Care should be taken when switching the Channel number for a port. It is
possible that some channel positions can greatly over-extend the expected
amount of throw and damage the servo, linkage, or surface!
The EPA L and EPA H settings allow you to change the end points for the
high and low positions (each end of the servo's travel). When you have
either EPA L or EPA H selected, and the transmitter is on and the receiver(s)
are connected, then changes to the stick position will automatically select
the proper EPA L or EPA H setting for you. Changing the end point values is
how you can manually match surfaces together.
The Servo setting allows you to set the Servo type to be either Digital or
Analog. The difference is the frame rate passed to the servo. If you are
using a fast frame rate radio (under 20ms), most analog servos will have a
problem processing the fast update (frame) rate, and this can lead to servo
failure, sometimes immediately! To eliminate this problem, set the Servo
type to be Analog. This will double the time between servo updates, and
eliminates the problem completely. If you are using a digital servo on the
selected output port you will want to set the Servo type to be digital so that
the latency is reduced.
