Futaba FUNR6303SBE 3-Channel S.BUS Receiver (FASST, HV) for Park Flyers and Indoor Models  [FUNR6303SBE]

Product summary and suggested placement

The Futaba FUNR6303SBE is a small 2.4GHz receiver ideal for park flyers and indoor aircraft. It offers S.BUS output alongside the FASST protocol for seamless connection to Futaba transmitters and S.BUS-equipped flight controllers. The HV marking reflects compatibility with high-voltage servos when used with the appropriate power arrangement.

Placement should minimise interference and maximise antenna separation. Keep the two antennas orthogonal and well clear of carbon-fibre panels and main power leads. Use soft mounting materials to reduce vibration transfer, avoid laying antenna leads near ESC wiring, and secure the S.BUS connector to prevent strain.

Key setup steps include correct channel mapping and verifying S.BUS linkage. Set the transmitter channels to match the 3-channel layout, check and program fail-safes per your transmitter instructions, and perform ground tests for servo centring and travel. For indoor use, reduce endpoint travel and apply gentle rates for safer handling.

The FUNR6303SBE is a compact S.BUS-ready receiver suited to small electric models; validate antenna layout, S.BUS connections and fail-safe behaviour during bench checks before flight.
