Jetpack helicopter type
Australian company CopterPack posted a video with a successful lift-off on the ground and a manned flight in a few seconds of her propeller jetpack.
The frame is made of carbon fiber. Powered by electricity. Judging by the video, the flight can last no more than a minute. The system is equipped with automatic stabilization. There is no more information available.
Under the cut are a couple of historical analogs of “helicopter jetpacks”.
