Great Planes Riot 3D EP ARF - GPMA1570/1571 - Manual (Page 14)

3. Make certain that the control surfaces and motor
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.
Due to the size of the Riot 3D ARF and its control surfaces,
we recommend the use of 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 high rate setting
(not at the 3D rates).
Note: The throws are measured at the widest part of the
elevators, rudder and ailerons.
At this stage the model should be in ready-to-fly condition
with all of the systems in place including the motor, battery,
and the radio system.
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.
Balance the Model (C.G.)
IMPORTANT: The Riot 3D 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 Riot 3D 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.”
These are the recommended control surface throws:
High Rate Low Rate
ELEVATOR: 1/2" [13mm] up 3/8" [9.5mm] up
1/2" [32mm] down 3/8" [9.5mm] down
RUDDER: 1-3/8" [35mm] right 1" [25mm] right
1-3/8" [35mm] left 1" [25mm] left
AILERONS: 5/8" [16mm] up 3/8" [9.5mm] up
