They won't be able to deliver on their spec. Not even close. https://www-aerokurier-de.translate.goog/elektroflug/lilium-weitere-experten-unterstuetzen-kritik/?

  After reading your article I came to one conclusion: RUN, don't walk from Lilium. They are obviously tricking people who don't know a single thing about airplane engines. Lilium responded to the aerokurier article on Monday with an email in which our experts were accused of having set the hover efficiency of the drives far too low with an efficiency of 20 percent. Lilium, on the other hand, claims that values "of 85-95% are the industry standard for turbo fan levels". According to Lilium, this mistake should have been noticed by any industry expert. Lilium is right with regard to the efficiency of turbofan engines viewed in isolation, as they are standard today on all high and fast flying airliners. However: There are no turbo fans installed on the Lilium Jet. They are jacketed propellers driven by electric motors.
