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 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:
High Rate
ELEVATOR 1" [25mm] up
1" [25mm] down
RUDDER 1-1/2" [38mm] right
1-1/2" [38mm] left
AILERONS
Bottom Wing 1" [25mm] up
1" [25mm] down
Top Wing 1-1/4" [32mm] up
1-1/2" [38mm] down 7/8" [22mm] down
NOTE: The aileron throws shown for the top wing
represents the differential created by using the aileron
connecting rod. If you are using four servos instead of two
you do not necessarily need to create the differential in
movement shown here. The control throws up and down
can be the same. Use the greater of the two throws when
setting up the servos on the top wing.
IMPORTANT: The Stearman 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 Stearman 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."
