You can build GREAT flying rc airplanes out of flat dow corning foam.. NO airfoil of any type and they fly great...You can build so light that with todays small electric power setups you can almost fly anything. Also as mentioned above the drone/quad copters can use a body on them to simulate some thing other than a 4 head helicopter.
Great photo of Hillary coming in for a landing at her next campaign appearance. . .

Slow down!
