A company have shown off an incredible flying machine - that you wear as a backpack. Australian firm CopterPack have launched what they say is the second generation of their aircraft. Footage taken in Sydney shows a pilot able to lift off from a standing position thanks to a pair sets of drone-style blades. They then appear to enjoy a controlled hover using two joysticks. Founder Matt Lipski says a safety tether was used for this demonstration flight. He explains: CopterPack Gen2 is an electric backpack helicopter with a self-levelling autopilot that is currently under development. "It utilises an all-new ducted fan control system which was successfully tested. "Also added is an LED lighting system for night flying and a Garmin G5 electronic flight instrument. "The purpose of this flight was to test the all-new control system and a safety tether was used. "The aim for the final design is to attain the following characteristics: long flight times; ultra safe; high speed; and can fly up to 10,000ft in altitude. "The next phase of development involves construction of the final design and the addition of safety features, followed by high speed forward flight testing and high altitude testing." CopterPack say the machine has a lightweight airframe constructed from carbon fibre honeycomb. "The unique characteristic of CopterPack is that your body becomes part of the aircraft," add the firm. Matt Lipski says CopterPack's cost will be known after the development of the final design is complete.
