The lack of a coiled cable isn't really a problem for me. You do need to use some care in where you put it so it doesn't get tangled, but I haven't had a real problem. I'm in and out of an S76 all the time, and I have added a clip to the cable to clip it to my survival vest while walking around outside, so it doesn't dangle and drag the ground and my hands are free for loading baggage, etc. It's easy enough to do, and may not be necessary for everyone. You need an adapter, which is sold lots of places - Sporty's, Marv Golden, etc, for connecting the two GA plugs to a helicopter plug.
