Just when you think all the vertical lift innovation is happening elsewhere you find out about a British company called 4×4 Aviation.
Their concept is to utilise a ducted fan propulsion system with power provided by a hybrid engine and energy storage system to deliver 20 foot ISO containers. It is scaleable from small unmanned system with a payload of 7-10kg right up to a 30 tonne ISO container.
Test flights of scaled demonstrator are planned for later this year.
So, good luck and all that!
We will have two.
