The Signal No Wall Can StopStandard VTXs fade when the path gets tough. Low-rise buildings, dense woods, rockyy canyons—these are signal killers. This unit pushes up to a monstrous 4200mW (4.2W) of clean RF power on the 5.8GHz band. That' s not a typoo. It' s raw, FAA-unfriendly, long-range penetration that keeps your video locked when lesser transmitters glitch to static. Selectable four-gear power (200/500/1000/4200mW) lets you dial back to sip power on the bench, or go full-throttle when the flight demands it.Cool Under PressureGenerating 4.2W of RF creates serious heat. Left unchecked, that heat cooks VTXs into thermal shutdown mid-flight. We solved this with a dual-fan active cooling array and a massive dedicated heat sink. But the real genius is the smart temperature detection system: if the core temp ever pushes into dangerous territory, a blue indicator light extinguishes and the VTX automatically downshifts one power level to protect itself. No blackouts. No meltdowns. Just intelligent, aggressive thermal management that keeps your video alive.Wide Voltage, Clean PowerTake power straight from your flight pack. The 7-36V (2S-8S) input range supports everything from tiny 3-inch cinewhoops to massive X-Class beasts. A clean 5V/200mA output rail is built in, ready to power your FPV camera directly—no separate BEC, no extra wiring, no added weight. Keep your build tight and your installation simple.Tune It Your WayForget struggling with a single physical button buried inside a framee. This VTX supports full SmartAudio protocol—wirelessly configure channels, bands, and power levels directly through your Betaflight OSD or FC UART. Prefer the old-school method? The onboard button still gives you direct access to all 48 channels across 6 frequency bands (A/B/C/D/E/R) for manual setup.Features- EXTREME 4.2W PENETRATION: Four selectable power levels—200mW / 500mW / 1000mW / 4200mW. Navigate concrete jungles, dense forests, and deep canyons without breakup.- DUAL-FAN ACTIVE COOLING: Twin integrated cooling fans paired with a large aluminum heat sink rapidly evacuate heat, preventing thermal throttling on the bench and in-flight.- INTELLIGENT OVERHEAT PROTECTION: Built-in temperature sensor with visual LED indicator. Blue light extinguishes and power auto-downshifts one level when temperatures exceed safe limits—no sudden blackouts.- WIDE 7-36V INPUT: Direct connection to 2S-8S lithium packs. No external BEC or voltage regulator required for the VTX itself.- 5V/200MA CAMERA OUTPUT: Integrated clean power rail to directly supply your FPV camera. Eliminates the need for a separate voltage step-down.- SMART AUDIO + BUTTON CONTROL: Fully compatible with SmartAudio for remote channel/power configuration via FC OSD. Physical button backup for direct manual control.- 48 CHANNELS, 6 BANDS: Supports standard A, B, C, D, E, and R bands. Full coverage from 5362MHz to 5945MHz. Find a clear frequency in any environment.
