Description

The FrSky TANDEM X18 transmitter integrates the advanced TD dual-band RF system, combining 2.4GHz and 900MHz frequencies into a single, robust link. This design provides pilots with reliable long-range control and telemetry, supporting a wide array of FrSky receivers including TD, ACCESS, and ACCST D16 protocols. The internal TD-ISRM module ensures end-to-end latency as low as 4ms, critical for responsive FPV and drone piloting.

Built around the ETHOS operating system, the X18 offers a powerful and flexible user experience with a clear, color touchscreen display. Its structural design prioritizes pilot comfort with contoured grips, strategically placed sliders and switches, and additional trim levers for precise flight attitude adjustments. The chassis includes an integrated flash storage system and retains a TF card slot, while the rear Lite-type module bay allows for expansion with third-party external RF systems.

Key Features

  • TD-ISRM internal RF module supports simultaneous 2.4GHz & 900MHz TD mode, ACCESS mode, and ACCST D16 protocol.
  • ETHOS OS delivers an intuitive, touch-enabled interface with multi-language switching and hardware telemetry monitoring.
  • Ergonomic case with rounded hand grips, flat standing base, and six front-mounted quick-mode custom buttons.
  • High-precision Hall-effect sensor gimbals mounted on a metal panel for drift-free, long-lasting stick resolution.
  • Integrated haptic vibration alerts, voice speech outputs, and a high-speed PARA wireless training system.
  • USB Type-C recharge system for internal 2S Li-ion batteries (6.5–8.4V operating range).
  • Lite-type external module bay for compatibility with verified third-party long-range transceiver systems.
  • Backlit capacitive touchscreen with 480x320 resolution for clear visibility in various lighting conditions.

Applications

  • Primary transmitter for competitive FPV racing and freestyle drones requiring low-latency, dual-band control.
  • Long-range UAV and mapping platform control leveraging the 900MHz band for extended telemetry range.
  • Complex multirotor builds (e.g., heavy-lift hexacopters, cinematography rigs) utilizing the full 24-channel capacity.
  • Training setup for new pilots using the integrated high-speed PARA wireless buddy-box system.
  • Compatible ground control station for ArduPilot or PX4-based autonomous drones via ETHOS LUA scripts.

Frequently Asked Questions

What protocols and receivers are compatible with the FrSky TANDEM X18?

The TANDEM X18's internal TD-ISRM module is compatible with FrSky's TD, ACCESS, and ACCST D16 protocols. It supports the full range of corresponding receivers, including the included TDR6, all ACCESS receivers, and ACCST D16 receivers with firmware version 2 or later. The system can operate in simultaneous dual-band mode for enhanced link reliability.

How do I update the firmware or change settings on the TANDEM X18?

The TANDEM X18 uses the ETHOS operating system. Firmware updates and system configuration are managed directly through the color touchscreen interface. You can connect the transmitter to a computer via USB to transfer firmware files to the internal flash storage or TF card. ETHOS provides an intuitive menu for model setup, channel assignment, and telemetry configuration.

What type of battery does the transmitter use, and how is it charged?

The transmitter is designed for a 2S Li-ion battery pack within a 6.5V to 8.4V operating range. It features a built-in USB Type-C charging circuit, allowing you to recharge the internal battery by connecting a standard 5V/2A USB power adapter to the port. The system monitors battery voltage and provides haptic or voice alerts for low power conditions.

Can I use external RF modules with the TANDEM X18 for other protocols like ExpressLRS?

Yes. The transmitter includes a rear Lite-type external module bay. This bay supports third-party modules that have passed FrSky's compatibility verification, including many popular ExpressLRS, Crossfire, or R9M Lite modules. This allows you to leverage the X18's ergonomics and ETHOS system while using your preferred long-range RF link.
