Digital VTX & Air Units

Digital VTXs and air units transmit HD video for digital FPV. Choose the ecosystem first, because goggles and air units must match: DJI (O4), Walksnail Avatar and HDZero each use their own goggles. DJI and Walksnail offer the sharpest picture, while HDZero has the fixed low latency that racers prefer. Then check power output, the antenna connector (U.FL or MMCX) and whether the camera size fits your frame. For UAVs, the SIYI HM30 and MK32 systems carry HD video to a ground station over long range. We stock Caddx Walksnail, DJI, HDZero, SIYI and BetaFPV. Goggles are in FPV Goggles & Monitors.
