SanO--thanks for the pricing info.  A bit more expensive than I was projecting too at least for the front wing.  You know that we are foil addicts when we are pushing for any info including pricing! :D

Steamroller/Bill--thanks for the ride reports and pictures.  The wings and new tail sound like an amazing upgrade for downwinding and possibly surf!

Jeremy Riggs mentioned in a post on facebook that he needed to change his stance--moving back quite a bit to get the new GL wing he was using to fly. I'm thinking that might be what I was doing wrong yesterday. I didn't feel much lift at all. I was putting my front foot in the strap on port tacks and didn't get even a pop-up despite some really impressive non-foiling speed. On the starboard tacks, I can't get my foot in the strap and probably was standing further back when it popped up. I shouldn't expect new stuff to work like the old stuff.

Steam and anyone else using these, have you changed your stance?

I donít have Facebook but watch all of Jeremyís videos on Instagram. His rear foot is noticeably further back on the board now in the latest video (almost off the board) than in vide of a year ago when riding the 200. Could it be the newer High aspect wings ride better with more weight on rear foot?
Tried posting screenshots but couldnít do it.  :-\

PB, since I've not tried (or even seen) a GL yet, this goes more to just the differences in foot or mast/wing placement of the smaller vs. larger wings to get them to fly appropriately.

When I was finally able to really test the Kai setup in some decent surf, I do anything different wrt to foot and/or place mast placement. But when it got smaller a few days later, and since I really enjoyed the feel of the Kai setup, I left it on, and just wanted to see exactly how small of stuff I could get it to work in.

I found that even at about 190 lbs on a lower glide 6'x29" board, that I was able to get it to work OK in waist/belly high stuff w/o changing anything up, and while I missed a couple waves that I'd have normal got with the Iwa setup, the looseness, and nimbleness of the Kai was just more fun when I kept the gas pedal pressed on it...although a little more work than usual in the smaller stuff.

But since "OK" is never what I'm looking for, on the beach I was chatting with probably the best SUP foiler in our area, and we kind of came to the conclusion that moving the mast/wing forward for the smaller wing would be better than leaving it where it normally sits, and trying to reposition ourselves/feet further back on the board.

The thought/theory was that since we're already at the rear of our boards (he rides a 6-footer also), that any further back would really effect the ride attitude of the board on foil in the air, and moving the mast/wing forward under the board while leaving our straps/feet in the same place, would basically do the same thing foil position to the feet for getting the board out of the water, but once in the air
we'd still be "centered" on the to fly "level" as we'd normally do.

Any thoughts on that, or how that may or may not apply to the GL wings as well? Thanks.

Nothing magic here.  Center of lift for the wing is 1/4 Chord.  25% of the way from the leading to trailing edge of the FRONT wing.

When I took the tail OFF the Maliko 200 last year my front foot position required moving BACK 8" from the normal spot.  What this showed was how much DOWN force was being imparted by the tail wing.  My Center of Gravity moved back 4".  1/3 ft X 180 lbs = 60 foot pounds of force.

If these Tail wings have NO lift at Zero Degrees angle of Attack, and if the Chord of these wings is 2" less than the Maliko 200 (Average ~ 8") then you have to move CG back another 1" for a total 5" CG shift.  Alternately front foot goes back 10".  Wow!  That does seem like a lot.

All of this makes me want to add tracks to little Fugly, but I'm not going to. I have plenty of room to move back.

I'm pretty sure Jeremy's board has a Tuttle.

Hahaha, well I guess that's a pretty good reason to move your feet and not the foil. ;D

Go for it PB, you can never have enough tracks on a board....

To confuse matters more on those debating between GL180 and GL210, here is the GL240 in action in the surf...

I used a GL240 today. Astonishing glide. Tomorrow should be even better.

Beasho, I'm easily confused by science  :o :) but if the Maliko tail's shape (wings down) creates "much DOWN force", would turning it over, and installing it upside down create "much UP force" to create more lift?

With stabilizers everything is "backward", so no.  Down force increases angle of attack directing the foil up and out of the water.  Up force decreases angle of attack and send the foil into a nose dive.

I'm glad to see goifoil adding the option to shim the stabilizer, not being able to would be a deal breaker for me.
Aloha, I welcome and appreciate all responses of positivity and good feeling.

So Gofoil found it.

The holy Grail of foiling.

I just got the Iwa M200 and M280 , have to get rid of them now and lose a lot of money, or should I wait out the storm?
