What keeps a clockwise rotating left hand threaded 4mm prop on the shaft? Are the threads reversed and if so where do you get that type of shaft. If that is not the case then what prevents the prop from spinning off the shaft?

yes they are!
look at Graupner shaft (yeah I'm in France! so almost only use Graupner) they only sell complete assy. shaft and tube with right thread and left thread shaft are available in 310mm long (not sure may be 320) for replacement of the original when using a left prop.
