Hi Clay!  Long time no see buddy!  I gotta come winging with you guys sometime!

I did not weight it, but it's so light it's essentially zero weight to me.  I can't tell it's there under me unless I look  ;D

I keep the foil on it at all times, but I'll weight it with the Lift setup next time I get it down to play to get an idea.  I'm thinking somewhere around 8-10lbs for the board only???

supfoo, haven't tried the fliptip, I was told the flat was faster?  Might cut it down though as something to try for more speed and maybe some fillet work between the rear wing and pedestal to stop it occasionally stalling.

Yea, I find it hard to get a good variety of pics of new products at times, same with this product, so I go out of my way to get some good ones at all angles for anyone in the same position.

I came off a 6'5 Flying V for winging that I started SUP foiling on when they first came out.  I will add more review info once I get more time on it.  I've only had 3 sessions so far.

I've gotten the GL140 into the upper 20mph range.  Haven't ridden the Lift 120HA yet, hoping for 30's.

I'm 180lbs, not too hard to ride this board, as long as powered up.  Once flying it's epic!

I'll take the 180 if you still have it.

Interesting, I just think about windsurfing fins.  if you have a nick in the trailing edge or any gaps around the fin it tends to spin out/stall/cavitate a lot easier.  Who knows.  I thought about melting hot wax into the gaps as a temporary test, but I bet the forces involved would rip it right out!

Damn, I wonder what's holding my back.  Must have something to do with that rumbling I get which causes loss of lift and speed.  I did notice that the fuselage fitment to the wing is not great, there is almost a 1/4" lip going from the fuse to the front wing (pic attached).  The lip is also at the trailing edge of the main wing, so maybe it's creating a cavitation and spreading to the wing causing a stall.  I think I read somewhere someone faired their wing to the fuse.  Maybe I need to try and do something like this.  The wing did feel faster, but it did not pump well and it did not take off well, and according to GPS it was not a lot faster, just 1-2mph.  There must be something wrong with mine.  I didn't think much about this, but the top surface of the front wing has an indented area.  It's not very deep, but in the light you can see where there is a flaw.

Beasho, what top speeds have you seen on the 210?  If mine is significantly slower, then that kind of confirms there's an issue with my setup.

I kept the washers out, just didn't crank down on the bolts crazy hard to be safe.  Hearing the whine doesn't bug me, but does make me think something is not optimal.  I guess I can do the trailing edge sanding trick like in the videos if I want it to go away.

I'm thinking the GL240 might be closer to the performance range of the M200 than the GL210 let alone the GL180.  Smaller is always faster, but slow speed performance suffers.  I didn't realize how much I rely on the M200's slow speed take off ability to catch waves.  The 210 just didn't have it at all.

I will ride the GL for a while and then switch back to the M200 to get a good back to back comparison.  Can't judge anything 100% in one session.  It wasn't the greatest conditions today for testing.  On a good day I might get a different experience with some of these things.  Very interesting riding something totally different!

I was desperate and went out this afternoon to give it a try.  Bumpy, and big.  6.6@12 but felt a lot more like 7-8@13-14.  1.5 OH ++

My watch recorded it and I compared to a similar session with the M200.  Looks like it's about 1-2mph faster on the top end, and about .2mph faster on average... but I will need more sessions to see if it was just a bad day for the 210.

At top speed I would get a rumbling like bad flow over a wing and the top end speed/lift seemed to be held back, maybe flutter?  It also would make a very high pitch whine at top speed.  I wonder if the rear wing is getting caught in the wake of the front wing, hmm.

Some observations compared to the M200 while it's fresh in my head:

-Take offs, NO lift at less than 5mph, nothing.  I missed 80% of the waves I normally could have caught with the M200.  I just could not get any pump out of it at the start at all.  I was back to paddling a 6' barge into big waves, which is,,, stressful  ;)   Half the time I resorted to getting going in white water to avoid the super late drops in the big waves.  Definitely about 80% harder to catch waves vs the M200.

-Low and mid speed have good pitch sensitivity, very controllable.  Once it finally gets flying its very easy to control pitch.  High speed is very sensitive, bordering unstable.  I think maybe the 2deg elevator pitch is too much for top speeds... I might use washers to get closer to 0/0 decalage (both wings at neutral incidence).  This might also be why I seem to maybe be high speed stalling the rear wing at top speeds.

-Turning, wow, yea, I don't even know how to describe it, seemed like it was not happy to go in a straight line... like the wings wanted to swap ends via yaw axis... reminds me of a mid engine car in the rain, losing traction.  Initiating a turn was a bit more lazy than the M200, but once leaned over the pitch was super active for the rest of the carve.  I have to say, even in the big waves and top speeds, I did not breach even once, which is amazing.  I wonder if the tail couldn't possibly use a small vertical stabilizer or something.  It's a bit loose going straight.

-Speed, yep, it's definitely faster, but it's also a lot smaller, both outline and volume (I noticed my board didn't float me as well, lol!).  It's not scary fast, it just feels a little slippery.  I seemed to get up to top speed on it and it didn't want to go any faster.  GPS says it tops out around 20.x mph... at least in todays conditions.  My M200 has been up to 19.x mph.

-Paddling efficiency, yea I like that, definitely noticeable.  I think the M200 is basically trying to fly when you're paddling out, creating a lot of drag.  The 210 definitely paddles faster... as fast as a 6' barge can go anyway.

-Pumping back out.  The first time I tried I got a good run at it and made it half way back out, but after that nada, the rear wing would stall out on me and plop me back in the water, frustrating.  So may exits I could have pumped back out with the M200 and I was just stalling out  on the 210... except for that one magic time.  I'm very surprised by this given what others have said.  I can't help but think that the rear wing could use more thickness so it didn't stall so much before the front wing... it needs better slow speed performance to match the front.  I did notice I had to get my back foot much father back to get any kind of good pumping action, much farther back, like 2-3 foot widths.

Overall, I'm not super impressed for this first session and with how it's tuned.  It seems just like trade offs, no real super advantage overall.  The smaller wings I learned on behaved very similar, much less low speed lift, but a little higher top end speed, and ability to glide out a bit more in the flat if you have the speed.

Still, new stuff is fun, I'm looking forward to putting more time on it to see what it can do, but it's not a replacement for the M200, totally different animal IMO.

Giving the GL a shot.  Checked the decalage and without washers, it's 2deg pitch UP.  What are you guys all running for washers?  I see a pretty big (1/8" before cranking down bolts) gap between the pedestal and the rear wing, should I run both washers if I want the incidence the same as no washers to fill the gap?  Seems like a good idea so I don't split the wing lengthwise.

I got the 210 and the surface area looks about the same as the IWA 170.  I've been riding the M200 all year, I wonder if I will miss the lift?  Anyone trying the 240 in the waves?  I'm 180# but generally ride smaller weaker waves (head high or less) but not always.

Will take a first ride soon!

Nice one Clay!  Out at the pit eh?  I got a 2700ft ride out there last year following the channel into the bay.

Haven't had any leaks on my custom box install the way it was done:  https://www.standupzone.com/forum/index.php/topic,33404.0.html

Usually the last piece to go in is the layer that covers over the box/insert and WELL into the surrounding skin.  Then you cut/drill back out the box/insert holes.  As long as the bond is good between that layer and the board skin it should be pretty waterproof.  I'd rough up the plastic of the box/insert really really coarse so it gets the best possible mechanical bond if it's not an epoxy friendly plastic.  You have to have a strategy to keep the epoxy out of the box/holes though.. wax or tape or something.  Acetone will remove any wax that got on bonding surfaces.

Foil SUP / Re: Tuttle Plate Adapter Aluminum vs Carbon Weight
« on: March 06, 2019, 09:56:09 PM »
I don't know the weight of the GoFoil carbon adapter, but here is some info about a carbon one I made, the Groove carbon adapter, and the Aluminum one: 

My custom carbon adapter was 610g
Aluminum was 691g
Groove carbon was 518g

https://www.standupzone.com/forum/index.php/topic,33335.msg377279.html#msg377279

My advice, forget about 100-200g difference, you'll never notice it.  That said, it's a lot easier to get a foil into/out-of the carbon adapters than the aluminum one with it's CNC micro steps inside, not sure that's worth +$100-200

Foil SUP / Re: GoFoil 29" mast upgrade
« on: March 06, 2019, 09:38:45 PM »
I got lucky and my board has dual boxes, so I'm now using the tuttle for the first time ever foiling.  I was running my track about in the middle with the short mast+adapter, so no change in stance was needed, however, I can imagine some people missing the adjustability.  I can tell you it was a whole lot easier adjusting the pitch of the foil by shimming the tuttle box rather than creating a shim for the track box (which I did when I was using an adaptor with the 24.5" mast).  Sure would be nice if they beefed up the 24.5" mast, my was cracked and loose after less than a dozen sessions.  Unless they can make more money beefing it up I doubt it'll ever happen, so probably never.  :(

I'm curious, are you guys using the 29.5" in a Tuttle, or throwing it in an adapter, and running it at 32"....and any idea why GF choose to go an inch different with the Tuttle mount, and adapter mount instead making them both 29 or 29.5"?

I like the idea of going 29.5", but don't like the automatic limits of placement that comes with it in a Tuttle box, and would like to have more than just the 1.5" gain I'd get with the 28.5" adapter version from what I have with the 24" Tuttle in an adapter, and the 27" mounted that I'm running now.

The 29.5 in an adapter making it 32.5" seems just a little too long, especially with the shallows that we're stuck with a lot of the time with the tides, and reef settings we have at Sano. IOWs, I've got a banged up enough wing with the 27" mast, and can only imagine what it'd look like if it were another 5.5" longer. :o

Or maybe I'm just overthinking it all...as I have a tendency to do.  :-[ :)
