GET THE MODEL READY TO FLY

Check the Control Directions

❏
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.
❏
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.
❏
3. Make certain that the control surfaces and the throttle
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:
High Rate
ELEVATOR: 1/2" [13mm] up
1/2" [13mm] down
RUDDER: 3/4" [19mm] right
3/4" [19mm] left
AILERONS: 3/16" [5mm] up
3/16" [5mm] down
IMPORTANT: The Combat P-40 Warhawk ARF has been
extensively fl own and tested to arrive at the throws at
which it fl ies best. Flying your model at these throws will
provide you with the greatest chance for successful fi rst
fl ights. If, after you have become accustomed to the way
the Combat P-40 Warhawk ARF fl ies, you would like to
change the throws to suit your taste, that is fi ne. However,
too much control throw could make the model diffi cult 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 fl ies, and may
determine whether or not your fi rst fl ight will be successful.
If you value this model and wish to enjoy it for many fl ights,
DO NOT OVERLOOK THIS IMPORTANT PROCEDURE.
A model that is not properly balanced will be unstable and
possibly unfl yable.
At this stage the model should be in ready-to-fl y condition
with all of the systems in place including the engine or
brushless motor, landing gear, and the radio system (and
battery pack if applicable), but with no fuel.
❏
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
fuse. The C.G. is located 1-1/2" [38mm] back from the LE of
the wing where it meets the fuse.
