Description

The FrSky Tandem X20S ACCESS represents a significant evolution in radio control technology, integrating a true simultaneous dual-band RF system. The TD system combines 900MHz and 2.4GHz frequencies not merely as a backup but as an active, coordinated link, delivering unprecedented 4ms latency and exceptional resistance to interference. This design ensures reliable control and telemetry feedback for demanding FPV racing, long-range exploration, and complex multirotor applications.

Built around the powerful and user-configurable ETHOS operating system, the transmitter offers a highly intuitive interface via its 800×480 color touchscreen. The chassis features CNC-machined metal construction, housing high-precision Hall-effect sensor gimbals for smooth, centerless stick feel. Integrated features such as a 6-axis gyro, haptic feedback, voice alerts, and a high-speed PARA wireless training system provide a comprehensive and modern pilot experience.

Key Features

  • TD Dual-Band Internal RF Module: Operates on 900MHz and 2.4GHz bands simultaneously for ultra-reliable control and telemetry with minimal 4ms latency.
  • High-Resolution Touch Interface: 800 x 480 pixel color LCD touchscreen provides clear visibility and direct menu navigation.
  • Premium Control Hardware: Features all-CNC metal construction, high-precision Hall-sensor gimbals, six quick-mode custom buttons, and two rear momentary buttons.
  • Advanced System Integration: Equipped with a built-in 6-axis gyroscope, haptic vibration alerts, voice speech output, and an external antenna with SWR warning.
  • Modern Connectivity & Power: Supports USB Type-C interface for battery charging and data transfer, and includes a Lite Type external module bay for expansion.
  • ETHOS Operating System: Delivers a powerful, flexible, and intuitive user experience for model setup, telemetry, and system configuration.

Applications

  • Professional FPV racing drones requiring ultra-low latency and maximum signal reliability.
  • Long-range and autonomous UAVs benefiting from the robust dual-band link and extensive telemetry.
  • Complex multirotor builds (cinematography, inspection) needing precise control and high channel count.
  • RC model training and buddy boxing using the integrated high-speed PARA wireless system.
  • General hobbyist aircraft, helicopters, and surface vehicles compatible with ACCST/ACCESS protocols.

Frequently Asked Questions

What is the benefit of the TD dual-band RF system in the Tandem X20S?

The TD system operates the 900MHz and 2.4GHz bands simultaneously, not as a simple fallback. This provides a more robust link that is highly resistant to interference and congestion, while also delivering an extremely low end-to-end latency of 4ms. It ensures maximum control reliability for critical applications like FPV racing and long-range flight.

What receivers are compatible with the Tandem X20S ACCESS transmitter?

The transmitter is compatible with FrSky receivers using the ACCST D16 (v2.x), ACCESS, and the native TD protocols. It ships with a TDR6 6-channel ACCESS receiver. For full TD dual-band functionality, a matching TD-series receiver is required to utilize both frequency bands concurrently.

Can I charge the internal battery via USB, and what is the recommended pack?

Yes, the transmitter features a USB Type-C port that supports charging the internal 2S Li-ion battery pack. The system operates within a voltage range of 6.5V to 8.4V. FrSky recommends using their specially designed 2S Li-ion battery packs for optimal performance and safety.
