Trailing edge sanding tutorial (Donaldson trailing edge): • ExFabrica - Episode3: ...
Wing surface finish is done in steps with wet and dry sand paper, 360, 600, 1200, 2000 grit.
"-1 Degree" shim (need to 3D print) - it's what I use to make the tail wing flatter in relationship to the fuselage: axisfoils.com/products/axis-f...

Thank you for taking the time to make this helpful video.

[@scp8412]

Love it! keep those coming!

[@remyruff]

Good info, especially rounding the pressure side of trailing edge. Do you sand your masts?

[@SilverFoilSurfer]

Didn't find the need to sand the Cedrus mast, it has plastic-ish inserts at both edges, not sure is should be sanded.

[@dkschrei]

I also spray on a hydrophobic waterproofing compound after sanding. Its supposed to make the surface 100% waterproof and also protects from light scratching.

[@SilverFoilSurfer]

It probably gets washed away after a few sessions, unless it's some kind of paint-like stuff

[@rndlab2]

which one?

[@mm74forums7]

It is good idea for bottom surface. But I have doubts about the top one. Water should stick to it to create lift. Otherwise it may cause flow separation. Sure vacuum will try to prevent the separation. But still ...

[@scottseale]

Can you say which sanding grits you cycled through after the initial 360? Thanks

[@scottseale]

Sorry just read the info I asked for in your description.

[@gcammar]

That video you link from the Levitaz guy is the only one that says to sand the pressure side (which I call flat side). Everybody else (Armstrong, Alex Aguera of Gofoil, Fanatic, and others) say to sand the curved side. Which is kind of shocking, really. In my experience, I successfully tuned to silence a bunch of Armstrong wings by sanding the curved side. I failed to silence Axis wings that way though. Cheers.

[@SilverFoilSurfer]

To some extend, just by making the trailing edge thiner makes a noticeable difference, Funny indeed different brands recommend to sand different sides.

[@apricotscrub]

are you sharpening the trailing edge? Isnt a trade off of reducing safety in exchange for increasing performance?

[@SilverFoilSurfer]

Yes, you just don't make it razor sharp, just sharp enough and finishing with the rounded edges.

[@martinomovies]

Will doing this help get up on foil faster? Or is it mainly for glide?

[@SilverFoilSurfer]

It should make it a bit faster and glidier, yet to test (need some offshore-ish wind to try)

[@mikkgodfree3886]

Keen to hear about differences in performance post tune. Thanks

[@SilverFoilSurfer]

@@mikkgodfree3886 It's was clearly noticeable right after sanding it, now I can't even tell what's the difference :). More slippery/glidy for sure and it makes way less noise now.

[@roymassey1364]

Great great information !what size fuselage are you on?

[@waterbaby299]

That's the re sale value halved i imagine? I don't think i would have got rid of the graphics personally

[@SilverFoilSurfer]

Not really, it's performing better than the factory one for sure, technically the value should increase ;) but yeah, not everybody understands it.
