RadioMaster RP4TD ExpressLRS Receiver, 2.4GHz, True Diversity

In a compact body lies uncompromising stability. The RadioMaster RP4TD is built for pilots demanding the highest link reliability. Dual Semtech SX1281 RF chips, working in True Diversity mode, provide robust performance in interference-heavy or long-range scenarios.

The inclusion of dual TCXO (temperature-compensated oscillators) ensures rock-solid frequency stability, regardless of environmental conditions. Paired with a powerful ESP32 MCU and integrated Wi-Fi, this receiver offers effortless firmware updates and setup directly via WebUI.

Its smart design is sleek, ultralight, and well-cooled, weighing only 1.4 g (without antennas) with compact dimensions of 23.7×16.3×4 mm, making it ideal for any FPV build. The included 65 mm T-antennas guarantee reliable reception at extreme speeds.

A perfect fusion of engineering and performance, the RP4TD is the go-to solution when you need total control, ultra-low latency, and bulletproof signal stability.
