V-Tail Differential (Air And Sail Types Only); Throttle Cut; Throttle Curve - Spektrum DX9 Instruction Manual

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.

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.

You can use the Throttle Curve menu option to optimize the
throttle response. A maximum of 7 points are available on the
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
