=== Stability ===
Stability is the measurement of a disc's tendency to bank laterally during its flight.  A disc that is over-stable will tend to track left (for a right-handed, backhand throw), whereas a disc that is under-stable will tend to track right (also for a right-handed, backhand throw).<ref>{{Cite web |title=Disc Talk, Pt. 2: Rim Width, Stability, Weight, Durability {{!}} UDisc |url=https://udisc.com/blog/post/disc-talk-pt-2-rim-width-stability-weight-durability |access-date=2023-04-11 |website=Release Point - The UDisc Blog |date=31 March 2020 |language=en}}</ref> The stability rating of the discs differs depending on the manufacturer of the disc. Innova Discs rate stability as "turn" and "fade". "Turn" references how the disc will fly at high speed during the beginning and middle of its flight, and is rated on a scale of +1<ref name="innovadiscs.com">{{Cite web|title=Flight Ratings System|url=https://www.innovadiscs.com/home/disc-golf-faq/flight-ratings-system/|website=Innova Disc Golf|language=en-US|access-date=2020-05-01}}</ref> to −5, where +1<ref name="innovadiscs.com"/> is the most overstable and −5 is the most understable. "Fade" references how the disc will fly at lower speeds towards the end of its flight, and is rated on a scale of 0 to 6, where 0 has the least fade, and 6 has the most fade. For example, a disc with a turn of −5 and fade of 0 will fly to the right (for right handed, backhand throw) the majority of its flight then curl back minimally left at the end. A disc with a turn of −1 and a fade of +3 will turn slightly right during the middle of its flight and turn hard left as it slows down. These ratings can be found on the discs themselves or from the manufacturer's web site. Discraft prints the stability rating on all discs and also provides this information on their web site. The stability ranges from 3 to −2 for Discraft discs; however Discraft's ratings are more of a combination of turn and fade with the predominance being fade.

Spin (rotation) has little influence on lift and drag forces but impacts a disc's stability during flight. Imagine a spinning top: a gentle nudge will knock it off its axis of rotation momentarily, but it will not topple over because spin adds gyroscopic stability. In the same way, a flying disc resists rolling (flipping over) because spin adds gyroscopic stability. A flying disc will maintain its spin rate even as it loses velocity. Toward the end of a disc's flight, when the spin and velocity lines cross, a flying disc will predictably begin to fade. The degree to which a disc will fade depends on its pitch angle and design.<ref>{{Cite web|url=http://www.triumphbooks.com/the-definitive-guide-to-disc-golf-products-9781629372044.php?page_id=21|title=The Definitive Guide to Disc Golf|website=www.triumphbooks.com|access-date=2016-04-21}}</ref>
