Zusammenfassung:	The utility model relates to a four rotor crafts, including the fuselage, first support arm, second support arm are installed to the front end symmetry of fuselage, and third support arm, fourth support arm are installed to the rear end symmetry of fuselage, and it has one set of rotor all to install on first support arm, second support arm, third support arm, the fourth support arm, and the fuselage upper surface sets up vortex breaker. The utility model has the advantages of 1, the turbulent boundary layer is surperficial attached to the wing, reduces the frictional resistance of air effectively. 2, the elasticity film stores the kinetic energy that the air flows for film elastic deformation's potential energy to again, release the energy to the air current in through vibrations, kinetic energy in order to improve the air current delays airflow separation, reduces pressure drag.
