Stone Deaf...End point is the end of the servo travel each way from neutral... which will determine the "throw" or movement of the control surface, or throttle, and is usually reffered to in percentage of movement,,, 100% being the max. If you need less throw or movement , dial the end point don, to maybe 58% or 70% etc. It is best to get close on the surface movement by setting linkages, then fine tuning with EPA. Alos you can set two different values, see the post above.
