Flight Ratings System

Flight Ratings are broken into four main categories: Speed, Glide, Turn, & Fade. These characteristics can be used to rate various aspects of each disc's flight. Each disc has a distinct "personality"; the flight path that makes that disc unique. Flight Ratings can be used to compare our discs. Once you have thrown one of our discs, you can use the flight rating numbers to compare it to any of our other disc models. We have over 50 models to suit a wide range of players and their throwing techniques. To learn more about what each of these characteristics mean, refer to the chart below. Flight Ratings are based on a backhand throw.

SPEED| Speed is the ability of the disc to cut through the air. Speed Ratings are listed from 1 to 13. Discs with high numbers are faster. Faster discs go farther into the wind with less effort. Slower discs take more power
to throw, but have less of a chance
to fly past the basket.


GLIDE| Glide describes the discs ability to maintain loft during flight. Discs with more glide are best for new players, and for producing maximum distance (especially
              downwind). Glide is rated from 1 to
              7. Beginners looking for more
              distance should choose discs with
              more glide.

TURN| High Speed Turn is the
tendency of a disc to turn over or
bank to the right (for RHBH throws)
during the initial part of the flight. A disc with a +1 rating is most resistant to turning over, while a -5 rating will turn the most. Discs rated -2 to -5 make good roller discs.

              FADE| Low Speed Fade is the discs
              tendency to hook left (for RHBH
              throws) at the end of the flight. Fade is rated from 0 to 5. A disc rated 0 will finish straightest, while a disc rated 5 will hook hard at the end of the flight. Discs with a high fade rating are predicable even in wind.

Discs Made With...
  • Star | Star Plastic will retain flight ratings for a long period of time, with added grip.
  • Champion | Champion Plastic will retain flight ratings for a long period of time.
  • Pro | Pro Plastic will start slightly less overstable and the driver models will have more glide.
  • DX | DX Plastic will start more overstable and with use will match the ratings. With continued use, the DX plastic will eventually become more understable than the ratings.
For more information on plastic types, check out the Plastic Types Overview.

Brief Description of Terms...
  • Stability is a description of the disc’s flight path.
  • Understable means a flight that turns right (RHBH throw).
  • Stable is a flight that doesn’t turn.
  • Overstable refers to a flight that turns left (RHBH throw).
Understable discs are much more speed sensitive than stable or overstable discs. An understable disc will often fly stable to overstable at low speed. Beginners tend to throw discs at lower speeds.
For more information on these terms or others, refer to our Glossary of Terms.

Innova's flight ratings are not meant to describe the exact flight of any disc model. They are to be used to compare between models. For instance, a Wraith at 11, 5, -1, 3 is a faster type than the 10 speed models and slower than the 12 and 13 speed models. The Glide, Turn, and Fade cannot be compared to other speeds, but can be compared to other discs at the same speed. This way the Wraith can be compared to a TeeRex and Max on the same line.
The exact flight for any disc is dependent on the particular material it is made with, such as Champion, Star, Pro, R-Pro, or DX. It is also dependent on the throwers style and speed. Champion plastic tends to produce the most high speed stable discs (other than special runs of Star Lite), followed by Star, DX, Pro, and R-Pro.
