FrSky TW R10 10-Channel Dual 2.4GHz TW Receiver
The FrSky TW R10 is a 10-channel Twin (TW) protocol receiver running dual 2.4GHz simultaneously for enhanced reliability and range performance. 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. The TW R10 has 10 configurable channel ports. CP1 supports PWM, SBUS Out, FBUS, S.Port, or SBUS In; CP2–CP10 support PWM, SBUS Out, FBUS, or S.Port. A compatible FBUS device can share control and telemetry on one line when the port and device are configured correctly.
Manufacturer specifications (TW R10)
Dual-active 2.4GHz TW protocol; 10 configurable channel ports (CP1: PWM / SBUS Out / FBUS / S.Port / SBUS In; CP2–CP10: PWM / SBUS Out / FBUS / S.Port); SBUS Out supports 16/24-channel mode; three 2.4GHz antennas with IPEX1 connectors. Dimensions: 64.6 × 16.6 × 12.4 mm; weight: 9.4 g; operating supply: 3.5–12 V; receiver current: no more than 120 mA at 5 V; external AIN voltage measurement: 0–35 V (10:1 divider). OTA firmware updates and basic black-box recording are supported, subject to compatible firmware.
Why We Recommend This
The TW R10 suits pilots using a TW-capable FrSky RF system who want simultaneous dual-2.4GHz operation and 10 configurable channel ports. Its selectable PWM and digital-bus outputs offer flexibility for fixed-wing installations, subject to the CP1/CP2–CP10 mode differences documented by FrSky.

Frequently Asked Questions:Which FrSky transmitters are compatible with the TW R10?
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.

What is the TW (Twin) protocol and how does it differ from Tandem (TD)?
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. Tandem (TD) uses both 2.4GHz and 900MHz simultaneously for extended range. TW is optimized for dual-2.4GHz reliability; TD adds 900MHz for long-distance and penetration. Compatibility depends on the transmitter's RF hardware — verify before pairing.
How do the 10 configurable channel ports work?
Each of the 10 configurable ports supports PWM, SBUS Out, FBUS, or S.Port. CP1 additionally supports SBUS In for signal redundancy; CP2–CP10 do not list SBUS In as a selectable mode. Set each port to the required supported mode in ETHOS and verify the connected device's interface and power requirements.
How do I use FBUS for telemetry on the TW R10?
Set a configurable channel port to FBUS mode in ETHOS and connect only devices confirmed to support the selected FBUS interface. The FBUS connection can carry control and telemetry bidirectionally over one signal line. Verify wiring, firmware, and adequate power distribution for connected servos and sensors before use.
Does the TW R10 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.
What is the difference between the TW R10 and TWSR8?
The TW R10 has 10 configurable channel ports; the TWSR8 has 8 channels plus a built-in gyro stabilizer for self-leveling flight modes. Choose the TW R10 for more channel flexibility; choose the TWSR8 for stabilization without a separate gyro unit.
Does FPV Builds RC offer setup support for the TW R10?
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
