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 reF
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.

testing and operating your radio system.
Step 19.2 Pay particular attention to charging your batter-
ies and range testing your system before and after each
BALANCING THE AIRGRAFT
Step 20.1 The CG for your Fournier RF-4D is located at
2.114 in to 3.114 in (70mm -80mm) back from the leading
edge of the wing when the wing has been attached to the
fuselage as per illustration 30A.
Step 20.2 For the initial flight, the CG should be located at
2.114 (70mm) back from the leading edge of the wing when
the wing has been attached to the fuselage.
Step 20.3 The CG is measured with the engine,radio gear
and all other components installed
Step 20.4 Set up the CG as it will be when you fly it,
Step 20.5 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

flight.
Step 19.3 Check that all
before and after each flight.controls are working correctly
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
Step 21.1 Once you have con-
firmed that the CG is correct, you
should do a thorough review of the
entire model before your first flight.
Check everything twice! Every hook
up, every coupling, everything! Do it
twice!!
Step 21.2 Betore 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 21.3 Once you have completed
your first flight, get in the habit of
checking your model over before and
after each flight! Don't fly if you find
something that is not right!
CONTROL SURFACE THROW SPECIFICATIONS:
The throws are measured at the widest part of the control
surface. Adjust the position of the pushrods at the control
and/or servo horns to control the amount of throw. You may
