Note that the Spektrum buddy jacks are not very robust..info from "milehighwings" which supplies cables and USB dongle for all makes of tx's (and very nice software). They reported that jack failures are a common problem with the Spektrums. I now use an old, well used futaba as controller.
Thanks, I'll hit radio shack for a stereo to mono adapter for the Phoenix USB dongle.
