a) personally I'd like to know a bit more about you, care to beef up your profile?
(Might help to assess what calibre of info we can throw at you...;-)
thanks for this wealth of information you share here, I'll surely file this one and try to take it in slowly. If you intend to build a replica of the wooden blades it might be worth having a look at these threads from 07/08 2009
Forget to say thanks for those great links. Wonderful to see the Germans restoring there great aviation machinery from the war. There were some very clever designers around then. I do marvel at how clever and innovative they were then. The new FA-330 is a beautiful job. They used fabric on the blades with a large cord. Hafners blades are solid oak spars and covered with plywood with a very clever lead cup in the end for balancing and a smart brass
poppa leading edge at the tip for balance also.
Interest in this technique has been renewed with the availability of small autopilots for UAVs
(But for cargo drop only, no one volunteered for manned beta tests so far...;-)
