Stable is a term that describes a disc's stability, its overall flight pattern, i.e. where it lands compared to from where it was thrown.
* Tend to fly rather straight and basically don’t turn when thrown flat, straight and with average power.
The Stability of Innova discs is described in more detail by Turn and Fade, the 3rd and 4th numbers in the flight ratings, that together determine a disc's overall stability.
* High Speed Turn refers to the initial part of the flight when a disc has a tendency to turn or bank to the right for right handed back hand (RHBH) throwers, left for LHBH thrower. Ratings are from -5 to +1.
Lower ratings of -5 to -2 contribute to understability. A disc with a -5 rating offers the least resistance therefore will turn the easiest while a +1 rating is most resistant to turning. Discs rated -5 to -2 make good roller discs and are considered understable.
* Low Speed Fade refers to the end of the flight. All discs tail off or hook to the left for right handed back hand (RHBH) throwers (right for LHBH throwers), but some will hook harder than others. Fade rates how fast or hard a disc will hook or fall at the end of the flight. Ratings go from 0 to 5 with 0 meaning almost no fade.
Lower ratings of 0 - 1 contribute to understability. A disc rated 0 will finish straightest with the least fade. Discs with a low fade rating are the more understable. A disc rated 5 will fade or hook hardest at the end of the flight. Discs with a high fade rating are predictable even in wind and considered more overstable.
Add the numbers of Turn and Fade.
If the total is -1 to - 5, it's understable with - 1 being just slightly understable and -5 being very understable.
If the total is 0, a disc is straight.
If the total is 1 to 5, it's overstable with 1 being straight or just slightly overstable and 5 being extremely overstable.
