FrSky TANDEM X18RS Radio Transmitter - TD-ISRM RS Edition

The FrSky TANDEM X18RS isn't just a radio—it's a full-blown RF control command center dressed like a transmitter. Designed for serious FPV pilots and RC aficionados who need precision, reliability, and a side of swagger, this version comes equipped with the TD-ISRM RS RF module—a dual-band (900MHz + 2.4GHz) powerhouse that laughs in the face of signal dropouts.

Whether you're flying long-range with LoRa or managing tight latency with 2.4GHz, the X18RS supports multiple protocols including ACCESS, R9, ACCST D16, TD, and TW. Yes, all of them. Simultaneously. And with SBUS IN/OUT ports, you can set up redundant receiver backups because flying blind is so last season.
