Throttle Cut
The Throttle Cut menu option enables you to assign a switch position to stop an engine
or motor. Throttle Cut activates regardless of flight mode. When you activate Throttle Cut,
the throttle channel moves to the pre-programmed position (normally off). You may need
to use a negative value to move the throttle channel to the off position.
CAUTION:
Always test the model after making adjustments to make sure
the model responds to controls as desired.
v-Tail Differential (Air and Sail Types only)
The V-Tail Differential screen enables you to increase or decrease
the amount of differential between control surface throws.
Positive
Differential values decrease the amount of “down” travel
without affecting the “up” travel on the opposite control surface.
Negative
Differential values decrease the amount of “up” travel
without affecting the amount of “down” travel on the opposite
control surface.
The V-Tail Differential menu option only appears when
V-Tail A or V-Tail B is active in Aircraft Type.
To adjust the v-Tail Differential
1. Scroll to Switch and press the scroll wheel. Scroll right to
select On (Differential is always on) or assign the differential
to a switch position.
2. Press the scroll wheel a second time to save the selection.
3. Scroll to Diff: and press the scroll wheel once to change
the value.
4. Press the scroll wheel again to save the selection.
Throttle Curve
You can use the Throttle Curve menu option to optimize
the throttle response. A maximum of 7 points are available
on the throttle curve.
To add points to a Throttle Curve:
1. Move the throttle stick to the position where you wish
to add the new point.
2. Scroll to Add Pt. and press the scroll wheel to add the point.
To remove points from a Throttle Curve:
1. Move the Throttle stick until the cursor is near the point
you wish to remove.
2. Scroll to Remove Pt. and press the scroll wheel once to
remove the point.
If you program multiple throttle curves and you wish to edit one
of the curves, that curve must be active in the Throttle Curve
screen before you can make any changes.
