Sub-trim is an electronic trim that is available for
each of the six channels. Sub-trim is particularly
useful as it allows the mechanical trim levers to be
returned to their neutral positions by adjusting/
changing the servo’s neutral position electronically,
without the need to mechanically adjust the specific
control linkage. This allows the same mechanical
trim lever settings between the four models you can
control with this radio system. Sub-trim can also
allow additional trim travel when mechanical trims
do not provide enough movement.
Note: It is recommended to use as little subtrim as
possible for adjustment. If more that 20–30 points
are required, is it suggested that a mechanical
linkage adjustment be performed.
