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\u003c\/p\u003e\n\u003cp\u003eRadioMaster R Series Receivers: There is a choice of 4 receivers to suit different applications. In addition to PWM channels, R86C \u0026amp; R88 both have SBUS connections and support RSSI. All feature dual antennas and are full range (\u0026gt;1km Control distance) with support for setting a failsafe.\u003c\/p\u003e\n\u003cp\u003eOptions:\u003c\/p\u003e\n\u003cp\u003eR81 Receiver – SBUS\u003c\/p\u003e\n\u003cp\u003eR84 – 4 PWM Channels\u003c\/p\u003e\n\u003cp\u003eR86 – 6 PWM Channels\u003c\/p\u003e\n\u003cp\u003eR86C – 6 PWM Channels \/ SBUS (8CH)\u003c\/p\u003e\n\u003cp\u003eR88 – 8 PWM Channels \/ SBUS (8CH)\u003c\/p\u003e\n\u003cp\u003eFrsky transmitter not supported, only for MPM radio.\u003c\/p\u003e\n\u003cp\u003eSelecting protocol:\u003c\/p\u003e\n\u003cp\u003eOnce the receiver has been put into bind mode, it will then cycle between the 3 protocol options: D8, D16 (FCC V1) and S-FHSS:\u003c\/p\u003e\n\u003cp\u003eThree singles flashes = D8 Protocol\u003c\/p\u003e\n\u003cp\u003eThree double flashes = D16 Protocol\u003c\/p\u003e\n\u003cp\u003eThree triple flashes = S-FHSS Protocol\u003c\/p\u003e\n\u003cp\u003eSelect Bind on your radio when the receiver reaches the matching protocol.\u003c\/p\u003e\n\u003cp\u003eAssociated Products\u003c\/p\u003e\n\u003cp\u003eReplacement Antenna for R84 R86 R86C R88 Receiver\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: R81 – D8 Nano Sbus Receiver\u003c\/li\u003e\n\u003cli\u003eChannels: 8\u003c\/li\u003e\n\u003cli\u003eFrequency range: 2400-2483.5Mhz\u003c\/li\u003e\n\u003cli\u003ePower input range: 4.5-6V\u003c\/li\u003e\n\u003cli\u003eSignal format: D8, D16 \u0026amp; SFHSS Compatible\u003c\/li\u003e\n\u003cli\u003eOutput format: SBUS\u003c\/li\u003e\n\u003cli\u003eRSSI: RSSI on Ch9 of Sbus Output\u003c\/li\u003e\n\u003cli\u003eRange: more than 1km\u003c\/li\u003e\n\u003cli\u003eAntenna length: Approximately 6cm\u003c\/li\u003e\n\u003cli\u003eSize: 17x11mm\u003c\/li\u003e\n\u003cli\u003eWeight: 2 grams\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RadioMaster","offers":[{"title":"Default Title","offer_id":58941250044236,"sku":"RX-RMR81V2","price":13.9,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1087\/9952\/5196\/files\/RadioMaster-R81-V2-Receiver.jpg?v=1790286684","url":"https:\/\/dronepart.co.uk\/products\/radiomaster-r81-v2-8ch-frsky-d8-16-futaba-sfhss-compatible","provider":"My Store","version":"1.0","type":"link"}
