You have actually answered your own question.
There is no difference in the radios between RW and FW.
The plug on the end of the headse cord is different. I fly RW and FW. The cord that drapes across my left knee in the C172 I don't want draped across my left knee in a Bell 206 - something to do with using the collective.rolleyes: Most helicopters have the radio jack in the overhead panel or rear bulkhead for that reason.
I have a DC headset and HU5 helmet, both with curly tails, with different mics. I sometimes have to swap the mics because of the radio setup but not because it is FW or RW. For FW I have a 3' extender and adaptor with the dual FW plugs. Works a treat.
