title_body: Does the FS-R6B receiver work with the JJPRO EM-16 transmitter? If I need a new receiver and can't find one that is exactly the same as the one that came with the radio, can I get one with the same amount of channels and from the same company and use it with the radio?
  Specifically, I need to know if this receiver works with this radio.
upvoted_answer: There are various digital protocols, and many receivers are able to handle more than one protocol (and so can a few transmitters).
  It looks like that transmitter uses &quot;AFHDS 2A&quot;, so you need a receiver that can handle that.
  That receiver (FS-R6B) says &quot;AFHDS&quot; on the label, and there's a big complicated chart (the 5th image) showing which receivers handle AFHDS 2A, but I can't see the FS-R6B on the chart so it's not much help. The binding instructions imply that it might do both.
