I'm building the p-40 also and planned on making a balsa insert out of scrap that will fit inside the spinner. I'll have to put the shaft thru the thrust bearing and anchor it in the balsa insert first,glue it inside the spinner,then attach the blades to the spinner. You can make a small washer out of plastic and super-glue it to the shaft behind the thrust bearing to get your spacing.Hope this helps. I have the laser cut kit and it sure is going together nice.
