The RadioMaster R81 V2 is an ultra-compact 8‑channel SBUS receiver (no PWM), compatible with FrSky D8/D16 and Futaba SFHSS when used with a multi‑protocol radio. It delivers over 1 km of range, RSSI on channel 9, and operates on 4.5–6 V. At just 17×11 mm and 2 g, it’s perfect for tight micro builds needing streamlined digital output. Requires an external multi‑protocol module—does not bind to FrSky internal RF systems
RadioMaster R Series Receivers: There is a choice of 4 receivers to suit different applications. In addition to PWM channels, R86C & R88 both have SBUS connections and support RSSI. All feature dual antennas and are full range (>1km Control distance) with support for setting a failsafe.
Options:
- R81 Receiver – SBUS
- R84 – 4 PWM Channels
- R86 – 6 PWM Channels
- R86C – 6 PWM Channels / SBUS (8CH)
- R88 – 8 PWM Channels / SBUS (8CH)
Frsky transmitter not supported, only for MPM radio.
Selecting protocol:
Once the receiver has been put into bind mode, it will then cycle between the 3 protocol options: D8, D16 (FCC V1) and S-FHSS:
- Three singles flashes = D8 Protocol
- Three double flashes = D16 Protocol
- Three triple flashes = S-FHSS Protocol
Select Bind on your radio when the receiver reaches the matching protocol.
