Loft problem

I was trying to create a propeller blade surface using loft through foils. but I there are no “normal” lost option, only straight one, which made the loft result is not smooth at all, especially on the blade edges and the curve between the blade and the root. what should I do?b335.3dm (804.0 KB)

Hello - the file is in mm and the tolerance .01, but the curves are ~.05 mm. It looks like the thing really wants to be meters or? Scale it and things should act better.
