What does it mean to have an understable disc in disc golf? To be able to answer that, it is important that you know the 4 numbers on the Frisbee. 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)

Understable discs have a lot of spin and slide, and little fade. This means that if the disc receives sufficient force, it will "turn over" and go to the right (for a right-handed backhand). It also means that throws with less power will stay in the air longer before the disc dumps to the left. The understable discs are mainly used by beginners who want to gain more distance. The extra distance comes at the expense of control, as there is a high 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.
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). 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.
