RadioMaster RP4TD-M ExpressLRS 2.4GHz Mini True Diversity Receiver
Rs. 2,899.00
The RadioMaster RP4TD-M is a mini true-diversity 2.4GHz ExpressLRS receiver. Two SX1281 radios, each with its own 65mm T antenna, give excellent SNR and RSSI, and a built-in TCXO keeps the frequency stable as temperatures change. At just 1g without antennas it suits 3–5 inch freestyle, cinewhoops and long-range quads alike.

- Built-in TCXO for temperature-stable frequency
- Class-leading SNR and RSSI performance
- Optimised PCB for better heat dissipation
- Durable upgraded 65mm T antennas, pre-installed
