Finishing and testing the tri-lip-wing single copter
Since it has three lip wings I'm calling this concept tri-lip-wing single copter. The testing is during my vacation at Myrtle Beach, since it was too cold in Canada.

Cutting parts for the lip-wing single copter
The most efficient rotorcraft is a single rotor, so this is what I'm building. I'm cutting the parts on my new CNC machine. The parts are from Home Depot blue extruded polystyrene foam. I'm also adding a layer of fibreglass for rigidity.
