The Futaba R304SB is a compact and lightweight T-FHSS 2.4 GHz receiver with integrated telemetry function. The receiver is particularly suitable for indoor use in electric RC cars. As a special feature, the antenna of the receiver is integrated into the housing.

S.BUS2 sensors can be connected via the S.BUS2 connection and up to 32 telemetry data records can be transmitted. The telemetry transmitter integrated in the receiver transmits the telemetry data present at the S.BUS2 connection to the transmitter, which displays, announces or acoustically outputs them in the display.

NOTE: When using 7.4 V LiPo batteries as receiver batteries, the connected servos must also be designed for this voltage. The receiver does not have an internal voltage converter for the servo voltage!
