The chord line is perpendicular to the shaft. Imagine a circle with the shaft as centerpoint.Perpendicular on the shaft means a circle around the shaft.In fact this is the relative air movement.If you don't get this approach,you won't understand what I'm talking about. If you make this circle intersect your blades close to the shaft you get a weird profile,also because of the 'muffle'(is this the right word?) of the pvc-pipe.
In my opinion the parts pointing forward near the center (on the broad side of the 'muffle')will be counterproductive.Cut them off. Only follow my advise if you understand what I mean and if you agree.
cheers, stonebrain
This is what -in my opinion!- have to be taken away to get rid as much as possible of the negative effect of the 'muffle'[ Parent ]
The blade looks a littel more like a conventional blade?
These are 4ft. I'm working on 5 and 8 ft versions. These 4ft are cut from 6" foam pipe.
My next hubs are made from Choice deck. Its that plastic wood stuff. It lasts forever and its not effected by watter.
