FrSky Tandem TD R18 2 4GHz900MHz 18CH Dual Band Low Latency Long Range PWM SBUS Output Mini Receiver With Audio Switch Set for FPV RC DroneThe Tandem dual band receivers are unlike any other FrSky 2 4Ghz or 900Mhz receivers they work simultaneously at both 900Mhz and 2 4Ghz frequencies That means Tandem receivers provide not only the low latency signal and long range control also benefits from enhanced level of high reliability and anti interference performance The Tandem series receivers adopt the triple antenna design that provides multi directional wide coverage for the remote signal The 900Mhz antenna is a newly designed small form factor but has the equivalent high performance as with previous 900mhz antennas The data PowerSignal related under unusual status during the flight can be recorded by Tandem receivers through a built in black box module and TD R18 can additionally save the complete and long term data ControlFlight Attitude data log etc by SD card through the external module TD R18 also provides a socket that can be used to connect the switch panel NFC Switch panel to enable the built in Power Switch function The configurable 18 channel ports are a big feature of TD R18 each channel port can be assigned as PWM SBUS FBUS or S Port With the FBUS protocol the Tandem series receivers can open up the possibility of seamlessly pairing with multiple telemetry devices Neuron ESC Advance Sensors etc as well as simplifying the builds setup TD
