Currently Playing: Unlocking DJI FPV and understanding the Fatshark Dominator / WalkSnail Avatar HD FPV System
Joonas Trussman is a lead developer on the FPV.WTF project that brought us DJI FPV USB video out and the Margerine root exploit that allows new functionality to be added to the DJI FPV system. He takes us through the hardware and software architecture of DJI FPV and gives his opinion on the new Fatshark Dominator HD FPV System.
