The FrSky Tandem TD R12 Receiver delivers next-generation RC link reliability by operating simultaneously on both 2.4GHz and 900MHz frequencies in Tandem (TD) mode. Unlike conventional single-band receivers, the TD R12 provides ultra-low latency control, long-range performance, and enhanced anti-interference capability all at the same time.

Equipped with a triple antenna system (2× 2.4GHz and 1× 900MHz), the TD R12 ensures multi-directional signal coverage for dependable communication in demanding flying environments. Its dual XT30 power inputs feature intelligent balancing consumption, automatically drawing power from the higher-voltage source to maximise redundancy and safety.

A built-in Black Box module records power and signal data during unusual flight conditions, while Over-The-Air (OTA) firmware updates keep your system current without removing the receiver. With 12 fully configurable channel ports supporting PWM, SBUS, FBUS and S.Port, the TD R12 is ideal for complex builds and advanced telemetry integration using the FBUS protocol.

Designed for pilots who demand resilience, redundancy and long-range reliability, the TD R12 is perfectly suited to large models, performance aircraft and precision builds.
