the dx3r can do ALL spectrum receivers. but your better off getting the dsm2 receiver so you can use the dsm2 technology.
the dx3s(and all other spectrum radios) can use any dsm receiver . that's all the spectrum receivers except the sr3100
A couple other exceptions: The SR3000HRS receiver only works with the Futaba 3PK HRS mode. Which are kinda rare I as far as I know.
And transmitters other than the DX3R won't work with either the SR3100 or the new SR3520. Any DSM2 Rx needs the 3R.
The Losi job works with all except the HRS and the 3100/3520 as far as I know.
