Question about props

[Cadillac Performance Pts.]

Question about props guys. Why couldn't someone use a 4 blade and set the opposing blades (2) at one set up to pull hard down low and the other two and a pitch for more top end as long as it holds the engine for desired rpm> Like a dual plane intake with short runners and long runners. Just wondering and thanks.

more common with the warp drives, and there are pics around here somewhere.., i'll see if i can find the pic in member gallery....

ALRITE!!! I POSTED A REAL PIC, NOT JUST A LINK!!
this pic is of stacked warp drives, on 2 hubs, three blades each- but the blades are at different angles- not sure if this is what you meant, they do this with counter rotators as well, sometimes using different shaped blades as well as at diff. angles. maybe someone else could find those pics- i gotta go cook dinner for the (biggger) family !

I have ran a wide two blade and two narrow blades on a 4 blade hub! It had good and bad points!

Those turbo warp drives are pitched at 2 degrees different and where quiet
