I searched the forums and couldn't find what I was looking for. Everytime I install a new prop, I have a problem holding the backplate still while I tighten the prop nut. I was wondering what ideas folks had come up with to get the prop set where you want it while still keeping the back plate in place. It seems that I can never get it *just right*. I either get the piston position a little off or the back plate not set to where the spinner fits right. I know this isn't really an issue with aluminum spinners, but I still have a couple planes that use the plastic ones with two screws. Any ideas?
