FrSky TD MX OTA 2 4G 900M 4CH Tandem Dual Band Mini Receiver Low Latency Long Range Black Box Function PWM SBUS Output for RC DroneOVERVIEW Neither like other FrSky 2 4G receivers nor 900M receivers the Tandem dual band series receivers work simultaneously at both 900M and 2 4G frequencies that means it can give not only low latency signal control but long control range with an enhanced level of high reliability and anti interference performance The Tandem series receivers adopt the triple antenna design that can give the multi directional coverage as wide as possible for the remote signal The 900M antenna comes with a newly designed small form factor but it has the equivalent high performance as the original 900M antenna TD MX offers 4 PWM channels on a small board with lightweight and it also has multiple ports onboard like SBUS Out SBUS In Signal Redundancy S Port Inverted S Port and FBUS 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 In addition the data PowerSignal related under unusual status during the flight can be recorded by Tandem receivers through the built in black box function SPECIFICATIONS Brand Name FrSkyItem Name TD MX Dual Band Mini ReceiverModel TD MXFrequency 2 4GHz900MHzDimension 26 22mm L W Weight 6 7gOperating Voltage 3 5 10VCompatibility Tandem series radioTD pr
