R304SB-E Futaba 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 capability to send real‑time data back to compatible transmitters. It’s optimized for electric powered surface RC vehicles only and should not be used in gas/nitro cars.
