JHEMCU VTX30-800 5.8GHz 800mW VTX | IRC Tramp FPV Transmitter | The FPV Project

The JHEMCU VTX30-800 is a lightweight, stack-friendly 5.8GHz analog video transmitter offering 6 switchable power levels up to 800mW. At just 6.8g with a standard 30.5×30.5mm M3 mounting pattern, it drops cleanly into most 5-inch and 7-inch FPV builds — covering everything from indoor low-power flying at 25mW up to 800mW for outdoor range sessions.

Why choose the VTX30-800?

The VTX30-800 sits in the practical mid-range — more power than basic 200mW VTX units, compact enough to stack cleanly, and light enough not to penalise weight-sensitive builds. IRC Tramp support means you can adjust channel and power directly from Betaflight OSD without landing, and the 6-step power range gives you fine-grained control between pit mode and full 800mW output. Pair it with components from our FPV VTX collection for a complete video system.

Key features

6 power levels — PIT to 800mW

PIT, 25mW, 100mW, 200mW, 400mW, and 800mW — more granular power selection than most VTX units in this class, useful for multi-pilot sessions where keeping power low avoids interference, and for pushing range when flying alone.

IRC Tramp — OSD power and channel control

Full IRC Tramp protocol support allows channel, band, and power adjustment directly from Betaflight OSD — no manual button presses needed once wired to a UART TX pad on your flight controller.

Single-button manual control with LED indicators

Short press cycles channels, 2-second hold cycles bands, 5-second hold cycles power levels — clear LED indicators for band, channel, and power make bench setup quick without a connected flight controller.

Lightweight and stack-friendly

At 6.8g and 36x36mm with a 30.5×30.5mm M3 mounting pattern, the VTX30-800 fits cleanly into standard FPV stacks without adapters or custom mounting.

Wide voltage input — 2-6S compatible

Accepts 7-26V input covering 2S through 6S LiPo configurations, with a 5V/1A output for powering an analog FPV camera directly from the VTX.

Build compatibility

30.5×30.5mm M3 mounting pattern — fits standard FPV stacks. MMCX antenna connector — use the included MMCX-to-SMA cable for SMA antennas. Browse our flight controller and AIO range for compatible stack components.

Note: Always connect the antenna before powering on. Never run without an antenna connected — operating without a load can permanently damage the transmitter.
