Understanding Disc Golf Flight: Turn vs. Fade
If you're new to disc golf, you've probably heard experienced players talk about a disc's "turn" and "fade." These terms are crucial for understanding how a disc flies and how to throw it effectively. While they both describe aspects of a disc's mid-flight and end-of-flight behavior, they are distinct characteristics.
What is "Turn"?
The turn, often referred to as "understable flight" or simply "turning," describes a disc's tendency to curve away from the direction of the initial throw (the flight plate's edge that's leading). This usually happens at higher speeds when the disc is thrown with a bit of an anhyzer angle (the outside edge of the disc angled downwards). Think of it as the disc wanting to roll over onto its back. For right-handed backhand throwers, a strong turn means the disc will curve to the right. For left-handed backhand throwers, it means a curve to the left.
Factors influencing a disc's turn:
- Speed: Higher speeds generally induce more turn.
- Angle of Release: Throwing with an anhyzer angle will promote turn.
- Disc Stability: Understable discs are designed to turn more easily.
- Arm Speed: A faster arm speed will also contribute to a disc turning more.
What is "Fade"?
The fade, often referred to as "overstable flight" or "hook," describes a disc's tendency to curve back towards the intended target line as it slows down. This happens later in the flight path and is more pronounced with discs that have a higher "fade" rating. For right-handed backhand throwers, a strong fade means the disc will curve back to the left. For left-handed backhand throwers, it means a curve back to the right.
Factors influencing a disc's fade:
- Disc Stability: Overstable discs are designed to fade more.
- Arm Speed: While higher arm speed can cause more turn, as the disc slows down, its inherent overstability will dictate the fade.
- Angle of Release: A hyzer release (outside edge angled upwards) will exaggerate the fade.
- Wind: Headwinds can make a disc fade out earlier and harder, while tailwinds can reduce fade.
The Interplay of Turn and Fade
Most discs will exhibit both turn and fade to some degree. The combination of these two flight characteristics dictates the overall S-shaped or C-shaped flight path of a disc. A disc with a lot of turn and a little fade might finish to the right (for a right-handed backhand). A disc with little turn and a lot of fade will likely finish hard to the left.
Understanding the turn and fade ratings on a disc is crucial for selecting the right disc for a particular shot:
- High Turn, Low Fade: These are understable discs, good for beginners, hyzer flips, and achieving long, gliding shots that finish right (RHBH).
- Low Turn, High Fade: These are overstable discs, good for strong headwinds, predictable finishes, and carving sharp dogleg left (RHBH) shots.
- Balanced Turn and Fade: These are stable discs that fly relatively straight before a gentle fade.
Think of it this way:
The turn is the disc's initial desire to go in one direction (away from the intended line), while the fade is its final effort to correct and come back towards the intended line.
Disc Flight Ratings Explained
Most disc manufacturers provide a set of four numbers on their discs, often molded into the plastic. These are the flight ratings:
- Speed: How fast the disc needs to be thrown to achieve its intended flight.
- Glide: How long the disc stays in the air.
- Turn: The disc's tendency to turn to the right (for RHBH) at high speeds.
- Fade: The disc's tendency to fade to the left (for RHBH) at the end of its flight.
The Turn rating is typically a negative number (e.g., -1, -2, -3), with larger negative numbers indicating more turn. The Fade rating is typically a positive number (e.g., 1, 2, 3), with larger positive numbers indicating more fade.
Frequently Asked Questions (FAQ)
How does arm speed affect turn and fade?
Arm speed is a significant factor. A faster arm speed will generally make a disc fly more understable, meaning it will turn more and fade less than it would with a slower arm speed. Conversely, a slower arm speed might cause a disc to seem more overstable, as it won't achieve the speed needed for significant turn, and its natural fade will be more prominent.
Why do some discs turn more than others?
Discs are designed with varying degrees of stability. Understable discs have a rim shape and weight distribution that makes them more prone to turning. Overstable discs, on the other hand, are designed to resist turning and exhibit a stronger fade. The "turn" rating on a disc's flight numbers is a good indicator of how much it's designed to turn.
When would I want a disc with a lot of turn?
A disc with a lot of turn is useful for several scenarios. Beginners often benefit from understable discs because they are more forgiving and can achieve distance with less arm speed. Experienced players use them for "hyzer flips," where they throw an understable disc on a hyzer angle, and it flips up to flat, turning over for a long, straight flight. They are also great for shots that need to finish to the right (for a right-handed backhand golfer) without having to throw an anhyzer.
Why is fade important in disc golf?
Fade is crucial for shaping shots, especially when navigating obstacles or dealing with wind. A strong fade allows for predictable finishes to the left (for a right-handed backhand golfer), which is essential for approaching greens or executing dogleg shots. Overstable discs with a strong fade are also reliable in headwinds, as they are less likely to turn over and get carried away.
