Spektrum SPM20320 DX3.0 - Manual (Page 16)

30 31
The DX3.0’s electronic Throttle Trim lever, located to the left of the steering wheel, allows the
center position of the servo to be manipulated in either direction to achieve precise centering
of the throttle trigger neutral position. Throttle Endpoint adjustment values (page 24) remain
completely independent from the throttle trim, unless the trim value exceeds the selected
endpoint values. (For example: If the trim value is set at 40 and the endpoint values at 30,
Throttle Trim will override/alter the endpoint value.)
To adjust the Throttle Trim servo position, move the electronic steering trim lever either up
(+) or down (-). As soon as the trim is moved, the THC Throttle Trim screen will appear and
will continue to be displayed unless the trim lever is untouched for a period of two seconds.
To reset the trim value to zero, press the INCREASE and DECREASE keys at the same time
while the “THC” screen is displayed.

Steering Trim
(STC)
The DX3.0 electronic Steering Trim lever, located just above the steering wheel, allows the
center position of the servo to be manipulated in either direction to achieve precise centering
of the steering assembly. Steering Travel Endpoint Adjustment values (page 24) remain
completely independent from the steering trim, unless the trim value exceeds the selected
endpoint values. (For example: If trim value is set at 30 and endpoint values at 15, steering
trim will override/alter the endpoint value.)
To adjust the steering trim servo position, move the electronic Steering Trim lever either to
the left (+) or the right (-). As soon as the trim is moved, the STC Steering Trim screen will
appear and will continue to be displayed unless the trim lever is untouched for a period of
two seconds. To reset the trim value to 0, press the INCREASE and DECREASE keys at the
same time while the “STC” screen is displayed.
Each click will provide 0.3° of trim to the center of the steering servo with a maximum of 12° allowed.
Note: Each click will not always result in a change of the value displayed.
