ArduPilot Mega Mission Planner
It’s very difficult to cover everything you get with APM 2.5 in a single video. Please offer requests for detailed reviews of specific topics such as the GPS options, 3DR telemetry radios, minimOSD, or specific Mission Planner functionality such as setting up failsafe, understanding flight modes, etc. I did the best I could to give a feel for what most FPVers would get out of the system in addition to getting an idea of some autopilot functionality.
