The RadioMaster R84 V2 is a lightweight 4-channel PWM receiver compatible with FrSky D8, D16, and Futaba SFHSS protocols via a multi-protocol radio. Designed for smaller aircraft and gliders, it offers a solid control range of over 1km along with fail-safe and RSSI output. At just 22×13×5mm and 2.2g, it’s ideal for compact builds where only a few channels are needed. Requires an external multi-protocol module for binding—does not work with 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.
