Radiomaster RP4TD-M ExpressLRS 2.4GHz Mini True Diversity Receiver

RP4TD-M ExpressLRS 2.4GHz Mini True Diversity Receiver

Looking for a lightweight but powerful receiver that doesn't compromise on performance? Enter the RP4TD-M ExpressLRS 2.4GHz Mini True Diversity Receiver . Designed for weight-sensitive builds like racing drones, this mini version of the popular RP4TD weighs just 1 gram but packs the same dual-channel diversity punch, thanks to Gemini technology . Whether you're tearing through the racecourse or taking to the skies for a precision flight, the RP4TD-M delivers top-tier signal sensitivity and signal-to-noise ratio (SNR) performance.

Despite its compact size, the RP4TD-M doesn't skimp on features. With built-in WiFi , you can wirelessly update firmware or tweak settings using the WebUI on your mobile device or PC—no cables, no fuss. Dual 65mm antennas ensure superior durability and performance, and the TCXO (temperature compensated crystal oscillator) provides rock-solid frequency stability, keeping your signals crisp and reliable, even in the harshest conditions.

Compatible with all 2.4GHz ExpressLRS modules , this receiver offers the kind of versatility that makes it a must-have for hobbyists looking to save every gram without sacrificing performance.
