Ducted Propeller

I'm trying to figure out why the first ducted propeller I build was so surpisingly good, I will provide photos of the first made as soon as I find time and a digital camera (or a friend with one). Unluck for me, it dismouted while using it (cheap loctite glue doesn't like the high vibrations and stress produced by the motor, yes a cheap motor), so i will try to remount it and take the shots.... takes time...

My attempt to build a fiber glass version of it brougth me to expending more than a hundred euros to realize brass shapes, without getting notthing from them, I hope at least I can get some plaster countershape from all that brass. Cause of this is my inexperience with working of composite materials, I'm going to fill this gap as soon as I find some money and time
