harnesses will be required. Mixing at the
transmitter will be required.
When using a six channel radio, a Y-
harness has been included for the aps.
Mixing at the transmitter will be required
to operate the ailerons.
Using a ve channel radio will require
the use of the included Y-harness for
the aps, and an additional Y-harness
(SPMA3058) for the ailerons.

BALANCING
1) It is critical that your airplane be
balanced correctly. Improper balance will
cause your plane to lose control and
crash. THE CENTER OF GRAV-
ITY IS LOCATED 70MM BACK
FROM THE LEADING EDGE OF
THE WING AT THE WING ROOT.
2) Mount the wing to the fuselage. Place a
piece of masking tape on the top of each
wing 88mm back from the leading edge
at the wing root.
3) With the model inverted, place your
ngers on the masking tape and carefully
li the plane. is is the point at which
your model should balance for your rst
ights. Later, you may wish to experi-
ment by shiing the balance up to 70mm
forward or back to change the ying
characteristics. Moving the balance for-
ward may improve the smoothness and
arrow- like tracking, but it may then re-
quire more speed for take o and make it
more dicult to slow down for landing.
Moving the balance a makes the model
more agile with a lighter and snappier
”feel”. In any case, please start at the loca-
tion we recommend.
With the wings attached to the fuselage,
all parts of the model installed ( ready to
y), and empty fuel tanks, hold the model
at the marked balance point with the sta-
bilizer level.
*If possible, rst attempt to balance the
model by changing the position of the re-
ceiver battery and receiver. If you are un-
able to obtain good balance by doing so,
then it will be necessary to add weight to
the nose or tail to achieve the
proper balance point.

2) If all the decals are not precut, please
use scissors or a sharp hobby knife to cut
the decals from the sheet. Please be cer-
tain the model is clean and free from oily
ngerprints and dust. Position decal on
the model where desired, using the pho-
tos on the box and aid in their location.
1) If all the decals are precut and ready to
stick. Please be certain the model is clean
and free from oily ngerprints and dust.
Position decal on the model where de-
sired, using the photos on the box and aid
in their location.

Li the model. If the tail drops when
you li, the model is “tail heavy” and you
must add weight* to the nose. If the nose
drops, it is “nose heavy” and you must
add weight* to the tail to balance.

FLIGHT PREPARATION PREFLIGHT CHECK
Check the operation and direction
of the elevator, rudder, ailerons and
throttle.
A) Plug in your radio system per the
manufacturer’s instructions and turn
everything on.
B) Check the elevator rst. Pull
back on the elevator stick. e eleva-
tor halves should move up. If it they do
not, ip the servo reversing switch on
your transmitter to change the direc-
tion.
C) Check the rudder. Looking from
behind the airplane, move the rudder
stick to the right. e rudder should
move to the right. If it does not, ip
the servo reversing switch on your
transmitter to change the direction.
D) Check the throttle. Moving the
throttle stick forward should open the
carburetor barrel. If it does not, ip the
servo reversing switch on your trans-
mitter to change the direction.
E) From behind the airplane, look
at the aileron on the right wing half.
Move the aileron stick to the right.
e right aileron should move up and
the other aileron should move down.
If it does not, ip the servo reversing
switch on your transmitter to change
the direction.
1) Completely charge your trans-
mitter and receiver batteries before
your rst day of ying.
2) Check every bolt and every glue
joint in the Magic Bird EF1 RACER
40E PNP, 46” to ensure that every-
thing is tight and well bonded.
3) Double check the balance of the
airplane. Do this with the fuel tank
empty.
4) Check the control surfaces. All
should move in the correct direction
and not bind in any way.
5) If your radio transmitter is
equipped with dual rate switches
double check that they are on the low
rate setting for your rst few ights.
6) Check to ensure the control sur-
faces are moving the proper amount
for both low and high rate settings.
7) Check the receiver antenna.
It should be fully extended and not
coiled up inside the fuselage.
We wish you many safe and enjoyable ights
with your Magic Bird EF1 RACER 40E PNP, 46”.
8) Properly balance the propeller.
An out of balance propeller will cause
excessive vibration which could lead
to engine and/or airframe failure.
