Most of the late model Spektrum will bind to the the different receivers available.
However, if you own a
DX-6, it will
only bind to the AR6100 receiver. This is because the
DX-6 is a DSM-1 transmitter, the DX-6
i, and all the other Spektrum transmitters are now
DSM-2 which are backward compatable, and will have no problem running the AR6100.
