FUNCTION LIST
Subtrim offsets the entire range of servo travel including the 
center and endpoint positions.
Reverse
Use the Reverse menu to reverse the channel direction. For 
example, if the Steering servo moves Left, reversing the channel 
will move the Steering servo Right.
To reverse a channel direction:
1.  Scroll to Travel and click the scroll wheel. Scroll up or down 
until Reverse appears, then click the scroll wheel again to 
save the selection.
2.  Scroll to the channel you wish to reverse and click the 
scroll wheel.
If you reverse the Throttle channel, a confi rmation screen 
appears. Select YES to reverse the channel. A second screen 
appears, reminding you to bind your transmitter and receiver. 
CAUTION: Always rebind the 
transmitter and receiver after 
reversing the Throttle channel. Failure to 
do so will result in the throttle moving to 
full throttle if failsafe activates.
Always perform a control test after 
making adjustments to confi rm the vehicle 
responds properly.
CAUTION: After adjusting servos, 
always rebind the transmitter and 
receiver to set the failsafe position.
Sub-Trim
Speed
The Speed menu enables you to slow the response time on any 
individual channel.
The Speed is adjustable from 100% to 1%.
To adjust the Speed:
1.  Scroll to the channel you wish to adjust 
and click the scroll wheel.
2.  Scroll Up or Down to adjust the speed 
and click the scroll wheel to save the 
selection.
3.  Select a switch to activate/deactivate the 
function. If Switch ON is selected, the value 
will always be on for that function.
Rates
Rates allow the driver to reduce the travel (0-100%) of the 
Steering, Throttle, or Braking with a trimmer button. The 
Override option allows drivers to select a different rate value 
(0-125%) while holding down the assigned trimmer button. 
This is especially helpful for oval racers that program minimal 
steering throw to desensitize steering during racing, but requires 
maximum steering angle to drive out of a crash or get turned 
around on the track.
To adjust Rate values:
1.  Scroll to Steering and click the scroll 
wheel to select between Steering, 
Throttle or Brake. 
2.  Scroll Up or Down to adjust the Rate value. 
Click the scroll wheel to save the selection.
3.  Set the Switch setting to On to enable 
Rates, select Inh to disable Rates.
4.  Select an Override rate and switch.
5.  Select the OTF (On-The-Fly) trimmer that 
will be used to adjust Rates On-The-Fly.
