Monitor every flight in crisp detail on a 4.3-inch 800×480 LCD with 500cd/m² brightness. The high-brightness panel remains clearly visible under direct sunlight—evaluate your framing, confirm your OSD data, and spot obstacles in real time without squinting or shading the screen. The 16:9 aspect ratio matches the output of most FPV cameras and digital systems, delivering a distortion-free preview of the image your goggles or DVR will capture.Lock onto a stable 5.8GHz signal across 40 channels and 5 frequency bands. The built-in receiver covers the full analog FPV spectrum with reliable anti-interference performance. Whether you are setting up at a crowded race event, flying in a remote mountain valley, or operating near urban RF noise, the auto-scan and manual channel selection keep your video feed clean. An RP-SMA male antenna interface ensures a secure, low-loss connection to your existing antennas.Record every pass, crash, and landing with the integrated DVR. Capture footage in VGA, D1, or HD modes using MJPEG AVI format with configurable timer settings. The DVR records directly to a TF card up to 32GB (not included), giving you hours of reviewable flight data. Playback at 30fps on the device itself lets you analyse lines, confirm gate hits, and share moments trackside without needing a laptop.Power through extended sessions with a built-in 1200mAh battery and flexible input options. The internal 3.7V rechargeable cell provides standalone operation. When you need more runtime, the DC 5–23V wide voltage input accepts power from 2S to 6S LiPo packs, and USB power support covers portable power banks and standard chargers. This triple-source flexibility means the monitor adapts to your power availability, not the other way round.Carry a full ground station in one hand with the 159g ultra-slim design. Measuring 146×80×13mm, this monitor slips into any backpack or radio case without adding bulk. A 3.5mm AV input/output with audio toggle connects external receivers, cameras, or secondary displays. The simple English/Chinese menu operates with minimal learning curve. Rated for -10℃ to 65℃ operation, it performs reliably across the cold start of an alpine morning, the humidity of a Dutch afternoon, and the dry heat of a Provençal summer. Compatible with FPV drones, RC cars, and multirotor platforms.
