CB-18 audio recording cable connects GoPro and helicopter headsets, capturing clear pilot and ground audio for flight training. Purpose built for helicopters with a U-174/U plug, the CB-18 cleanly captures cockpit audio. Use it to connect your GoPro or any 3.5 mm voice recorder to the helicopter intercom and record everything you hear and say, including intercom and ATC communications. Plug the 3.5 mm end into your recorder and the U-174/U end into the standard helicopter jack. The in-line helicopter connector also links to your airplane headset so you don’t occupy an intercom port, keeping your cockpit setup flexible.
