I'm still stumped by AFR!
"End Point" screen sets up the actual mechanical full throw than can be obtained without stalling the servo. You do not have to set end point to MAX but you want to make sure that you do not exceed the mechanical limit of a function so as to not stall a servo. AFR stands for "Adjustable Function Rate" this means you adjust each function to the "ACTUAL" full rate that you would ever want to fly with! You then adjust your dual and triple rates for various manauvers you intend to fly with.
