FUTABA 8UHPS Instruction Manual page 32

The ATV function is used to set the travel of each servo in both directions. At a
100% setting, the throw of the servo is approximately 40° for channels 1 – 4 and
approximately 55° for channels 5 – 8. Reducing the percentage settings reduces the
total servo throw in that direction. The ATV menus should be set to prevent any
servo binding at extreme travel.

You can use D/R dual rate settings to reduce (or increase) the servo travels by flipping
a switch, or they can be engaged by any stick position. The travel reduction or
increase for the ailerons, elevator, and rudder may be controlled by this menu.
The default locations of the Dual rate switches (factory settings) are as follows:
aileron: Switch D; elevator: Switch A; rudder: Switch B.
You may select your own positions for the switches. You may also program your
system so that the dual rates are automatically activated when you move any stick past
a certain position.
