FrSky Tandem X20HD UpKit Radio Dual-RF Transmitter

The FrSky Tandem X20S Radio 900MHz/2.4GHz Dual Band Transmitter is designed to provide users with a comfy radio system packed with features. The full color touch display allows users to easily set up, edit, and create RC models. The dual-band RF system features the advantages of the FrSky 900MHz and 2.4GHz in one combined RF system. The TD dual-band RF system is characterized by true simultaneous dual-band remote control with telemetry, and superb end-to-end 4ms latency performance. When combined with ETHOS, a completely updated operating system, FrSky’s Tandem X20 Series provides users with a powerful, intuitive, and flexible experience to enjoy across the entire world of RC.

The Tandem X20 has been complemented with 6 customizable buttons on the front case that allows for quick switching between features, ideally to be used for flight modes. Additional 2 rear momentary buttons have been introduced to provide flexibility, in the ideal position for DLG pilots launch fingers no matter if you are left or right-handed.

The two side handle grips of Tandem X20 are made with a high-quality comfortable material, designed ergonomically to fit the hand very well. Both hall-gimbals are well-positioned which makes the sticks very close to the grip edge allowing for ease to reach and control, also the spring tension and the stick travel can be adjusted to 45° or 60°. This UpKit version supports rotating gimbals within an adjustable 8° L/R.

The TD dual-band RF system combines both the features and advantages of FrSky 900MHz and 2.4GHz RF together in one system. The TD features real simultaneous dual-band long-range control with telemetry that achieves reliable end-to-end 4ms latency while maintaining a robust and high-quality signal link. The entire range of TD, ACCESS & ACCST D16 receivers are supported. The built-in TANDEM RF System supports ACCESS and ACCST D16 protocols.
