D/R & Exponential; Motor Cut; Motor Curve - Spektrum DX20 Instruction Manual

MULTI (MULTIROTOR)
D/R & Exponential
Dual Rates and Exponential are available on the PiT, ROL and YAW
channels.
To adjust the Dual Rate and Exponential:
1. Scroll to the channel and press the scroll wheel once. Scroll
left or right to select the channel you wish to change and
press the scroll wheel again to save the selection.
2. Scroll to Switch and press the scroll wheel to select. Move
the switch you want to assign to D/R.
3. Scroll to dual rate and press the scroll wheel. Scroll left or
right to change the value and press the scroll wheel again
to save the selection.
Exponential affects control response sensitivity around center but
has no affect on overall travel. Positive exponential decreases the
sensitivity around the center of gimbal movement.

Motor Cut

The Motor Cut menu option enables you to assign a switch
position to stop the motor. Motor Cut activates regardless of Flight
Mode.
When you activate Motor Cut, the ALT channel moves to the
pre-programmed position (normally Off).
You may need to use a negative value to move the ALT channel to
the off position.
CAUTION: Always test the model after making
adjustments to make sure the model responds to controls
as desired.

Motor Curve

You can use the Motor Curve menu option to optimize the throttle
response. A maximum of 7 points are available on the throttle
curve.
To add points to a Motor 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 Motor Curve:
1. Move the Motor 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 Motor Curve screen
before you can make any changes.
