R304SB Receiver

Description
The Futaba R304SB‑E is a compact 4‑channel 2.4 GHz T‑FHSS telemetry surface receiver designed for use with Futaba surface transmitters that support the T‑FHSS protocol. It features S.Bus2 digital connectivity and built‑in telemetry, and it’s optimized specifically for electric powered (EP) surface models (smaller cars and trucks) rather than gas/nitro vehicles. It supports a wide operating voltage range and provides reliable radio control response with flexible servo compatibility.
