The VTX-F11 is an image transmission transmitter with an output power exceeding 5.5W. It features small size, light weight, low power consumption, low latency, and strong anti-interference capabilities. It incorporates a built-in aluminum heatsink and fan for active cooling to enhance power stability. The transmitter also features temperature protection to prevent overheating during prolonged ground parameter adjustments. It supports IRC protocol OSD parameter tuning is widely used in FPV drone flights, outdoor recreation, racing competitions, and professional aerial photography.
