  • I was doing some market research on large electric power systems and I found this brushless motor:

    which can generate 65 lbs of thrust swinging a 30x10 prop.  4 of those would make 260 lbs lift.  The motor itself weighs under 4 lbs so if you could keep the weight of the batteries and vehicle under about 100 lbs then you could lift a light person.

     

    Ballpark between $16,000 and $18,000.
