RushFPV 3.3G 4W VTX Transmitter Module

The RushFPV 3.3 GHz 4W transmitter is engineered for ultra long-range missions, where penetration and reliability are critical. Operating in the 3.3 GHz band, it offers better wall and foliage penetration compared to standard 5.8 GHz systems, while maintaining cleaner signals in noisy RF environments.

With a maximum output power of 4000 mW (4 W) and selectable levels (25 / 200 / 800 / 1500 / 4000 mW), pilots can adapt transmission strength for both efficient training flights and extreme-distance exploration.

Supporting both IRC Tramp and SmartAudio protocols, the VTX allows remote configuration of channels and power through OSD or radio controller. A robust aluminum heatsink and thermal protection system ensure reliable operation under continuous heavy loads.

Its shielded metal housing reduces interference, while SMA antenna connectors guarantee compatibility with a wide range of FPV antennas. Powered via 7–26 V (2–6S LiPo), the RushFPV 3.3 GHz 4W fits seamlessly into mid- to large-sized long-range drone builds.
