You should use Sub-Trims for minor adjustments to servo
linkages, not for major trim adjustments. Using excessive
sub trim percentages can cause a loss in servo travel in
one direction where the servo reaches its travel limit and
stops moving before the control stick is fully deflected.
Use Sub-Trims to fine-tune the alignment of servo arms.
Install servo arms on the servos so that the arms are at
90˚ or perpendicular to the servo case/linkage. As JR
servos feature an odd number of splines on the output
shaft, you can rotate and reinstall the arms to try and
obtain a better position for the servo arm that will require
a lesser amount of sub-trim. Now use the Sub-Trim
function to fine-tune the servo arms that are not quite at
90˚ to the servo.
1. Highlight and select Sub-Trim in the FUNC.LIST to
obtain the Sub-Trim Display.
Note: If a form of CCPM has been selected, channel
naming will vary.
2. Highlight and select the channels where the servo arms
are not quite at the desired position. Once a channel is
selected, rotate the Selector until the servo arm is at
90˚ to the servo case.
Use Travel Adjust to alter how far a servo travels in each
direction. After installing the linkages and attaching them
to the servos, adjust the amount of servo travel in each
direction.
1. Highlight and select TRVL ADJ. in the FUNC.LIST
to obtain the Travel Adjust display.
2. Using the Selector, highlight and select each channel.
Adjust the travel in each direction by rotating the
Selector. You can change the direction of travel by
moving the stick/switch lever back and forth.
Note: If a form of CCPM has been selected, channel
naming will vary.
