GET THE MODEL READY TO FLY
Check the Control Directions
❏
1. Turn on the transmitter and receiver and center the trims.
❏
2. With the transmitter and receiver still on, check all the
control surfaces to see if they are centered. If the lengths of
the pushrods need to be adjusted to center the control
surfaces, break the glue bond at the ends of the heat-shrink
tubing and make your adjustments. Be sure to re-glue the
ends of the heat-shrink tubing to the pushrod wires when
you are satisfied.
❏
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.
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
elevator, rudder and ailerons.
These are the recommended control surface throws:
High Rate
ELEVATOR:
3/4" [19mm] up
3/4" [19mm] down
RUDDER:
1" [25mm] right
1" [25mm] left
AILERONS:
1" [25mm] up
1" [25mm] down
IMPORTANT: The FlatOuts Zero 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 FlatOuts Zero 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 receiver, battery
and ESC.
❏
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 2-5/8" [67mm] back from the LE of
the wing at the fuse.
This is where your model should balance for the first flights.
Later, you may wish to experiment by shifting the C.G. up to
1/8" [3mm] forward or 3/8" [9.5mm] 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.
