Flight Charts

Flight Chart Explanation

On this page I will explain what the flight numbers mean and what exactly we mean with classifications such as "Stable-Understable".

Flight Charts:

We match the typical Innova flight charts with MVP's classifications such as Stable-Understable and rim width to give you the best idea possible of how a disc will fly prior to actually throwing it!

Overstable? Understable?

Overstable and understable can be confusing to new players but can be simplified very easily. An overstable disc simply wants to fall to the ground faster and will want to fade sooner and harder. An understable disc generates more lift which will make the disc "turn" or go the opposite direction that it naturally wants to fade. So for a right-hand back-hand thrower the disc wants to fade to the left and an overstable disc will fight harder to go to the left and an understable disc will turn to the right until it is going slow enough to fade. Understable discs generally have more glide than overstable.


Speed is simply how fast the disc needs to be thrown to achieve the expected flight ratings. Discs that are thrown below their speed rating will behave more overstable and discs that are thrown way above their speed rating will tend to turn. A good indicator of a discs speed is it's rim width.

The following video from Best Disc Golf Discs (Youtube) explains speed ratings very well:


Glide tells you how well the disc "sits" on the air. The higher the glide rating the better the disc will sit on a cushion of air allowing it to generally fly further.

The following video from Best Disc Golf Discs (Youtube) explains glide very well.


Turn is how much you can expect the disc to "turn over" when thrown at the discs speed. The higher the turn rating generally the more understable the disc. Understable discs are generally seen more beginner friendly because they will try to stay in the air.


Fade is how much a disc tries to fall back to the ground. The higher the rating the more the disc will try to fight to the ground. A more overstable disc will begin the fade phase of flight earlier and end up further away from the center of your throw.

Stability Ratings:

Our stability ratings are based on MVP's overstable to understable ratings. There is the following five ratings.


Discs that are highly reluctant to turning and want to fade back to the ground are overstable. Overstable discs typically are rated with 0 turn and 3 or more fade. Some of the most overstable discs even have lower glide ratings and the most overstable discs even have a positive turn rating!


Discs that have a small amount of turn and a larger amount of fade are generally considered Stable-Overstable. They will turn slightly and then fade back past the center line that you were aiming on.  These are the primary drivers that many professional bags are built around.


These discs are very straight. They may have a small amount of turn and fade. These discs are great for making it down a long tunnel shot.


 These discs generally offer the most distance potential. They typically have -2 or -3 turn and -2 or -3 fade. They will turn for you and will come back at the end of the flight to be close to the center line of your throw.


Understable discs generally have -2 or more turn with 1 or less fade. They will turn over for you and hold the line and will take a long time to fade. These discs are generally considered the best for new throwers.
