A flying wing needs an airfoil with a low pitching moment, and those create less lift with the same wing area than regular airfoils. A low pitching moment is achieved with reduced or even negative camber in the rear part of the airfoil (google "reflex airfoil" for more info and pictures).
To first approximation, a flying disc is simply an axi-symmetric wing with an elliptical cross-section. Of course, most ordinary wings would be unstable if simply thrown through the air, but the essential mechanics of its lift are mostly ordinary. The lift on a body is described by the lift equation,
Imagine three lines running through an airplane and intersecting at right angles at the airplane’s center of gravity. Rotation around the front-to-back axis is called roll. Rotation around the side-to-side axis is called pitch. Rotation around the vertical axis is called yaw.
During takeoff, air accelerated behind the prop (known as the slipstream) follows a corkscrew pattern. As it wraps itself around the fuselage of your plane, it hits the left side of your aircraft's tail, creating a yawing motion, and making the aircraft yaw left.
Findings – This study reveals two key parameters to evaluate the flight performance of a disc: its coefficient of lift-to-drag. ratio (CL/CD) and, more importantly, its coefficient of pitching moment (CM). The latter influences the tendency of the disc. to yaw from its intended path, and the former influences its throwing distance.
Flight dynamics is the science of air vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle's center of gravity (cg), known as pitch, roll and yaw.

Spinning involves simultaneous roll, yaw, and pitch as it develops a helical or corkscrew path nose down. An incipient spin is the autorotation prior to a vertical descent path, while a fully developed spin begins once the vertical path is achieved.
