GET THE MODEL READY TO FLY
Check the Control Directions
Warning: Once the motor battery is connected to the ESC,
stay clear of the propeller.
❏
1. Switch on the transmitter and connect the motor battery to
the ESC. Move the throttle stick down to the off position. Switch
on the ESC and center the trims.

2. Make certain that the control surfaces 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.
❏
3. Follow the instructions included with your ESC to arm
the motor. Make sure the propeller is turning in the correct
direction. If not, refer to the ESC instructions to change the
direction of rotation.
Warning! Once the battery is connected to the ESC, stay
clear of the propeller even if the ESC has not been armed.
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:
5/8" [16mm] up
5/8" [16mm] down
RUDDER:
1/2" [13mm] right
1/2" [13mm] left
AILERONS:
5/8" [16mm] up
5/8" [16mm] down
IMPORTANT: The S.E.5a EP 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 S.E.5a EP
ARF 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 motor, landing
gear, motor battery, and the radio system.
❏
1. Use a felt-tip pen or 3mm-wide tape to accurately mark
the C.G. on the bottom of the top wing on both sides of the
fuselage. The C.G. is located 2-1/2" [64mm] back from the
LE of the top wing.
This is where your model should balance for the first
flights. Later, you may wish to experiment by shifting the
C.G. up to 1/4" [6.4mm] forward or 1/4" [6.4mm] back to
change the flying characteristics. Moving the C.G. forward
may improve the smoothness and stability, but the model
may then require more speed for takeoff and make it more
difficult to slow for landing. Moving the C.G. aft makes the
model more maneuverable, but could also cause it to
become too difficult to control. In any case, start at the
recommended balance point and do not at any time
balance the model outside the specified range.
