The RingWing (green) is the most efficient at the assumed 330Kg weight.<\/figcaption><\/figure>\n\n\n\n

The lilium is clearly inefficient in hover, but their strategy (see lilium blog<\/a>) assumes “<\/strong>limited time period spent in the power-hungry hover mode” and instead optimises for “efficient cruise flight” and “low noise”.

However negotiating obstacles, to meet objective 1<\/a>, requires significant time in hover and low-speed flight, and high power would require expensive batteries and non-standard electrical components that are incompatible with the objective of an affordable vehicle<\/a>.<\/p>\n\n\n\n
