Frequently Asked Questions

What protocols does the FrSky TANDEM X18's internal RF module support?

The integrated TD-ISRM module supports FrSky's TD mode for simultaneous dual-band operation, the ACCESS protocol on both 2.4GHz and 900MHz bands, and is backward compatible with the ACCST D16 protocol (V2 firmware or later). This provides flexibility for use with a wide range of existing and new FrSky receivers.

Can I use an external module with the TANDEM X18 transmitter?

Yes, the transmitter features a rear Lite-version external module bay. This allows you to add compatibility with third-party RF systems such as ExpressLRS, Crossfire, or other long-range modules, expanding your control options beyond the built-in FrSky protocols.

What type of battery does the TANDEM X18 use, and how is it charged?

The transmitter is designed for a 2S Li-ion battery pack (6.5V - 8.4V operating range). It includes a built-in recharge system with a USB Type-C port for convenient charging. The recommended charging current is 1A or less.

Is the TANDEM X18 suitable for drone racing due to its latency?

Yes. In TD mode, the system achieves an end-to-end latency as low as 4ms, which is critical for responsive control in high-speed FPV racing and freestyle flying. The high-precision Hall gimbals and ETHOS system further contribute to a precise and tunable piloting experience.
