Total 85kwh battery cell weight is 900lbs plus uber strong housing of 300lbs.
That makes 1200 lb or about 500kg, the total takeoff wt is 600kg, which minus the 200kg payload leaves an airframe of 400kg, 100kg short of the battery weight by itself - doesn't add up.
Go to the website, look for the photo looking up at the machine and see that everything is forward of the wing - it will not fly.
See also the pop-out cylinders for hovering - when they pop back in, the occupants' feet are crushed.
Looks very pretty, but somebody is playing with himself.
