FrSky’s new TWIN X Lite series is a powerful radio system that simultaneously features dual 2.4G frequencies on the same receiver in TW mode. The TW active-active protocol is different from the general active-standby redundancy solutions. They have two 2.4Ghz internal RF antennas mounted to provide multi-directional and broader coverage for transmitting signals compared to a single antenna design. Taking advantage of these features, the TWIN system can provide less latency and higher reliability at a faster data rate with confidence.
The FrSky Twin X Lite series size and shape have been designed to make the radio compact, lightweight, and easy to carry. While the cheaper TWIN X Lite ($279.99) has a 3.5″ color touch-screen and 1GB internal memory, the more expensive TWIN X Lite-S ($339.99) has a 3.5″ high-brightness matte touch-screen and 4GB memory. Both versions feature 2x Momentary buttons, 2 x Sliders, and 4 x Switches.
In addition to the TW mode, TWIN X Lite S also supports ACCST D16, ACCESS, and ELRS 2.4G (Compatible) modes. Now, users can benefit from a wider range of compatible receiver options to choose from and bind to when building the drone.
The TWIN X-Lite S has an integrated 6-axis sensor that turns this FrSky transmitter into a motion-sensing controller to control the inputs of the drone during flight or use it to point a camera in the desired direction.
A 4000mAh Li-Po battery powers Frsky Twin X Lite and X Lite S transmitters. You can conveniently charge the battery through the Type-C port without removing it.
