FlySpark 1.2G / 1.3G Long-Range FPV VTX Series | 2W, 4.5W & 5.5W Analog Video Transmitter Modules

The FlySpark 1.2G / 1.3G Long-Range FPV VTX Series is designed for FPV drones, long-range UAV platforms, fixed-wing drones, surveillance drones, inspection UAVs, testing platforms and custom drone builds that require stable analog video transmission in the 1.2GHz / 1.3GHz frequency class. This series includes multiple output-power options, allowing users to select the correct VTX based on range requirement, power budget, antenna configuration, mounting space and mission profile.

The series includes three variants: VTX-F3 2W, SK-VTX05 4.5W and VTX-F11 5.5W. All variants support IRC control protocol and OSD parameter adjustment, allowing convenient configuration through supported flight-controller / OSD workflows. These modules support wide DC input power from 7V to 36V and provide DC 5V output, making them suitable for multiple UAV power-system layouts.

The 2W VTX-F3 is a compact 30.5mm mounting option with MMCX antenna connector. The 4.5W SK-VTX05 and 5.5W VTX-F11 are higher-power modules with SMA antenna interface and 20×20mm mounting pattern.
