These are my favorite three blades, but sadly Hobby-Lobby has stopped handling many of the high quality products and is pushing electric junk. These Graupners have wider blades and a little more weight for a glass smooth idle. I am not an APC fan in any way shape or form.
Graupner props are great props & yes they do make an excellent flywheel for lower reliable idle RPM.
