F-ONE WTF!? The WTF!? is F-ONE’s flagship competition freestyle kite, a pure, uncompromised, unbridled C shape kite with a fifth line, five struts and a rad attitude. For such an aggressive kite, with big power potential, the team were impressed with the smooth power delivery the WTF!? produces during general riding, and in its wind range where it builds speed very quickly to go into popped unhooked tricks. Of course, this style of kite isn’t sheet and go, you’ve got to work the kite a little to build some board speed before it fires into life. Speed is essential. Once trucking, the upwind ability is notably excellent, perfect for getting back to the competition area. Build wise, the kite is pretty beefy, and the large SUP style inflate valve allows for a nice high inflate pressure to be easily achieved. Stability unhooked is excellent with a minimum of trimming required, and very little flaring. It provides mind blowing pop and slack, and long downwind travel. It’s absolutely unflappable, particularly if you come out of a trick with a lot of downwind board speed. Looping produces a big wide arc with an enormous amount of pull. The overall riding experience is very engaging, and if you’ve come off a more mainstream freeride kite onto the WTF!?, you need to be on your game kite control wise, but once you have adjusted there’s so much more performance potential for freestyle. The kite turns on its tips in a big radius, there’s no power steering here, and you need some guns to get it to move, but the bar feedback is as perfect as it gets for this style of kite. This makes the WTF!? confidence inspiring. Although there’s a lot of power on tap, it lets you build trust with the kite quite quickly. For the seasoned rider, who has owned five line kites in years gone by, the kite is a fantastic nostalgia trip, reminding you how simple more mainstream kites have become to use and just how much performance a pure C shape has. For such an extreme design on the modern market place, it’s well behaved to handle. It’s not too grunty, and the stability really shines through. The front hang point settings work a charm, allowing a little more sheet change. It’s a very refined and honed product with a very specific audience in mind. If you’re very focused on freestyle, this kite is an excellent choice, and for competition style riding there are few rivals.
