Hi gang! It has been quite a while since I dropped in, been really occupied with trivial and unimportant things like FPV flight!
FPV?
FPV?
First Person Viewer. Or Frilly Pants Variety. Whatever floats your boat.
FPV is as Paul stated First Person View or more aptly Flight Point of View aka an onboard camera with live video stream to the ground. A lot of folks are using Arduino chipsets in their autopilots and OSD/telemetry links.
