D/R & Exponential; Differential (Acro And Sail Types Only); Throttle Cut (Acro And Heli Types Only); Throttle Curve (Acro And Heli Types Only) - Spektrum SPMR8100 Instruction Manual

FUNCTION LIST
 D/R & Exponential
Dual Rates and Exponential are available on the aileron, elevator
and rudder 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 select the switch to activate D/R and
Expo for that channel.
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.
 Differential (ACRO and SAIL Types Only)
The Differential screen enables you to increase or decrease the
amount of differential between aileron 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 Differential menu option only appears when a multi-servo
aileron wing type is active in Aircraft Type.
To adjust the 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 (ACRO and HELI Types Only)
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.
 Throttle Curve (ACRO and HELI Types Only)
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.
SPEKTRUM DX8e • TRANSMITTER INSTRUCTION MANUAL
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.
2. Press the scroll wheel a second time to save the selection.
3. Scroll to the percentage selection and press the scroll wheel
once to change the value.
4. Press the scroll wheel again to save the selection.
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.
