smoothness and arrow- like tracking, but it

may then require more speed for take off

and make it more difficult to slow down for

landing. Moving the balance aft makes the

model more agile with a lighter and snappier

”feel”. In any case, please start at the loca-

tion we recommend .
