📡 Compact, Reliable, and Built for Electric RC Precision
The Futaba R304SB-E is a 4-channel, telemetry-capable receiver designed specifically for electric-powered RC vehicles. Featuring Futaba’s T-FHSS protocol, this receiver provides lightning-fast response, high signal stability, and full telemetry capability in a compact and efficient package.
Unlike its sibling (the R304SB), the R304SB-E features a built-in internal antenna, providing a sleek, snag-free design ideal for tight chassis layouts and high-performance on-road or off-road builds.
⚙️ About the R304SB-E
Perfectly matched for Futaba’s T-FHSS transmitters (such as the 4PM, 4PM+, and 7PXR), the R304SB-E delivers reliable control and telemetry feedback while maintaining a compact footprint. It’s optimized for electric vehicle (EP) applications, ensuring clear, interference-free operation under racing conditions — without the signal noise that can occur in gas or nitro setups.
This receiver supports S.Bus2 connectivity, allowing advanced telemetry sensors to plug directly into the system, giving drivers access to live voltage, temperature, RPM, and more (depending on transmitter support).
