3. To secure the battery in the fuselage, glue hook and
loop material to the top of the battery tray and the face of the
motor batteries.

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
electronic speed control 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.
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.
IMPORTANT: The Ryan STA EP 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 Ryan STA EP 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.”
These are the recommended control surface throws:
High Rate Low Rate
ELEVATOR: 3/8" [9.5mm] up 1/4" [6.4mm] up
3/8" [9.5mm] down 1/4" [6.4mm] down
RUDDER: 1" [25.4mm] right 3/4" [19mm] right
1" [25.4mm] left 3/4" [19mm] left
AILERONS: 1/2" [12.7mm] up 3/8" [9.5mm] up
1/2" [12.7mm] down 3/8" [9.5mm] down
