Q: From the picture it appeares to be a single plug in, will it work with a helicopter plug, or is it fixed wing only? and it will record the radios as well as the pilots transmissions?
A: This adapter will work with any headset. The single plug that is in the picture is the jack that plugs into the tape recorder. The audio input is attached to the headset dome, so basically anything that you can hear while wearing the headset will be recorded.
