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. Adjust if necessary.
Set the Control Throws
Use 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:
3/4" [19mm], 12° up
3/4" [19mm], 12° down
RUDDER:
3-1/2" [89mm], 30° left
3-1/2" [89mm], 30° right
AILERONS:
3/4" [19mm], 15° up
3/4" [19mm], 15° down
LOW RATE
ELEVATOR:
1/2" [13mm], 8° up
1/2" [13mm], 8° down
RUDDER:
2" [51mm], 17° left
2" [51mm], 17° right
AILERONS:
1/2" [13mm], 10° up
1/2" [13mm], 10° down
3D RATE
ELEVATOR:
2-1/2" [64mm], 42° up
2-1/2" [64mm], 42° down
RUDDER:
5" [127mm], 45° left
5" [127mm], 45° right
AILERONS:
1-3/4" [44mm], 40° up
1-3/4" [44mm], 40° down
We also put exponential into the high rates and the 3D rates to
make the control throws less sensitive around neutral. These
can be set up to your own preference and fl ying style. We put
20% to 30% in the high rate and 50% to 60% in the 3D rates.
IMPORTANT: The Edge 540T EP has been extensively
fl own and tested to arrive at the throws at which it fl ies
best. Flying your model at these throws will provide you
with the greatest chance for successful fi rst fl ights. If, after
you have become accustomed to the way the Edge 540T
EP fl ies, you would like to change the throws to suit your
taste, that is fi ne. However, too much control throw could
make the model diffi cult to control, so remember, “more is
not always better.”
