at the moment my kai is nice and I'm thinking about modifying the maliko but soon I will have the opportunity to test the 18W and I cannot wait to see the differences 8)

Someone with the magical 18W tail take some pictures and post them here, or in the GF 1.5 thread.. Hard to find pics anywhere.

I am looking for a side shot to identify the chord height etc. It looks stupid simple. 18 long. pretty flat. Maybe a small amount of airfoil on top.

I am going to make an 18W out of nature. "I dont need no stinking pedestal maing!"

I thought about getting someone to hack my Maliko, cut the wings off and join them together and set flat at neutral level at the top of the original spigot tail.

The report on the GL18N compared to the Kai on the 1st test session (in 2-3' mush) was just an "eh, not so much".

Going to shim the rear screw to try to get a little more lift, and/or possibly move the whole foil forward just a just. But on said first test, no matter how hard I tried to push it, I never could get it over 12.4 mph (almost like it had a governor on it), when with the Kai, 12-15 mph was a no brainer on it depending on what I was trying to do on the wave.

Heading out for test session number two....but after seeing this....

....Austin on what appears to be a GL front w/ the Kai tail in this video...

...I'm wondering if the Kai stab isn't the go to setup to be on now.

Sano, interesting on the your slow speed comment regarding the GL18N. To me it looks huge. Like too big. I would imagine that comes with drag. I do like the flatness.

Cut some off of each end of the GL18N, send pics and report back please ;)
Thanks in advance

GL 18W are:
460mm wide, 70mm cord at the center and 7mm thick.

Interesting comments SanoSlatchSup about the kai versus the 18N tails. I will test this weekend and see the difference between 18W and kai and maliko with GL210 front wing.

Very interesting!  Looks like the only difference between 18W and 18N are the chord (70mm vs. 60mm).  Same span and thickness. I had assumed that the Wide vs. Narrow referred to the span.

the word is they will no longer stock the 18N (lucky for some maybe) and for now only the 18W is available.

Having been able to see the 18N and 18W side-by-side, it was easy to see that were the same length, so I assumed that "18" was 18" in length/span...and the "W" & "N" were the chord/width.

What I also found interesting (and unexpected), is that the GL 180 and 210 have the same thing going...same length/span, and the only real difference is the chord/width.

Heard this as well from an industry insider.

As to the Kai tail being the go to setup now:

For radical bank angles in waves, this would make sense. The 18W has breached on me in places the (upside down) Bonanza tail wouldn't have.

...Or maybe these guys just grab whatever is handy

I have to disagree with the KAI tail preference.  Austin is riding the Kai but watch Dave at the end of this video.  Dave is on the GL tail.

The GL tail with the GL wing is FAST.  Really fast.  The lower profile FLAT wing offers NO Yaw Stabilization.  The vertical component of the KAI tail acts like a rudder and will NOT turn as well.

I rode the KAI tail all summer with a big Mailiko 200 wing and loved it.  I would NOT go back to the Big Blue Maliko tailwing. 

However when I switched to the GL wing "My god is that board powered you're going that fast on nothing."  I say again watch Dave Kalama at the end of this video.  Hair on FIRE with a nothing wave.

I will be sad if they stop selling the 18 Narrow tail.  I almost bought another one to CUT it down further.

My take is that it has slightly MORE downforce at speed than the KAI tail BUT it is faster.  The KAI tail also introduced a bizzare buffeting.  It was vibrating but NOT humming when pushed hard at speed.

Look at the lines.
