 nice !!

That PDF doesnt say ,that i could see , how to connect the sections together?

because they dont make them the way we are doing it?

i have to admit i didnt read the whole thing.

23 KW from a 15 foot radius blade is pretty awesome!

shame they couldnt do more testing ..

If you would switch to a lighter foam for the positive mold, you could use a hot wire.  With thoes, you can pop out sections in less than a minute.  Cutting the wood sections was by far the hardest part of the fab for me, and I had the airfoils printed on paper and glued to the wood.

i decided to make a small one to test everything out , and i must say when i tested it in front of a fan , it was pretty impressive, for its size..

i couldnt figure how to get the best pic of this so most of them are of the inside , this shows the angle the best..
