FrSky TWIN Lite Pro RF Module
The FrSky Twin Lite Pro RF module brings the TW (Twin) dual-2.4GHz protocol to any radio with a JR-style lite module bay — including the FrSky X-Lite S and third-party radios with a compatible module bay. The module outputs two simultaneous 2.4GHz RF links using FSK and LoRa in TW mode, giving compatible ETHOS transmitters with a lite module bay access to TW protocol — including X-Lite S, X18RS, X20R/X20RS configurations that support an external TW module, and other radios with a JR-style lite module bay. TW receivers (TW R6, TW R8, TW R10, TWSR8, TW MX) all bind directly to the Twin Lite Pro RF module.
The Twin Lite Pro connects to the host radio via the lite module bay protocol and passes control data from the transmitter to both 2.4GHz output channels simultaneously. This makes it ideal for upgrading an existing radio to TW protocol without replacing the transmitter itself. ETHOS is required on the host radio for full TW protocol support and OTA receiver updates.
Why We Recommend This
The Twin Lite Pro is the module bay solution for adding TW dual-2.4GHz capability to any radio with a lite-sized module slot — our pick for pilots who want TW receiver compatibility on a transmitter that didn't ship with TW built in. 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 radios are compatible with the Twin Lite Pro RF Module?
The Twin Lite Pro fits radios with a JR-style lite module bay. FrSky's own X-Lite S is the primary compatible radio. Third-party radios with a compatible lite module bay may also work — check your radio's module bay specification against the JR lite standard before ordering. For the X14 and X14S, the TW module is built in — you don't need the external module. Browse our full transmitter lineup at https://www.fpvbuildsrc.com/frsky-transmitters
Which receivers work with the Twin Lite Pro RF Module?
All FrSky TW (Twin) protocol receivers bind to the Twin Lite Pro: TW R6, TW R8, TW R10, TWSR8, and TW MX. Standard ACCESS and ACCST receivers do not use the TW protocol and will not bind to this module. Browse all TW receivers at https://www.fpvbuildsrc.com/frsky-receivers
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 needing a 900MHz antenna.
Do I need ETHOS on my radio to use the Twin Lite Pro?
Yes. Full TW protocol support — including binding TW receivers and performing OTA firmware updates — requires ETHOS on the host transmitter. The module outputs the TW signal, but ETHOS manages the protocol settings and receiver pairing. Older firmware versions of OpenTX may not fully support TW protocol features.
What range can I expect from the Twin Lite Pro?
Range is comparable to other FrSky 2.4GHz receivers — typically several kilometers in open air depending on antenna orientation and environment. The dual-2.4GHz active-active system improves reliability against single-channel interference rather than extending raw range beyond standard 2.4GHz limits. For greater range, consider a Tandem (TD) system using 900MHz.
Does FPV Builds RC offer setup support for the Twin Lite Pro?
Yes — we're a U.S.-based FrSky dealer happy to help with module installation and receiver binding. Browse our full FrSky receiver range at https://www.fpvbuildsrc.com/frsky-receivers
