FrSky TW MX Receiver

by FrSky
Type: Receivers


TWIN series TW MX receiver features a new stable TW protocol which benefits from simultaneously integrating dual active 2.4G frequency bands. The TW active-active protocol is different from the general active-standby redundancy solutions (where one receiver takes over signal control only when the other is in Failsafe mode); with the TW protocol, dual 2.4G frequency bands are active on the TW series receiver at the same time.

This receiver is designed for RC users who want to benefit from resilience and long-range in their radio communications; typically, tens of kilometres is achievable. The TW MX receiver is lightweight, and its smaller size occupies less space which makes it very suitable for users who have constraints with limited installation space and weight.

As a micro receiver, the TW MX receiver is equipped with 2x 2.4G antennas. The signal output ports include one SBUS output channel and 4 PWM output channel ports. TW MX receiver also supports telemetry functions through FBUS / S.Port. By setting the TW MX to use FBUS protocol in the ETHOS system, the signal control and telemetry can be connected to any device that supports FBUS protocol through only one line to achieve bidirectional transmission, also simplifying the model build using fewer wires.

In addition, TW MX also supports 4ms race mode with ultra-low latency. When combining race mode with TW series resilient dual 2.4G solution, racers have a fast, stable, and reliable signal in racing competitions without fear of signal loss due to interference.

Simple transmitter but a little big
