Yes, and it always has been. From the Moller Sky car to the Lilium here, making the craft is the easy bit (well, apart from the thrust vectoring but with modern computers that's solvable). Getting it to run for more than 2 minutes with a realistic load is the hard part. Those small ducted fans are horribly inefficient by the way, a regular shaped plane with a pusher prop and the wingspan of a glider would have a much better chance achieving the range (but no VTOL).

Too good to be true usually isn't true.
