yes, you can bind the Sensor to the 1st gen Spektrum rxs. the 3000 and 3001 (maybe a 3001s if thats a legit model). but i know you can do the ones from the original DX3 and maybe some of the early 3.0 RXs.
you have to run the TX in DSM (as nomadio labled it- Da Slow Mode) to work the specy rxs. to use the DSM mode, you need the Beta version of the software installed.
now, hit menu, and scroll down to the advanced section on the TX. go into the advaced section, and scroll down to the Rx Type menu. push the plus button, and change it to DSSS Beta, and confirm you want to run in DSSS Beta mode. once you confirm, you can then fire up the rx and you should be able to bind to it.
