The Innova Teebird and the Discmania FD are the two discs most often handed to a player who says "I want something straight that isn't a midrange." Both are speed-7 fairway drivers. Both measure 21.1 cm across with a 1.9 cm rim. Two flight numbers separate them: the Teebird is a 7/5/0/2, the FD a 7/6/0/1. The FD has one more point of glide and one less point of fade, and those two points decide the rest.
The short version: the Teebird is more dependable in wind and the more precise placement tool, while the FD carries farther on the same throw and finishes softer.
The quick answer
- Pick the Teebird if: you want a control driver that holds its shape in a headwind, you throw enough power to make a 5-glide disc travel, or you want a placement disc with a definite, plannable finish.
- Pick the FD if: you want maximum straight distance from a 7-speed, you're still building arm speed, or you want a tunnel-shot disc that keeps flying instead of hooking out of the gap.
- The deciding number is fade. The Teebird's 2 fade always signs off left (for a right-hand backhand). The FD's 1 fade mostly runs out of gas. Which ending you want on a fairway drive settles this for most players.
Flight numbers compared
The physical dimensions here are identical, which is rare in a cross-brand comparison and makes the flight numbers unusually meaningful.
| Innova Teebird | Discmania FD | |
|---|---|---|
| Speed | 7 | 7 |
| Glide | 5 | 6 |
| Turn | 0 | 0 |
| Fade | 2 | 1 |
| Stability | Stable to overstable | Stable |
| Diameter | 21.1 cm | 21.1 cm |
| Height | 1.8 cm | 1.8 cm |
| Rim depth | 1.3 cm | 1.3 cm |
| Rim width | 1.9 cm | 1.9 cm |
| PDGA approved | 1999 | 2011 |
| Manufacturer | Innova | Discmania |
Both discs read as neutral through the first half of the flight, since zero turn on each means neither is designed to flip right under power. The difference is entirely in what happens after the disc slows down. If you want a refresher on what the four numbers describe, our flight numbers guide works through each one.
Why are the dimensions identical?
The two discs share a factory. Discmania spent its early years as a Finnish company that designed molds and had them manufactured by Innova under license, and the original FD was one of those discs: PDGA-approved on November 13, 2011 and sold at the time under the Jackal name and stamp. The Teebird had already been in Innova's catalog since May 3, 1999.
That shared production history is why a Teebird and an FD feel so similar in the hand: same diameter, same rim depth, same wing width. In 2019 Discmania split from Innova and moved production in-house, and the retooled FD was re-approved by the PDGA on November 9, 2021. Collectors and tournament players sometimes distinguish the Innova-made and Discmania-made FDs for small differences in feel and stability, so if you're buying used it's worth knowing which era you're getting.
What the extra point of glide actually does
A 6 glide on a 7-speed driver is high. Most fairway drivers in this class sit at 4 or 5, and the FD's glide is the single biggest reason it outdistances discs with the same rim width. On a smooth, flat release the FD hangs in the air noticeably longer and keeps converting spin into forward travel after the Teebird has started to sink.
That matters most to players who don't yet generate big arm speed. Glide is the number that rewards a slow throw: a disc that floats gets more flight time to work with, so the FD gives a developing arm carry the Teebird doesn't. It's also why the FD is a reasonable first fairway driver and the Teebird generally isn't.
Glide cuts the other way when precision is the goal. A floaty disc keeps traveling past the spot you aimed at, and on a tight approach or a short fairway shot with trouble behind the target, the Teebird's lower glide is a feature: it puts the disc down closer to where the line ends. Our guide to glide covers the trade-off in more depth.
What the extra point of fade actually does
The Teebird's 2 fade gives every throw a definite ending. Thrown flat, it tracks straight for most of the flight and then eases left in the last stretch. That's enough movement to aim right of the target and let the disc walk back, and enough resistance that a moderate headwind doesn't push it over. It's the behavior that made the Teebird a tournament staple for decades.
The FD's 1 fade barely constitutes a finish. It's a stable disc that flies its line and drifts a little at the very end. For a tunnel shot bounded by trees on both sides, that's exactly right: the disc doesn't develop a mind of its own halfway down the gap. For a shot where you're relying on the fade to bring the disc back around a dogleg, it isn't enough disc.
In wind
This is the clearest separation between them. Wind adds turn to every disc, so the more overstable of two otherwise-matched molds is the better headwind option, and here that's the Teebird by a full point of fade. Headwind fairway drives are one of the shots the Teebird is built for, and Champion-plastic Teebirds run more overstable still when fresh, which is what most players reach for on a gusty day.
The FD does have a wind answer, but it's a plastic answer rather than a mold answer: fresh C-Line FDs run slightly more overstable than S-Line and hold up better into a breeze. A worn S-Line FD in a headwind will turn over. If you're regularly throwing into wind and want one disc for it, the Teebird is the more honest choice; if you want to stay in the Discmania family, the FD2 (7/4/0/2) or the FD3 (9/4/0/3) are the molds built for it.
How they age
Both discs improve with wear, and both let you tune the schedule through plastic choice.
- Champion Teebird: runs more overstable when new and beats into a stable, dependable workhorse over a long life. The pick if you want your Teebird to stay a Teebird for seasons.
- Star / GStar / Pro Teebird: grippier premium runs that wear in more gradually than Champion.
- DX Teebird: breaks in fastest and becomes one of the most reliable beat-in fairway molds in the sport.
- C-Line FD: firm and long-lived, slightly more overstable new. The headwind and forehand configuration.
- S-Line FD: softer, grippier, more neutral out of the box, and the faster path to a turnover disc.
- G-Line and Active Premium FD: the two less common runs, worth trying if neither C-Line nor S-Line suits your hand.
Many FD owners carry two: a fresh C-Line for wind and forehands, a beat-in S-Line for straight-to-turnover lines. The Teebird equivalent is a Champion and a worn DX. If plastic is the deciding factor for you, our Champion vs Star breakdown covers the Innova side.
Two very different résumés
The Teebird has one of the deepest pedigrees in the sport. 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 too. It was a faster reworking of the popular Gazelle and quickly took over that disc's market share, and for several years after its release it was the farthest-flying disc in disc golf: in 2002 Ken Jarvis used a DX Teebird to throw 247 m (810 ft) and set the world distance record.
The FD's claim is commercial rather than historical. It was Discmania's first fairway driver and is now one of the brand's three best-selling molds of all time, alongside the DD3 and the P2. It has introduced a lot of players to the brand.
How to choose
- How much power do you have? If you're under roughly 300 feet on a fairway drive, the FD's glide does more for you than the Teebird's fade. If you can already make a 7-speed finish its flight, the Teebird's control is worth more.
- What do you want at the end of the flight? A predictable left finish you can plan approaches around points to the Teebird. A disc that keeps going straight until it lands points to the FD.
- How windy is your home course? Exposed and gusty favors the Teebird. Sheltered and wooded favors the FD.
- Which brand do you already throw? Neither disc is better enough to justify breaking up a bag you know. Both slot cleanly into their own family's stability ladder.
For a lot of players the answer is both, in different slots: the FD as the straight, glidey placement driver, the Teebird as the stable one that handles wind and doglegs. They share a rim, so switching between them costs you nothing in feel.
If neither is quite right
- Discmania FD2 (7/4/0/2). Effectively the FD with a Teebird's finish and less glide. The obvious pick if you like the FD's feel but need more fade.
- Innova TeeBird3 (8/4/0/2). A flatter, faster remold of the Teebird that's better suited to forehands.
- Innova Thunderbird (9/5/0/2). The Teebird's flight shape on a wider rim, for players who overpower a 7-speed.
- Innova Leopard3 (7/5/-2/1). The understable option at the same speed, for hyzer-flips and slower arms.
- Innova Eagle (7/4/-1/3). A more overstable 7-speed for forehand approaches and hard headwinds.
