Loosens them up and makes them faster. You loose a bit of white wash stability.
Once you've mastered the foil in its full size, it's almost like making a new foil. Arguably how the foil should have been from the start.

Doesn't collect grass, faster, turns better, less dangerous. Don't get fone why the keep making winglets.

Keeps the foil from puncturing the wing sometimes. The eagle is a three year old antique though, it's amazing they still list it in the 2025 catalog. There's already a V2 SK8, they really need a better 10ish AR wing like a Lift 150X or Code S series.

Isn't the Eagle-X essentially the 10AR foil you're after? With the Jam already out and a new downwind foil on the way, it feels like F-One has most bases covered. That said, I agree with you-the Eagle may be an older design, but it set a benchmark in the industry and continues to hold its own. Many brands owe a lot to it for shaping and refining foil design trajectories.

Interestingly, some of those early 'antique' foils remain ahead of their time, outperforming even some of today's designs by renowned names. Just look at the Phantom-S or Escape as examples.

From what I have seen, people remove the winglets of foils (of any brand) because they are extremely dangerous for the rider and the gear.

The sheer number of foils that F-One is offering in 2025 is already pretty impressive. It's hard to imagine investing full price though into a design that old, would have to be like a 30% discount at least. I've spent some time on a 990 (with winglets) and while the glide seemed right in there with the Lift 150X, it was sluggish in roll and even more so in pitch. Some might consider that to be a good thing of course.
Eagle X I'd assume is another level at 12AR, and then the Momentum at 16.5AR looks great (for going straight downwind).
Interestingly enough they all have winglets

For prone foiling where you want both pump and turning the eagle is still as good as anything and possibly still the benchmark. 990 is a big foil for downwind and so is the 150.

For eagles in the surf it is standard practice to cut the tips off and cut the surf tails very narrow as both free them up more for surfing. You lose a little pump possibly. if your using a wing you would just use sk8's

I do wish they would update the Eagle, though. I feel like the Eagle X, with its 12AR, is a different wing. (Though I admit I haven't yet ridden one.) I like the ease of use of the Eagle, the fluid feel, and the ability to pump out of a hole. I've read the Eagle X is not so user friendly, which has turned me off a bit. I currently have an Eagle 990 and am deciding between an Eagle 790 or Eagle X 700 or 800 for faster wing powered wave riding.

You're better off pairing one of the new monobloc stabs with your 990. The DW145 for flat line blasting, the 161W for anything else. Eagle X's are pretty easy imo. Marginally higher stall speed, but plenty of glide and paired with the right tail, they turn pretty well.

what X's have you paired with what tails, and what did you find out? Thinking of getting a 700 or 800 for winging and pairing it with a 141w to losen it up a bit...

145DW for flat out speed - a stiffer setup but very fast
141 for looser riding or the new 135.


Honestly depends on what you want. If you had a 990 Eagle and a DW210 chopped to 7" on an XS fuse. I'd say get as small a monobloc as possible.
Otherwise, grab a sk8 v2 650 and pair it with a 135. Won't find a snappier setup than that.

I don't think there's much difference beyond the layup which won't make much difference with shorter spans.

Thanks! Fortunately, apparently the same shape but stiffer carbon construction. I was a little worried. But for my weight the v1 is stiff enough.

Says it all when the new shape looks the same! I love my SK8

I cut mine off because they almost cut the arch of my foot when sitting or getting on and off the board. Like having a knife right into the heart of your foot. By far the most dangerous foil detail that I have encountered and it only took one touch to make me run to to the garage and get them off of the wing. They are like vertical daggers.

I kept the winglets on my Eagle 990 but cut them down and rounded the shape significantly, using a Dremel tool and sanding. I'm sure they are not quite as efficient like this, but I don't notice any difference. I think they are safer this way and arguably even safer than if I had cut them off completely. The tips of many foils without winglets are also like daggers. Mine now has a small flat upturned tip that isn't very sharp.

Anyone having experience with cutting the winglets off the Eagle x? There is one for sale where I live with a poorly epoxy repaired winglet which I was thinking of buying for a good price and chopping the winglet. Bad idea?

surprises me that if they are so good as every owner bangs on, then why is it necessary to chop and trim them

Same reason you take training wheels off a kids bike, or size down from a behemoth 120L board.
Also, yes you can cut winglets off an X. Doesn't make them as loose, but they're pretty good.

Most of the extra stiffness is in the tips. A bit heavier as well.
