WIND GRADIENT & FETCH
The use of anecdotal evidence to try to support a generalisation is always suspicious. Epic's owners continually posting videos & images of kites flying in conditions without whitecaps and claiming "5 knots" are misleading; obviously wind gradient http://en.wikipedia.org/wiki/Wind_gradient and/or short wind "fetch" http://en.wikipedia.org/wiki/Fetch_(geography) are involved.
RELATIVE KITE PERFORMANCE
The ONLY way to gauge the RELATIVE performance of kites in light winds is to fly them side-by-side, with similarly experienced riders and similar boards.
LIGHT WIND KITE DESIGN
It is simply not possible for the Epic Infinity (V1, 2, or 3) to surpass significantly the performance of every other light wind kite in existence. There is NOT enough energy for ANY kite to perform in "2-4 knots of wind". With BIG light wind kites, various modifications have been tested over many years: Fast-turning big kites need to be fat (i.e. lower aspect ration & long middle struts), but the payoff is poorer upwind ability and slightly inferior low-end. Narrower (high aspect ratio) kites go upwind better, but turn more slowly. e.g. Flysurfer's "Speeds" are very narrow, but very SLOW turning. There is no such thing as a fast-turning, ultra-low end, exceptional upwind, easily relaunchable kite with a lot of range; there's always a trade-off.
EPIC INFINITY'S DEEP LUFF CURVE CAUSES PROBLEMS
The problem with designing a ~16m kite (Infinity V2 and V3) for "light winds" is that the luff curve has to be very deep to "milk" as much low end as possible. This causes the kite to sit VERY deep in the window, leading to the problems "Laughingman" outlined, i.e. poor upwind ability, a tendency to yank the rider downwind, extremely poor top-end, and poor ability to absorb gusts.Laughingman wrote:1. (for me) it sat too far back in the window making edging up wind almost impossible unless you were on a light wind specific board
2. and if you were on a light wind board it was easy to lose speed control since edging against it was near impossible … but it still yanked me downwind because it sits so far back in the window.
For obvious reasons, a ~16m kite will NEVER have the low end of a larger kite. The Epic Infinity probably shouldn't even be called a "light wind kite"; 16m kites are more "light-medium" wind kites. To make up for the lack of surface area, the Infinity's designers have deepened the luff curve, with obvious NEGATIVE tradeoffs.
Epic Infinity V1 & V2 INFERIOR
The Epic V2 Infinity was tested alongside other light wind kites (e.g. North Dyno 18m) and was found to be inferior.
Objective testing of previous versions of the "Infinity" showed it had inferior power to other kites in light winds: http://www.thekiteboarder.com/2011/05/e ... te-review/davesails7 wrote:I've been riding a 2011 18m Dyno for the last few months and have been really impressed. I've ridden it while others rode…Epic Infinity…, so can compare low end by how I was able to get on the water vs. the others. Who knows what actual wind speeds were up in the air at the kite. I think side by side comparison is much more helpful than endless videos of a kite riding alone on glassy water.
vs. Infinity: Dyno was stable in the air, never fell out of the sky for 4 hours of light wind riding. Two guys with Infinities were struggling to keep their kites in the air most of the time.
The Infinity V3 failed in 8 knots (see below). The V2 performing in 5k? Complete bullshit.Dimitri M wrote: I have video of the Infinity V2 in action from 5 to 10 knots real soon. Did I say 5 knots!!!! No way..... !
Epic Infinity V3 INFERIOR
The INFERIORITY of the Epic Infinity V3 was demonstrated conclusively in a head-to-head comparison with the 19m Core. It failed THE major criterion of light wind kite performance: the ability to get the rider going early in LIGHT winds.

SupaEZ wrote:His kite needed more wind to get going.
I was 100 ft away from beach on a full plane in 8k. He was 10 ft away from the beach on a sub-plane working hard not to end up on beach also in 8k. Right before we crossed (dead onshore wind) … Made sure he saw me...i looked into the white of his eyes. Did a 6 ft air forward 1 1/2 transition with kite downloop to toeside and planed off on the other tack
For the short time we were both able to go out i did 5 type jumps/ transitions. Many with looping the kite effortlessly.
He was only able to get one 4ft air back roll transition and landed in an insufficient amount of water. He was then grounded.
End of story.
…the issue here is who is BS "ing" who here about LW performance.
I felt like i was riding against someone with a smaller size kite.....OOOPS i was !
Epic's Bad Sportsmanship & Fundamental Dishonesty
Recently, EPIC's ~16m V3 Infinity challenged a 19m kite to a "duel". Epic lost. During the duel, despite having plenty of opportunity to use line extensions and a surfboard, Epic refused to do so, "because (he) didn't need them". But to subsequently use this as an excuse for losing is …. pathetic and fundamentally dishonest. This fundamental dishonesty was compounded by outright slander, claiming the opponent had to swim out to get started.
Epic Infinity V3 Will LOSE Even More Low End
The Epic Infinity V3 is still being revised:
It is IMPOSSIBLE to give a kite more high end without compromising low end. Hence, the Epic Infinity V3 will become even more INFERIOR in light winds.DimitriM wrote:…we are still working on perfecting the High end of the INFINITY v3.
Epic Lies & Exaggerations
Epic's owners are well known to stretch the truth, e.g.:
Compared to the Core19m kite, the Epic Infinity V3 was noticeably INFERIOR; it certainly didn't have the "power of a 19m".Dimitri M wrote: Infinity V2 has the power of a 19 meter but turns like a 14 meter.
Until this vid surfaced, Epic was claiming light wind domination at this event. The inferiority of the Epic Infinity in light winds is demonstrated, as is the fundamental dishonesty of Epic in trying to portray otherwise. Epic struggling and then collapsing into the water while the Cabrinha LW kite blasts past. Compelling. Hilarious! And a savage indictment of Epic and its marketing. The Epic Infinity can NOT fly in ?7/8 knots, let alone 2-4 knots.
SUP-kiting in 9 Knots
Despite the "2-4" knot claims, the Epic Infinity CANNOT perform on a SUP until ~ 9 knots.

....Personally I like your kites, I just don't like the approach as much. That's great you are getting people stoked at how well the kite can fly in such light conditions, but the reality is it was more than 2-4 knots. Maybe it was that light during a lull on the water and that's why you dropped the kite in the water, but there was a steady breeze.
As for the gentleman with the 21 meter foil, he was inexperienced and could barely fly that kite in 8-10 mph on a different day.
I remember that day Chris Moor who is the manager of theKitty Hawk Kites store and probably your boss …. Are you Paulo the one who works and teaches at KHK on RRD!!!

In addition, at a recent visit to Cocoa Beach, Epic's owner claimed the ability to SUP-kite in:
In response, the following was posted by a knowledgeable local:Dimitri M wrote:3 to 6 knots

Despite the claimed performance in "2-4" or "3-6k", quite clearly, the Epic Infinity cannot perform on a SUP until >10mph (9k). This has been confirmed by reliable objective observers and wind speed measurements. It is interesting to note the hostile and personalised nature of the attacks by Epic
EPIC SLAMS BLADE
Not only does Epic stretch the truth about the Infinity, it also unfairly slams its competitors:
UKSurf wrote:Dimitri M wrote:The difference from the INFINITY V2 vs the FAT LADY is that the INFINITY v2 turns faster and has better pop. But the power is piratically the same after testing them.
Now the INFINITY V3 is something different.
Why did Momi design an inferior kite for Blade? I honestly think this claiming your kites are superior to everyone else's will only backfire. If it is better at one thing then it will be worse at something else, most people appreciate that kite design these days is about finely balanced trade-offs NOT one kite being better than another.
Light Wind Showdown
While the Epic Infinity V3 was shown to be INFERIOR to the Core 19m, a formal light-wind "showdown" amongst the biggest claimers (Flysurfer, Epic) and others (North, Core, Blade, Ozone, Slingshot, etc) would be one way to clear this up once and for all.
FAKE FORUM NAMES, ABUSE, & BONHOMIE
Epic's supporters admit to creating fake personas on this forum, replete with the same retarded spelling, grammar, and syntax. The fake personas push Epic products & abuse anyone who DARES to question their claims. These fake personas, e.g. Kiteus Maximus (below), personally attack and vilify, unless, of course, you agree to stop criticising Epic kites:
Kiteus Maximus wrote:Whatever dude. You created me. If you don't like me then stop creating me.
Of course, walking backwards with a kite is not a recognised way of testing its low-end, UNLESS you are making claims that it can fly in "2-4 knots". It would be EASY to test Epic's "2-4 knot" claim by putting up the Infinity in a school hall or similar & walking backwards at the standard walking velocity of 2.7 knots. The lies promoted by EPIC are even more appalling when they are couched in the fake bonhomie, oh so *HILARIOUS* pics of goats, and apparently friendly banter, not to mention the overt aggression and threatening behaviour of the "Kite2Heaven" persona.Kite2Heaven wrote:PMU - you really are stupid if you are resorting to walking backwards with a kite !!! … Otherwise "ALL" wind readings are BULLSHIT just like yourself !!
STOP THE BULLSHIT: RETURN THEIR KITES
There IS a simple way to put to rest ridiculous claims by Epic or any other kite company: BUY THEIR KITES. If they don't perform in 2-4 knots on a SUP or whatever - let alone below 7-8 knots (and they won't), then return them. A "class action" against these companies, perhaps using this forum as a meeting point, will force these companies to be more truthful.
Ignore the lies. Ignore the propaganda.
No kite can perform under 7-8 knots, let alone 2-4 knots.
