LOOKING FOR SIMPLE AIRFOIL SHAPED PLASTIC!
(OP)
I am searching for any plastic extruder that might be producing an airfoil shape (as in autogiro rotors---flat on bottom). My concerns are for model type autogiros and would have a width of 1 inch to 4 inches.

Actually my search is for any kind of material that just might be being mass produced (and therefore much more likely to be reasonably priced) in something close to an airfoil shape. I guess I have my own modus operandi which has worked for me all my life and no matter what the real engineers say I am going to stick with it.

You are not likely to find someone who will see you as a competitor allowing you to use his tools. Luckly the price of a die for something like this would only be about $300. I would suggest a fiberglass pultrusion like they make kids bike flag antenas out of. Finished cost of the product would be about $2.00 per pound in reasonable quanities.

Your note is much appreciated and I assure you no bad mouthing was intended. Over the many years I have been around I have simply developed my own way of doing things and have had enough success to not particularly want to change.
I have been to many web sites where model rotor blades are offered and in every instance they are very expensive and one of the reasons for that is that they all incorporate the 25 percent balance rule and with my design that is simply not needed and I feel that if I could extrude the right kind of plastic I could get a useable rotorblade at a very reasonable price and your note seemed to indicate that. But I must admit that until I do it I really will not know if it will work. Thanks again for your suggestions and I will look into those forums you mentioned.

You can get a provisional patent for <$400.- ,good
for one year. You don't need lawyer but you have
to describe it as completelly as possible. Within
one year you MUST file or lose it.
