Here is a video showing a waypoint flight with the FY41-AP on the skywalker X8 flying wing. It has some basic information of setting it up but if you need more details you can look the the manuals here.
The video also shows one of the cool features of the FY-41AP that lets you change some of the settings via the built in OSD. Which is one of the nice things I like most about the FY-41AP, and that is just how easy it is to setup.
