Urban Aeronautics is now showing its ‘Fast Mule’ ducted fan UAV.
It’s supposed to exceed 250kts and it is, “is 20% larger and 50% heavier,” than the MULE UAV, which (from the UA Website) has a payload of about 750 lbs, so I’m guessing that this aircraft’s payload is in the ½ ton range.
It looks wicked neat, though.
