With reference to my letter above I am serious about asking which way the water goes down the plughole!! Here at 43 degrees SOUTH latitude it goes down the plughole clockwise. To make sure I put a small piece of paper in the tub and watched it circle the plughole before disappearing. I have heard many times that the northern & southern hemispheres have different plughole rotation - is it true? Maybe someone can humour me and try it!
What`s this got to do with autogyros? Maybe not much! Cheers from the south Pacific.
