FrSky TW R8 Dual 2.4GHz Receiver with 8-Channel Ports
The FrSky TW R8 is an 8-channel Twin (TW) protocol receiver running two simultaneous 2.4GHz links for enhanced reliability. The TW (Twin) protocol uses two simultaneous 2.4GHz RF links utilizing FSK and LoRa. Both links operate as part of the TW RF system to provide RF redundancy, interference resistance, and robust control performance. Eight configurable channel ports (PWM, SBUS, FBUS, or S.Port) give you full connectivity flexibility. FBUS support enables clean single-wire bidirectional telemetry with ADV sensors and the Neuron ESC. OTA firmware updates via ETHOS keep the receiver current without cables.
Why We Recommend This
The TW R8 is a clean 8-channel receiver for pilots using a TW-capable FrSky RF system who want simultaneous dual-2.4GHz operation without onboard stabilization. Eight configurable channel ports and FBUS telemetry support make it a flexible choice for sport aircraft and trainers. FPV Builds RC provides U.S.-based product support, receiver-selection assistance, and setup guidance for FrSky products purchased through our store.
Frequently Asked Questions:Which FrSky transmitters are compatible with the TW R8?
This receiver requires a FrSky transmitter or RF module capable of operating the TW (Twin) protocol. Compatible options include FrSky TWIN-series transmitters (X14, X14S, X14RS, X-Lite S) with native TW support, TW-capable Tandem/RS-series transmitters such as supported X18RS and X20R/X20RS configurations, and compatible ETHOS transmitters equipped with the FrSky TWIN Lite Pro external RF module. Compatibility depends on the transmitter's RF hardware, selected RF protocol, module support, and compatible firmware. Browse all options at https://www.fpvbuildsrc.com/frsky-receivers
What is the difference between the TW R8 and the TWSR8?
Both are 8-channel TW dual-2.4GHz receivers. The TWSR8 (Stabilized Receiver) adds a built-in 3-axis gyro/accelerometer for self-leveling flight modes — Auto-Level, Stabilization, and Knife-Edge. The TW R8 is the non-stabilized version — ideal for aircraft with a dedicated flight controller or any build where you want direct control without onboard gyro processing.
What is the TW (Twin) dual-2.4GHz protocol?
TW (Twin) uses two simultaneous 2.4GHz RF links utilizing FSK and LoRa. Both links operate as part of the TW RF system to provide RF redundancy, interference resistance, and robust control performance — without requiring a 900MHz antenna.
How do I configure the 8 channel ports?
Each port can be independently assigned as PWM, SBUS Out, FBUS, or S.Port in your transmitter's ETHOS settings. This lets you mix standard servo outputs with digital bus connections on the same receiver without external decoders.
How do I use FBUS for telemetry on the TW R8?
Assign a channel port to FBUS mode in ETHOS. Connect ADV sensors (FAS current sensor, GPS, VARI) or a Neuron ESC to that port. Bidirectional telemetry flows on a single wire — sensor readings stream live to your radio screen with no hub needed.
Does the TW R8 support OTA firmware updates?
Yes. Where supported by the receiver and RF system, FrSky OTA functionality allows compatible receiver firmware operations through a compatible FrSky transmitter/RF system. Ensure the transmitter RF firmware and receiver firmware are compatible and follow the current FrSky/ETHOS firmware procedure for this receiver.
Does FPV Builds RC offer setup support for the TW R8?
Yes — we're a U.S.-based FrSky dealer happy to help with binding and FBUS setup. Browse our full FrSky receiver range at https://www.fpvbuildsrc.com/frsky-receivers
