Spektrum SRXL2 DSMX Remote Serial Telemetry Receiver

The SPM4651T DSMX SRXL2 Serial Micro Receiver is an upgraded version of the SPM4649T, offering longer control range, improved telemetry performance, and a fast SRXL2 serial protocol supporting up to 20 channels. Designed for helis, multi-rotors, and FPV setups, it features dual diversity antennas for stronger signal coverage, a simple bind button, and the reliability of Spektrum’s DSMX 2.4GHz technology. Its compact size and extended coax antennas make it ideal for installations where space, carbon fiber, or metal can interfere with signal strength.
