Yes Chris, no conceptual difference, latest Spektrum adopt the cable solution, to which cable only few kind of connectors can be crimped, just verify which kind of connector you have on the receiver pcb.
On early Spektrums (which I have) this antenna can't be used because the quarter wave wiskers (the antenna) were directly soldered to the PCB.
Forget hobbyking, item number on ebay, 310748652056, you get 2 for AU$5.09 DELIVERED!! I check a lot of stuff is cheaper on ebay, Hobbyking is losing it's touch and going for higher priced items, such as quads, you can hardly buy a decent model here for under $200 delivered, ebay is the new hobbyking! again?
