This is the Spektrum 24 Remote Receiver Extension.
The Spektrum 24 Remote Receiver Extension is the cable that runs between the main receiver and the remote (satellite) receiver. This cable has a female connector on both ends. If you wish to lengthen your remote receiver cable please see the other cables of various lengths or look into the extensions with quick disconnects (SPMAJST3 & SPMAJST6). You can utilize a standard servos extension between the two ends of the extension with quick disconnect.
