Caddx Walksnail Ascent GT Pro VTX 4W Digital Video Transmitter

Caddx Walksnail Ascent GT Pro VTX 4W is an uncompromising, premium-grade digital video transmitter engineered specifically for extreme long-range (LR) missions and challenging RF environments. Operating flawlessly within the Walksnail Avatar HD ecosystem, this module delivers crystal-clear high-definition video with minimal latency.

The defining feature of this transmitter is its massive RF output capability, pushing up to 4000mW (4 Watts). This extreme power level allows pilots to punch through dense interference and extend flight boundaries far beyond traditional video transmitters. To effectively manage thermal loads at peak output, the VTX is enclosed in a rugged, CNC-machined aviation-grade aluminum heatsink housing integrated with an active cooling fan. Supporting a wide input voltage range from 7.4V to 26.4V (2S–6S LiPo), it can be wired directly to the main aircraft battery without the need for dedicated voltage regulators (BECs).

The unit features dual antenna connectors (U.FL) for true diversity transmission to maximize signal stability, and supports onboard HD DVR recording to its internal high-speed flash storage.
