The Innova Eagle (7/4/-1/3) and the Innova Teebird (7/5/0/2) are two speed-7 fairway drivers from the same manufacturer, approved under two months apart in 1999 and both still in production. They share a diameter, a rim width and a rim depth, and both sat in Ken Climo's bag. The difference is what each disc does at the end of the flight.
The short version: the Teebird holds a line and signs off gently, while the Eagle shows a point of turn under power and then finishes harder left.
The quick answer
- Pick the Teebird if: you want a pinpoint fairway driver for tight wooded lines, you value a finish you can plan around over a dramatic one, or you want one control driver that does most fairway jobs.
- Pick the Eagle if: you throw forehands, you play exposed courses with real headwind, or you want a fairway driver that reliably comes back at the end of a flex line.
- The deciding numbers are turn and fade. The Teebird's 0/2 is a neutral disc with a modest finish. The Eagle's -1/3 is a flex shape: a touch of rightward movement while the disc is fast, then a stronger fade than the Teebird ever gives you.
Flight numbers compared
Three of the four physical measurements are identical, which makes the flight numbers unusually informative here.

| Glide | 4 | 5 |
| Turn | -1 | 0 |
| Fade | 3 | 2 |

Neither of these is a beginner disc, and both are listed that way for the same reason: a 7-speed with real fade needs enough arm speed to reach the end of its flight before the fade takes over. If you are still building power, the understable Leopard3 (7/5/-2/1) or the glidier Discmania FD (7/6/0/1) are the friendlier discs at this speed. Our flight numbers guide works through what each of the four numbers describes.
Where the two flights diverge
The Teebird is the simpler flight of the two. Zero turn means it is not designed to move right under power, so a flat release tracks straight for most of the flight and then eases left at the end. That is the behavior that made it a tournament staple for decades, and it is why it gets handed to players who want a fairway driver they can aim.
The Eagle reads differently on paper. A single point of turn paired with three of fade is a flex shape: the disc gives up a little ground to the right while it is still moving fast, then comes back harder than the Teebird does. The net result is still an overstable disc, since the fade outweighs the turn, but the path there has more shape in it. Thrown on a hyzer it holds the angle and finishes.
One point of glide separates them as well, and it points the same direction as everything else. The Teebird's 5 gives it more flight time to convert into distance; the Eagle's 4 puts the disc down sooner, which is a feature when there is trouble behind your target. If the words behind those numbers are new to you, understable vs overstable covers the vocabulary.
What each one is actually for
These discs are not competing for the same slot in a bag as often as their matching speed suggests.
The Teebird is the placement disc. Innova's own listing of what it is for reads: pinpoint fairway drives where placement beats distance, tight wooded lines that demand a straight finish, headwind fairway shots, and stable hyzers and controlled flex lines. It is a disc you throw when you have a specific landing zone in mind.
The Eagle is the wind and forehand disc. Its jobs are forehand approaches, headwind fairway drives, and overstable hyzer lines, plus control distance for a strong arm. Forehand approaches sit at the top of the Eagle's list and do not appear on the Teebird's at all, which is the single clearest split between the two molds.
Both are listed as headwind options, which is worth being precise about. The Teebird resists a headwind well for a disc with zero turn, especially in Champion plastic, which runs more overstable when fresh. The Eagle resists more, because it has an extra point of fade to spend. On a gusty exposed course the Eagle is the one that still does what you asked; on a sheltered wooded course the Teebird's straighter line is more useful more often.
Same rim, different profile
The two molds match on diameter, rim depth and rim width, so they feel closely related in the hand and switching between them costs nothing in grip. The listed height is where they part: 1.6 cm for the Eagle against 1.8 cm for the Teebird. With rim depth identical, that difference sits in the flight plate, making the Eagle the lower-profile disc of the pair.
That matters mostly when you are buying. Flat, gummy Eagles are the most prized examples, and Calvin Heimburg's bag is the one usually named as the ideal. Handle a few before you pick one.
Two discs from the spring of 1999
The Eagle was approved first, on March 12, 1999, alongside the Eagle-L variant. Innova had built it as a faster, glidier successor to the Banshee, and at release it was the farthest-flying disc in the company's lineup. It became one of Innova's most popular molds quickly and has stayed a tournament disc ever since, through bags belonging to Ken Climo, Barry Schultz, Calvin Heimburg, Jeremy Koling, Gregg Barsby and Ricky Wysocki.
The Teebird followed on May 3, 1999, as a faster reworking of the already popular Gazelle, and quickly took over that disc's market share. For several years after its release it was the farthest-flying disc in all of disc golf: in 2002 Ken Jarvis set the world distance record with a DX Teebird at 247 m (810 ft). It was Ken Climo's favorite disc, and outside the Roc no mold is as closely tied to the twelve-time world champion's name. Steve Brinster, Avery Jenkins and Paul Ulibarri all threw it.
Both molds later picked up a less stable "L" sibling, for players who found the premium-plastic versions too stable during the Champion Edition era. The Eagle-L is penned EL on the bottom, against the standard Eagle-X's EX, and it is still made in limited runs; CE Eagles from the early 2000s are sought-after collector items. The Teebird-L (7/5/-1/1) became nearly as popular as the original.
Plastic, and how each one ages
Both discs are sold across Innova's range, and plastic choice moves each one further from or closer to the other.
- Champion and KC Pro Eagle: these retain their overstability much longer than the other runs. The pick if you want the Eagle to stay a headwind and forehand disc.
- Star and Pro Eagle: these beat in over the years into straight-to-fading workhorses.
- DX Eagle: flies fairly neutral, so it is the least overstable way to own the mold.
- Champion Teebird: runs more overstable when fresh and beats into a stable, dependable workhorse over a long life.
- DX Teebird: breaks in fastest and becomes one of the most reliable beat-in fairway molds in the sport.
The Teebird is also produced in Star, GStar and Pro; the Eagle's fifth run is KC Pro rather than GStar. Our Champion vs Star breakdown goes deeper on the two runs both discs share.
The overlap between the molds is real. A beaten-in Star Eagle ends up as a straight-to-fading workhorse, which is close to the flight a Teebird gives you new. Owning a premium Eagle and a base-plastic Teebird keeps the two further apart than owning both in the same plastic.
One quirk applies to the Eagle and not the Teebird: Eagles vary noticeably from run to run, with some flying closer to a Firebird and others closer to an FD. Buying an Eagle sight unseen is more of a gamble than buying a Teebird.
How to choose
- Your forehand share. The Eagle lists forehand approaches as its first job and the Teebird does not. If a meaningful portion of your shots are sidearm, that settles it.
- How exposed your home course is. Open and windy rewards the Eagle's third point of fade. Wooded and sheltered rewards the Teebird's straighter line.
- What you want the last third of the flight to do. A gentle finish you can aim around points to the Teebird. A definite hook back points to the Eagle.
- Which one you already own. Adding the other is usually a better move than swapping. They occupy different slots despite the shared speed, and the matching rim means no adjustment in feel.
If neither is quite right
- Innova Thunderbird (9/5/0/2). The Teebird's flight shape on a wider rim, for players who overpower a 7-speed.
- Innova TeeBird3 (8/4/0/2). A flatter, faster remold of the Teebird, better suited to forehands.
- Innova Firebird (9/3/0/4). The step up in overstability from the Eagle, for forehands and headwinds that need more disc.
- Innova Leopard3 (7/5/-2/1). The understable option at the same speed, for hyzer-flips and slower arms.
- Discmania FD2 (7/4/0/2). A neutral 7-speed with a Teebird-style finish, if you want that flight outside the Innova catalog.
