I am planning on machining an adaptor plate for a modified Neil Pryde Glide foil fuse to allow me to fit Axis Foil wings. I could do with some dimensions from an Axis foil if any one can help? I just need the mast chord and the distance from the front of the mast to the front of the fuse mounting stub. The dimensions of the mounting stub would also be helpful. Thanks in advance

That is an interesting project.
I have a Neil Pryde Glide with a Large and Medium wing and am tired of waiting for the XL wing.
I am also jealous of all the mast size Axis offers, a 60 cm for shallow conditions and a 75 or 90 for windsurf foiling and wind wing...

So I was thinking of getting an Axis....but I already overspent on foil equipment.

Yes the same as my reasoning for the project. Just need a helpful person with an Axis foil now.

Have managed to track down a local foiler with an Axis rig so now sorted. Cheers

Hi sweats,
good plan to make your own measurements, I made some pics for you, but cause deviation by the lens they are useless for precision work.
Please keep posting your project.

PS: Don't forget to measure the Axis Frontwing AOA (Angle of Attack) and the AOA of the Stabilizer in relation with the LE or TE of the mast.

Hi Paddlezz.
Thanks for the pics. Hope to see an Axis foil in the flesh next week and take the dims I need. One of my queries was the angle of attack? From the pictures I had seen it looked like the mounting stub was perpendicular to the mast but from your pics it looks like there is a small angle. I will take my engineers protractor with me to measure it. Will keep you posted.

Normally, the fuselage axis has to be at 0 degrees, the mast at 90 degrees. Determining the fuselage axis is very difficult, so it is best to take the mast axis as 90 degrees. So the measurement is then transferable and reproducible to other systems.
The AOA from the foil is best measured from the (extended) maximal cord line (or a parallel line of it) between LE and TE and the mast, the measured value in degrees minus 90.
To capture the maximum cord line, you might have use 2 equally thick block materials with 2 equally placed notches to put them on the LE and the TE of the foils. Lay a stiff ruler on the blocks to make the measurement.

Thanks for the info. I have just been looking at my NP mast/fuse and the wing mounting surface is at 90 deg to the mast. This is the angle I want to measure on the Axis foil. I am hoping it is also 90 deg. Hope that makes sense. Not certain what you mean by LE or TE?
With regards the stab, I am planning on using the NP stab initially and shiming it if needed. I hope the project will work out. I have invested in a spare NP fuse but not yet bought an Axis wing. The main reasoning behind the project is that I would like to try the 1000S wing without having to buy a whole new setup.

Thanks Paddlezz. Think I have a lot to learn

Nice artistic work, It looks strong enough, if you re seal it with some varnish you can give it a GO now.

PS: Regarding using the NP stab, you can figure out with "try and error", spend a lot of time/nerves
or you re make measurements to avoid some bigger issues.
It does not seem wise to me to mix foils of different brands without knowing the AOA values.
Anyway, the AOA of each stabilizer is tuned to the own Frontfoil, or vice versa.

My expectations are not that high but have had fun making it. A friend is going to vacuum bag it for me but it is pretty solid as it is.

If you ask me, but you do not , I would first test it and then invest in more work and expensive composite material.
Especially if you still can make some correction on that wood model if necessary.

A good idea. I will give it some thought.

Hi sweats,

Looks awesome, have you any pictures of the bottom of the foil? Could you please share your measurements as length thickness and how wide you have yours?

I will give it a go and will do a similar HD design. Sure is a guessing game but I guess the angle of the foil could possibly be done with some thin shim to get the fine adjustment done.

If it works out well enough I could purchase the real GoFoil or Signature Albatross. Just want to test if this HD could be something for me before committing to the real thing.

Cheers
Anders

Hi anders
Wingspan 98cm, chord 16cm, thickness 26mm, aero profile GOE648, angle of attack 2 deg. Laminated up over a former to produce the anhedral using 2mm exterior ply. I have routed in a 5mm thick carbon plate on the undersurface of the wing to reinforce the mount to the fuse. I have tried to induce some wing washout in the laminating process but uncertain how this will work. I have looked at lots of pics of the new GL wings but it is all guess work. As more pics have come out, they look thinner and with less anhedral than mine. Would love to see one in the flesh. If you had one to work from I'm sure you could do a reasonable job. This is the first wing I have tried shaping and have really enjoyed the process. Maybe there will be a mark 2. I am just reinforcing the socket mount with the fuse and the undersurface of the wing with carbon and I hope to give it a go before final glassing. I will take a few more pics and pm you.

Quality work that. Be interested to hear how it works.

Thanks! Looks just mint, not sure I dare to post mine here
You might get a message from Gofoil to join their development team the way yours look.

Great to have your info, hope I can do as good as yours. Will glue mine plywood up soon. Should be fun to shape.

Cheers

Anders

Does anyone have the lengths of the fuselages? Interested to see the differences between ultra short, short and standard.

According to the Axis website they are 62.5 , 68.5 and 76.5 cm.
I have the standard with the 44 stabilizer and it is indeed 76.5 cm.

I will probably get the short fuselage with the 40 stabilizer later this year after some practice...
