FrSky Tandem X20R X20RS Dual-Band RC Transmitter
Technical Highlights
Dual-Band RF Architecture
The integrated dual-band RF system supports multiple operating combinations across 2.4GHz and 900MHz. Available operating modes include TD dual-band, TW dual-2.4GHz, ACCESS and ACCST D16 for compatible FrSky receivers.
Multi-Link Redundancy Support
Compatible TW and ACCESS R9 receivers can be connected through SBUS input and output interfaces to create a redundant control configuration using multiple independent RF links.
ETHOS Control Environment
The ETHOS operating system provides model programming, telemetry display, mixers, flight modes, logical functions, custom widgets and configurable control assignments through a graphical touchscreen interface.
Outdoor High-Brightness Touchscreen
The adjustable color touchscreen provides a clear interface for model configuration, telemetry monitoring and system management in indoor and outdoor operating environments.
Version-Specific Hall Gimbals
The X20R uses M20 high-precision Hall-sensor gimbals with metal panels. The X20RS upgrades to full-CNC MC20R Hall-sensor gimbals with ten ball bearings, adjustable travel and rotatable gimbal panels.
Integrated Feedback and Training Functions
Built-in voice output, haptic vibration, a six-axis gyroscope sensor and the PARA wireless training system support advanced alerts, model control and instructor-student applications.

FAQ
What are the FrSky Tandem X20R and X20RS?
The X20R and X20RS are advanced dual-band RC transmitters powered by the ETHOS operating system. They support multiple FrSky RF protocols, telemetry, programmable model functions and up to 24 control channels.
What is the difference between the X20R and X20RS?
The main difference is the gimbal system. The X20R uses M20 high-precision Hall gimbals, while the X20RS uses full-CNC MC20R gimbals with ten ball bearings, adjustable travel, rotatable panels and independent left and right stick vibration.
Is a receiver included?
No. This product package does not include a receiver. A compatible FrSky receiver must be selected separately according to the required protocol, frequency and application.
Which receiver protocols are supported?
The transmitter supports compatible ACCST D16, ACCESS, TD and TW receivers. Receiver compatibility may depend on the selected RF mode, firmware and regional frequency version.
Which frequency bands are supported?
The integrated RF system supports 2.4GHz and 900MHz operation, including dual-band and compatible dual-2.4GHz operating modes.
How many channels are available?
The X20R and X20RS support up to 24 control channels when used with a compatible receiver and RF configuration.
What is ETHOS?
ETHOS is FrSky's transmitter operating system. It provides model programming, mixers, telemetry screens, logical functions, custom widgets, flight modes and configurable control assignments.
What display is used?
The transmitter uses an adjustable backlit color touchscreen with an 800 × 480 resolution and an outdoor-readable display design.
Can the transmitter battery be charged through USB Type-C?
Yes. The USB Type-C interface supports data transfer and compatible 2S Li-ion battery charging. Use a suitable 5V USB adapter capable of supplying more than 2A.
Is the transmitter battery included?
The standard package described here does not include the transmitter battery. Use a compatible 2S Li-ion battery that fits the battery compartment and voltage requirements.
Does the transmitter support an external RF module?
Yes. A Lite Type external module bay is provided for compatible external RF modules.
Can the transmitter be connected to a computer?
Yes. The USB Type-C interface supports firmware management, data transfer and access to compatible internal or removable storage.
B2B Procurement FAQ
Which version should buyers select?
Select the X20R for M20 Hall gimbals or the X20RS for full-CNC MC20R gimbals with additional adjustment and independent stick-feedback functions.
What should buyers confirm before ordering?
Buyers should confirm the X20R or X20RS version, transmitter color, regional frequency configuration, required receiver protocol, battery requirements, firmware version and package contents.
