An 18X10 isn't ''square''. You'll just have to believe in your own logic or try it for yourself. Try 9X10, 10X10, 11X11, 11X14(old stock) 16X16, I have.
Nuf said, I'm moving on.

Not square but not at right angles either. The prop pulls in airflow and the airflow prevents it from stalling. Even the 9-10 above isn't even close to stalling. Axial fans don't stall even with ductwork and with pitch angles much greater than a 9-10.
