GET THE MODEL READY TO FLY
CHECK THE CONTROL DIRECTIONS
o 1 . Turn on the transmitter and receiver and center
the trims . If necessary, remove the servo arms from
the servos and reposition them so they are centered .
Reinstall the screws that hold on the servo arms .
o 2 . With the transmitter and receiver still on, check
all the control surfaces to see if they are centered .
If necessary, adjust the clevises on the pushrods to
center the control surfaces .

o 3 . Make certain that the control surfaces and
the carburetor respond in the correct direction as
shown in the diagram . If any of the controls respond
in the wrong direction, use the servo reversing in
the transmitter to reverse the servos connected to
those controls . Be certain the control surfaces have
remained centered . Adjust if necessary .
SET THE CONTROL THROWS
Use a Great Planes AccuThrow (or a ruler) to
accurately measure and set the control throw of each
control surface as indicated in the chart that follows . If
your radio does not have dual rates, we recommend
setting the throws at the
low rate setting .
NOTE: The throws are measured at the widest part
of the elevators, rudder and ailerons .
These are the recommended
control surface throws:

FLAPS
Note: When flaps are deployed you can expect the
airplane to balloon slightly . To minimize this we mixed
1/32" [0 .8mm] down elevator trim when the flaps were
deployed . If you have a flap to elevator mix you may
wish to consider this mix as well .
IMPORTANT: The P-47 ARF has been
extensively flown and tested to arrive at the
throws at which it flies best . 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-47
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 .”
BALANCE THE MODEL (C.G.)
More than any other factor, the C.G. (balance
point) can have the greatest effect on how a model
flies, and may determine whether or not your first
flight will be successful . If you value this model
and wish to enjoy it for many flights,
DO NOT
OVERLOOK THIS IMPORTANT PROCEDURE.
A model that is not properly balanced will be
unstable and possibly unflyable .
At this stage the model should be in ready-to-fly
condition with all of the systems in place including
the engine, landing gear, and the radio system .
o 1 . Use a felt-tip pen or 1/8" [3mm]-wide tape to
accurately mark the C .G . on the top of the wing on
both sides of the fuselage . The C .G . is located 4-1/8"
[105mm] back from the leading edge of the wing
where it meets the fuse .
