Looks like it worked ok.  Pic size ok, loaded fast etc.  Any particular reason for the camo colored blades?

   Looks like your blades have twist, good. Please tell us about the construction. Looks like they may be glass skinned with a wire trailing edge.

Looks to be a nice profile, I just hope aluminium holds together.

i dou"t if those metal rods will hold up--your blades will end up bending back and hitting the pole--or worse..thats a lot of blade just for on rod to hold ridged..

you could bury those blades in wood , like my angled wooden hub..
