I wanted to give an update on this.

When I drilled out my fuse and wings over to M8 I could not find the long middle bolt in A4 ss. I figured because the diameter was bigger I could get away with A2 bolts from McMaster. I promptly bent them!

Bruce and the folks at Sailworks have been very patient and supportive through all this. I really appreciate their dedication to customer service! He sent me link to purchase Titanium fasteners.

The new bolts have been flawless! They were not all that expensive at around $10 a piece. Let's just say that I have tested them under full load repeatedly now and they are solid! They also come with a colored coating so I choose the long bolt in a different color to help pick it out.

Long story short, I now charge with confidence on the amazing Moses 1100!

I mountain bike and this long thread reminds me of some silly forum threads where people ask about using aluminum bolts to secure disc rotors (mamma!), or titanium bolts bought from e-bay on high stress areas such as a seat collar or bar stems . You can do that, but don't complain if they fail ... and don't be so surprised when bolts up to manufacturer specs don't

did you drill and tap or also install helicoils? Seems like helicoil installation isn't much harder and would ultimately have longevity benefits, or is there a downside to helicoils?

Thanks for this post guys. My w1100 gaving same issue with m6 bolts, busted one bolt and wing has worked loose on several occasions with bolts bent slightly. I 80kg and have been winging and sup foiling on wing, it does perform well unfortunate this issue! Just pur hased some titanium m6 bolts before reading this, will try taping out to m8 if they still problematic, helicoils crappy idea i think as corrosion will be issue. Cheers again for info from moses, foiling is such a new sport we can only expect these issues from all manufacturers, i have kited with full carbon one piece quality set ups and they break too!

I using 710 standard fuse with m6 threads, anyone know the difference with the 710hs fuse apart from m8 threads?

the differences are:- 8 hole - it is more strength- the degree of incidence of the stabilizer is - 1.5 degrees, while on the old FW900 it was -2.3 degrees

It took some time to figure this out, but the convention for naming stab shims refers to the effect on lift of the front wing. A shim labeled +1 actually increases the stab down angle by 1 degree. This has the effect of increasing the angle of attack of the front wing increasing the lift.

I typically decrease the stab down angle because I want to control the lift with my back foot, rather than it controlling me. For example, with the Moses 950 wing on the newer 900 fuselage (M6 holes), I shim with -0.5 deg. This makes it really easy to control and ride. (Many riders shim this with +1.0 deg, but this makes it too front foot heavy for my liking.)

so the new HS899 needs less shims than the old 900 to provide the same lift?

The newer new fuse, the 899, has M8 holes. The sorta new fuse, the 900, has M6 holes. Mine is the 900, which I got in August. The 950 wing has M8 holes, but includes stainless cones to mount M6 screws through.

I think it's the other way around. The HS899(-1.5) is angled down 1 deg less then the old 900 at -2.3. So you need a +1 shim to make it like the old 900 with no shim. I think you had both fuses so wounder if the difference is very noticeable?

Moses couldn't make it any simpler - three 900mm fuses. They also had to change the company name.

yeah and two different mast to fuselage connections kite/surf and wind

They do have the "wide range of wings" pre-requisite well covered though

segler said..
I like everything about my Moses/SAB stuff except the mast to fuse connection. Two bolts. The front bolt loosens from front wing lift, and you have to keep tightening it. A friend of mine even lost his front bolt completely until we told him about keeping it re-tightened.

Assemble, foil 20 minutes, re-tighten, foil 20 minutes, re-tighten. It will stay tight from now on. Since I foil in fresh water, I just tighten it this way and never disassemble.

This is what SAB told me regarding the 900 HS. You can figure out what they mean.
