As the second R9 series receiver, R9 Slim includes all the advantages of the previous R9 long range receiver but with lower latency and a much more compact size. SBUS output plugs directly into the Pixhawk 2.1 Flight Controller. When used with the R9M Module this receiver is compatible with all the FrSky and TBS transmitters. The redundancy function ensures the security of your aircraft, and its tiny shape with the reduced weight is a no sacrifice option for long range and reliable connection with your aircraft.
