RING WING DRONE

THE SO-CALLED RING WING DRONES ALWAYS INTERESTED ME AND I DECIDED TO DO SOMETHING ABOUT IT (10 IN ROTORS GIVE YOU A PICTURE ABOUT ITS SIZE). LOWER ELLIPTICAL WING USE NACA 2412 AIRFOIL, UPPER SOME MODIFICATION OF CLARK Y. VENTRAL AND DORSAL TAIL IS SIMPLE SYMMETRICAL SPLINE IN FORM OF AIRFOIL (I THINK THAT THEY DON'T NEED ANY FURTHER REFINEMENT). I WAS SLOPPY AT THE JUNCTION OF THE HORIZONTAL TAIL AND SPONSON, BUT IT'S NOT IMPORTANT FOR THIS LAYOUT (I LEFT IT SUCH AS IT IS). ENJOY
