What is an overstable disc in frisbee golf? To understand stability, you need to have an overview of what the 4 numbers on the disc are. Briefly, it is:
1. Speed: How fast the disc can fly through the air.
2. Glide: How long the disc stays up through the flight.
3. Turn: How much the disc goes to the right at the start of the flight (for right-handed backhand)
4. Fade: How much the disc goes to the left at the end of the flight (for right-handed backhand)

Overstable discs have a lot of fade, and little slip and spin. For beginners, overstable discs can be used if you want the disc to finish hard to the left (for right-handed backhand players). For advanced players with a lot of power, overstable discs are also used for long, controlled throws, as well as for throws against the wind. Headwinds cause the disc to spin more, so an overstable disc will neutralize that effect. See our ultra-stable discs.
The opposite of an overstable disc is an understable disc. These have less fade, and more glide and turn. These are mainly used by beginners who want to gain more distance. But again it comes at the expense of control, as there is an even greater risk of the disc turning to the right. For advanced players, less stable discs are suitable for throwing into the wind. Downwind makes the disc spin less, so an understable disc will neutralize that effect. See our understable discs.
