Overstability

Overstability refers to a characteristic of a disc golf disc that describes its tendency to resist turning or hyzering to the right (for a right-handed backhand thrower) during flight. A highly overstable disc will fly straight for a longer distance before a pronounced fade to the left at the end of its flight. This resistance to turning is a key factor in a disc's flight path and is influenced by its design, including rim width, wing shape, and the disc's overall weight. Overstable discs are generally favored by players who throw with a lot of power, as they are less likely to turn over and lose distance. They are also useful for high wind conditions, as their stability helps them cut through the wind without being blown off course. Conversely, understable discs are more prone to turning to the right. A disc's stability is often categorized on a scale, with higher numbers indicating greater overstability. Factors like the material composition and wear on a disc can also subtly alter its stability over time.
