nZ ADJUST coNTRoL
Adjust the deflection of the control surfaces to match the
specifications on page 12. You can reduce the amount of
throw by doing either or both of the following:
- From the servo end, move the clevis to a hole in the seryo
arm that is closer to the servo output shaft.
SURFACE THROW LIMITS
- From the control horn end, move the control rod/clevis fur-
ther out on the horn (away from the control surface).
Always confirm that the clevis is firmly attached after mak-
ing any adjustment.
FINAL RC SET.UP
Before starting the final set-up of the model, switch on the radio and ensure that all trims are in their neutral positions.
Check that the ailerons, elevator and rudder are centered. lf any adjustments are needed, do these by uncoupling the rel-
evant clevis and turning it clockwise to shorten the linkage or counter - clockwise to lengthen it. Only when each control
surface has been centered mechanically in this way should you begin adjusting the surface movement (or throw)
Now confirm that the control surfaces are moving in the correct direction. Use the servo reversing switches on your trans-
mitter to reverse the direction of a servo if necessary The most popular transmitter mode (with the throttle on the left, with
ailerons and elevator on the right) is shown here.
n4 INSTALLING THE RECEIVER BATTERY
Step 14.1 Consult your radio manual for instructions about
hooking up your receiver battery, receiver and swich har-

Step 14.2Wrap the battery pack securely in foam suitable
for RC equiment and wrap the foam insulated pack in a
plastic bag or cling wrap.

preparation for connecting to your swich harness
Step 14.4 Connect the battery pack connector to your
switch harness according to your radio manual

INSTALLING THE RECEIVER
Step 15.1 Consult your radio manual for instructions about
hooking up your receiver.
Step 15.2 Plan where you are going to put the receiver with
consideration for routing the antenna safely.
Step 15.3 Wrap the receiver securely in foam suitable for
RC equipment and wrap the foam insulated receiver in a

Step 16.1 Consult your radio manual for instructions about
testing and operating your radio system.
Step 16.2 Pay particular attention to charging your batter-
ies and range testing your system before and after each
Step 17.1 The CG for your P51D Mustang is located at
3.112in to 4 in (90mm - 102mm) back from the leading
edge of the wing when the wing has been attached to the
fuselage as per illustration 27A.
Step 17.2 For the initial flight, the CG should be located at
3.112" (90mm) back from the leading edge of the wing when
the wing has been attached to the fuselage.
Step 17.3 The CG is measured with the engine,radio gear
and all other components installed
Step 17.4 Set up the CG as it will be when you fly it.
Step 26.5 lt is very important to have the CG correct, Flying
your model with the CG too far back will likely lead to loss
of control and a crash. lf you discover that after you have

Step 15.4 Generally in the absence of specific instructions
from the radio manufacturer, it is recommended that the
receiver should be placed where it is least likely to have
impact during a crash. Keep the battery pack and other
heavy loose items ahead of the receiver.

Step 16.3 Check that all controls are working correctly
before and after each flight.
assembled your model and installed your radio, motor and
battery that the CG of your model is incorrect you must
bring the CG to the correct location by doing the following
BEFORE FLYING :
- Move the battery pack fore or aft
- Move other components fore or aft
- Change engine to a lighter or heavier model
- Add weight to the nose or tail. lf adding it to the nose,try
to make it useful by going to a heavier duty engine or
adding a spinner with a heavy metal backing plate. As a last
resort, add stick on "dead" weight where appropriate
CONFIRM MECHANICAL INTEGRITY
Step 18.1 Once you have confirmed
that the CG is correct, you should do
a thorough review of the entire model
before your first flight. Check every-
thing twice! Every hook up, every
coupling, everything! Do it twice!!
Step 18.2 Before your first flight,
have an experienced flyer review
your work. Do not fly your model until
it has been checked out by a third
party who knows how to fly and how
to set up a model aircraft. Do not fly
alone. Seek experienced help.
Step 18.3 Once you have completed
your first flight, get in the habit of check-
ing your model over before and after
each flight! Don't fly if you find some-
thing that is not right! 27A.- GG location

CONTROL SURFACE THROW SPECIFICATIONS:
The throws are measured at the widest part of the control also use ATV'S if your radio has them but the mechanical
surface. Adjust the position of the pushrods at the control linkages should still be set so that the ATVS are near 100%
and/or servo horns to control the amount of throw. You may for best servo resolution.
