GEPRC RAD Whoop 5.8G VTX 400mA Video Transmitter

The GEPRC RAD Whoop 5.8G VTX is a high-efficiency, lightweight analog video transmitter engineered specifically for toothpick configurations and tiny whoop-class FPV drones. Delivering 4 adjustable power stages up to a stable 400mW output ceiling, this VTX balances consistent signal propagation with a thermal design optimized for close to mid-range flight boundaries. It utilizes a regulated 5V power input infrastructure, drawing minimal current so it can be powered directly from a flight controller's 5V rail. Outfitted with an active over-temperature protection loop, it preserves RF core stability by preventing component damage during high-temperature bench configuration. For a unique visual aesthetic, the module features four integrated RGB LEDs that can be fully customized and color-mapped directly through your flight controller's firmware.

Features

Micro Form Factor Optimizations: Engineered explicitly for high-performance tiny whoop and micro toothpick builds, maintaining an ultra-lightweight 2-gram structural footprint.

Onboard Custom RGB Lighting: Factory-equipped with four integrated RGB LEDs, allowing pilots to assign custom color configurations and status tracking animations through the flight controller.

IRC Tramp Telemetry Interface: Seamlessly integrates with standard IRC Tramp protocol fields, allowing pilots to modify video channels, bands, and power steps directly through the Betaflight OSD.

Intelligent Over-Heat Safety: Built-in temperature control monitoring actively safeguards internal processing circuits by throttling RF output stages if thermal safety thresholds are crossed to prevent burning.

Regulated 5V Rail Integration: Low-draw circuit architecture runs entirely on a clean 5V DC supply, pulling only 400mA at maximum output for stress-free integration with onboard BEC lines.

Dual Mounting Layout Footprint: Highly adaptive mechanical design natively accommodates both 25.5mm and 26.5mm mounting configurations with M2 bolt clearance.

Single-Button Interface Logic: Features a simplified physical control button paired with 3 bright LED diagnostic indicators for instantaneous, tool-free field adjustments.
