We finally got to a Version 1 of the foil design / optimisation program that is fairly clean and easy to use. Give it a download and try at the below link. Wing_Bot V1.0 https://drive.google.com/file/d/1Pq9JYPHjYMO57p21PuzyGYz9yLl3f2RB/view?usp=sharing Happy playing / designing. We've got more idea...
Thanks for the reply. I think they use wing washout on aircraft in part to reduce wing tip flutter. I think it might reduce induced drag a bit too. I will give a shot on fixing trailing edge. It's finished mostly like my other wings, but those are quite quiet. On my foils I have my foot close to the...
Nice addition to the software. Now things will be even more accurate. Do you think wing washout is worth considering on our foils? Managed to try my alu setup lately. Surprisingly it performed well straight away. I had the stab set at -1 degree and it felt good like that. The wing was stable in pitc...
Hei guys, the spring came and brought some motivation
Front wing rg14a147, span 750, area 750
Stab naca0008, span 460, area 280
Looks fast, and dangerous :/
Might have a chance to try it tomorrow

Looks good PrfctChaos I have little motivation at the moment since it's cold, get's dark early, and 15cm ice on the fjord by house.
Thanks for the input on the stabs, looks like I'll give the symmetrical profile a go with the next stab
It was an interesting read on Moth @PrfctChaos. The stab has almost as much section drag as the main wing. I'm using inverted stab profile ( I think H105), but on Moth looks like it's non-inverted. And I think you said you use symmetrical profiles. The way I understand is : noniverted good on high A...
Thanks a lot for help. It does seem that the difference is very small between the airfoils on paper ( few hundred grams to a kilo). I wonder what would be total drag of a complete hydrofoil at maybe 30-40 kmh? Maybe the selection of 'airfoil' is much less critical than wing shape, wing tips, shape o...
