There is a lot you can learn about disc golf discs. One of the key factors that every player needs to understand is disc stability. Disc stability refers to how a disc behaves in flight—whether it flies straight, turns, or fades. Getting familiar with the different types of stability and how to read disc flight numbers will help you choose the right discs for your game.

Understanding Stability: Overstable, Stable, and Understable

In disc golf, there are three main categories of disc stability: overstable, stable (neutral), and understable. Each type of stability affects how the disc flies once you throw it.

• Overstable: An overstable disc tends to fade or hook left (for a right-hand backhand throw) towards the end of its flight. These discs are predictable in windy conditions and ideal for shots that need to finish with a strong fade. Overstable discs are great for experienced players who need reliability in challenging conditions, or as utility discs to get around corners when you need it. Our favourite overstable discs include the Kea, Tara Iti, and Kahu XG
  

  

• Stable (neutral): A stable or neutral disc flies straight with minimal turning or fading. These discs are easier to control and are excellent for beginners or for shots that require accuracy. Stable discs are predictable and versatile, making them essential for consistent throws. Our top picks for neutral discs are the Wonder and Pekapeka
  

  

• Understable: An understable disc tends to turn right (for a right-hand backhand throw) during flight, especially when thrown with power. These discs are great for new players because they are easier to throw far without needing a lot of arm strength. Understable discs are also handy for shots that need to turn or “flip” during flight. When reaching for an understable disc, you can’t go wrong with a Piwakwaka or Firehawk
  

  

Flight Numbers: What Do They Mean?

You may have noticed that most disc golf discs come with a set of flight numbers. These numbers are key to understanding the stability of a disc and how it might behave when you throw it. There are four numbers to pay attention to:

1. Speed (1-14): This number refers to how fast the disc needs to be thrown to achieve its full flight potential (note: this is not how fast the disc goes). Higher-speed discs require more power to control. New players are better off starting with discs that have lower speed numbers (6-9), like midranges or fairway drivers.

2. Glide (1-7): Glide measures the disc’s ability to stay in the air. Discs with higher glide ratings are ideal for long-distance shots. For new players, discs with more glide will help cover more ground with less effort.

3. Turn (+1 to -5): Turn represents how much the disc will veer to the right (for right-hand backhand throws) during the high-speed part of its flight. An understable disc will have a negative turn rating (e.g., -3 or -4), making it easier to flip or turnover during flight.

4. Fade (0-5): Fade refers to how much the disc will curve left at the end of its flight. Overstable discs have a higher fade number, usually between 3 and 5, which means they will have a stronger finishing hook.

By understanding these flight numbers, you can predict how a disc will fly and select the right discs for your skill level and shot type. For example, if you’re looking for a disc that flies straight and fades left at the end, you might choose a disc with a Speed 7, Glide 5, Turn 0, and Fade 3 rating.

How Stability Affects Your Game

For new players, it’s essential to start with discs that have less fade and turn, as these will be more forgiving and easier to control. Understable and stable discs are great choices because they allow you to focus on improving your form without fighting against the disc’s flight path.

Once you develop more power and control, you can start experimenting with more overstable discs, which are better suited for more technical shots or playing in windy conditions.
