The FrSky TWIN TW MX is a compact dual 2.4GHz micro receiver designed for RC pilots who want the enhanced resilience, long-range capability and low latency of FrSky's TWIN TW protocol in a lightweight, space-saving package.

The TW MX uses FrSky's active-active dual 2.4GHz protocol, with both frequency bands operating simultaneously rather than relying on a conventional active-standby redundancy arrangement. This provides a highly resilient radio link and is designed for demanding RC applications where maintaining a reliable connection is important.

With its small 32 × 17 × 4mm footprint and low 3.8g weight, the TW MX is particularly well suited to models where installation space and weight are limited. It features two 2.4GHz antennas, four PWM output ports and an SBUS Out connection supporting 16CH or 24CH modes.

The receiver also supports FBUS and S.Port telemetry. When configured for FBUS through an ETHOS system, control and telemetry can be transmitted bidirectionally through a single connection to compatible FBUS devices, helping reduce wiring and simplify model builds.

For racing applications, the TW MX supports 4ms Race Mode with telemetry, combining ultra-low latency with the resilience of the TWIN dual 2.4GHz system.
