Sub Trim
H-16
Sub Trims are intended for relatively minor adjustments
to servo linkages and not for major trim adjustments to
the helicopter. 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.
