Nice flights. It didn't look too bad for back pressure considering you/most people like C on the 84 . I know Wyatt Miller says it needs a bit too much back foot for wizard boards but that did not look like the case for you. Looking forward to your reveiw with position C on the 99

Think I might have bit more of a lead foot than Wyatt! He's classic surfer physique, I'm more of classic Dad bod ;)
our forecast looks dismal this weekend, Monday might be the soonest before I can try C and the 48 rear.
Interesting that Wyatt insisted that I-99 would work only on Levitator or Freestyle with tracks. Looks like you proved him wrong. I just got mine and comparing it to I-84 it is hard to say that the center of lift is that much different.
I-84 has a chord of 304 mm vs. I-99,s 296 mm
I drilled an extra hole in the fuse to move the wing/fuse forward 50 mm more from position "C". I have not tested it yet because I had surgery on my face yesterday, and the wind was over 20 kn anyway.
Just tempted to set my record in lightwindedness

It is a bit strange why we have all heard different "why it won't work scenarios"?
The first day I was on the 84/42 B set up and flying, as the sun went down, I bolted on the 99 and took off immediately in 10/11mph. It just kept chugging along with a bit of pumping.
Second day, I would've rigged a 7.8 but decided to test it again on a 5.8 again in around 10mph or less and had 2 hours of foiling.
Easy as!

Did you use a hand drill, or a proper drill press to make position "D" hole, that's a clean piece of engineering.
I used a drill press with 8 mm drill bit and 16 mm countersink bit. Easier and cheaper than to buy a Levitator or install a track system.
I have a Wizard 125 and am tempted to purchase the 99 and use it in the "B" or "C " position. I'll bet it will work with most boards in the "C" position. I'm 45 pounds lighter than CorAS so if "B" position works for him it shouldn't be a problem for me. The question will be -- in just how low a wind speed will I be able to foil?
I used the i99 on my Fanatic Falcon LW a few weeks back. "C" position.... 8.0 Ezzy Cheetah for power. Wind was 8-12mph max. I thought it worked quite well, but I'm new at this.
I was able to get some long flights in the light breeze. I was more amazed at how well it stayed on foil in the lulls.

Monday I tested their 99 in C with the 48 rear and it was incredible. Wind was a different direction so we had a small swell to pump up on but either B or C will work. at my weight, I do have to put a lot of energy into the pumping but I'm confident with something like a 6.4 or 7.0 with the 99 wing I could foil up in 8-9mph and glide in 6-7mph (depending on wind direction and water conditions)
the 99 wing allows you to pump the board pretty aggressively as well.

When do you feel i99 is too much to handle in terms of wind conditions?
CoreAs and sl55,
Thank you for your responses in the comment sections of your Youtube videos. I am using the I84 foil in the C position, the 48cm stabilizer and the long 78cm fuse per your recommendations, on a Wizard 150. I have had a great deal of success in my first six sessions. Thank you again, Brant
PS: And in the spring I might try the I99 foil.

Much like the i84 wing, you can foil the i99 in pretty strong winds, they both will "limit out" at their top speed.
My foiling mate was out in 20+ on his last night and he was doing pretty good but found gybing a bit difficult, think we both concur that the 99 sweet spot is 6-15mph.
I have been wing surfing and use the i99 wing for that also. Wing surfing is pretty slow speeds anyways, I just need the bigger wing to pump up, then cruise from there

Its funny I could not make the 48cm stabilizer work with the long fuselage. (48 stabilizer positioned underneath the fuselage). Maybe I need to give it another go, it was quite a while ago.

What the 48cm stabilizer with the I84 foil and the 78cm long fuse brought to me was a noticeable increase in pitch stability versus the 42cm stabilizer. With increased pitch stability there was more time up on the foil. With more time up on the foil, the learning curve is accelerated. And an accelerated learning curve gives greater satisfaction. Hope this helps!

Yeah the pitch stability with the short fuse made gybing near impossible, so I ditched that and went back to long fuse small stabilizer. Maybe I will try the 48cm stabilizer on the long fuse with 84 again.
Last Saturday wind was crappy SE side-offshore and I decided it was time to test Infinity 99. After few nights below freezing the water got really cold and I took a short 71 cm mast off of my wife's board. It saves me an extra 100 meters of wading. The wing was in modified position "D" as I reported earlier. Because of the short mast and the wing so much forward, behavior was different. The board was more squirrelly than 84 on a long mast. I could not pump the board pushing on the back foot as much, and the tail was drifting wide if I sheeted in too energetically. But I think I gained a knot or two in the bottom end. The balance was less back footed than 84 in position "C". Would be interesting to test 99 on a long mast in C and D position. Next season I will. Crashed at the end loosing the foil. My fault - used wrong bolts between the Tuttle head and the mast.
Wow good save on the foil and I loved the self rescue where you placed the foil mast in the rear foot straps and used the wing as a fin! Did you use the 42cm stabilizer as a matter of convenience or was there some thinking behind it use?

I never thought of using anything else. You mean 48? I thought they are for short fuselage for SUP.
Chicken straps are handy
Moral of the story: use proper bolts. The short ones came in a set I bought from SS thinking it is a full set. They sell the long ones separately. Turns out the short ones are for position "A".
Wow nice save getting to that foil! I too think putting the mast through the rear straps was clever.

48 cm stabilizer is used with the long fuselage and it should be put in in wings are downward.

I originally bought the H2 wing with the blue 42 cm stabilizer. The H2 wing was about 1000cm sq and the 42 cm stab about 300 cm sq. When I upgraded to the I 84 wing with about 2000 cm sq. I first used the 42cm stab, then moved to the 48cm stab with about 500 cm sq. It improved the pitch stability. This was all done on a long 78cm fuse.

thedoor and lakeeffect,
can you guys measure the angle of attack of both stabs in relation to the fuse ?
Thedoor,
what exactly do you mean when you say it didn't work for you? What was the problem? Too much drag?

Thedoor,

The angle of incidence at the root roughly measured in O degrees. as you move toward the tips the angle goes slightly negative. This idea comes from airplane design. When a airplane wing stalls you want it to stall at the root first, not the tip. This keeps things in control.
The above is a U-2 spy plane. Notice the high incidence angle at the root and the lower angle at the tip. Model airplane guys call this wash out. They also do this on propellers.
Good save SL55, think you're the 3rd or 4th person I've read that accidently used the short bolts. My foiling bud luckily had a foil leash the very first time he went out and it saved him losing the whole lot.
On the Wizard 125
I have foiled the 99 with the 42 rear in B, works very well (long fuse).
I have foiled the 99 with the 48 rear in C, works very well (long fuse) a hair quicker to foil up (but not as slippery in the turns as the 42 rear).
I have foiled the 84 with 48 in B of the short fuselage and it did not work well at all, couldn't gybe with it, way to pitchy.
I am currently using the 99/48 in B on the short fuse for wing surfing only. The short fuse allows me to pump the board and get my weight right over the front wing.
what exactly do you mean when you say it didn't work for you? What was the problem? Too much drag?
Yeah I couldn't get it too lift. So I moved to a small fuse and it worked fine but gybing was super hard. So I went back to the long fuse and 42 cm stab. Next light wind day I will try the 84 and 48 and long fuse.
sl55, I didn't answer your question fully. The 48 rear stabilizer had about a 2 degree negative angle of incidence with reference to the fuse. Please view these number with skepticism. They were done with a wooden straight edge, a ruler and a little trigonometry.
Reminder that a lot of cell phones have the capability to be a level with the proper app. I have a cheapo Lenovo Android that has the capability. Just don't drop your cell phone on your board. They accelerate quite a bit in the 85-90cm until they get to the board invariably corner first.
I like the measurement video. The I84 foil has about a 300mm chord thus a 6 inch caliper won't do it. They have a 12 in caliper on ebay for 26.99 and the Wixey angle gauge is 26.99 so it's reasonable to buy the measuring equipment. Or I could go to a good restaurant and order two entrees!
Here's a video of Wyatt Miller explaining when to use the 48 cm. stabilizer rather than the 42 cm. one. Apparently the 48 is used for pumping the board (downwind sup or with a wind wing).
