I’ve seen a few of these before and always wondered how they were able to get away with this? It’s clearly where they got the shape. Only difference I can see is that they are flipped over.

The way they got away with it is the blades are not using the patented Vortalex trailing tip which makes it quiet. Mimar blades are far from quiet as unlike the Vortalex, the extended tip is the leading edge.

Ah, I see.

So basically, these are what a backwards Vortalex would sound like? :D

That's interesting.  Ironically the Ilg "Q" blade has a very exaggerated "leading" tip and very wide, curved trailing edge. Sort of opposite the Vortalex.



Having a 16" Vortalex and working on an Ilg 163; I can say with certainly the 163 is a whole lot quieter and seems to move a lot more air.
