i just got a DX3 off another member here. and this question has probably been answered.. i just need a simple yes or no...

can i use any spektrum reciever with the radio? specifically the micro reciever? or the dsm2 one?

this is the DX3... not the 3.0 and not the DX3R

No to the DSM2 SR3100 from the DX3R. Or the SR3000HRS for the Futaba 3PK. Everything else works I believe, including the standard SR3000 and the SR3500 micro.
