RadioMaster RP3 ELRS Nano Receiver – 2.4GHz FPV for Small Drones

Overview

Introducing the RadioMaster RP3 ELRS Nano Receiver, a compact 2.4 GHz ExpressLRS unit designed for FPV micro drones, Whoops, and compact quads. This slim module pairs fast latency with solid reception to keep your flights feeling responsive and smooth.

Why pilots choose RP3 ELRS Nano

Built around a Skyworks SE2431L LNA and a high-efficiency PA, the RP3 Nano aims to boost sensitivity and telemetry robustness without adding bulk. Antenna diversity helps stabilize links as you navigate through variable environments, from tight indoor courses to open outdoor skies.

• Skyworks SE2431L-based LNA enhances receiver sensitivity for clearer control signals.
• Power amplifier up to 250 mW supports improved telemetry performance and link margins.
• Antenna switching with diversity reduces signal dropouts during quick maneuvers.
• Lightweight design at 4.6 g including two antennas eases mounting on small airframes.
• Tailored for ExpressLRS 2.4 GHz setups on Whoops and micro drones.
