Prop Nut: Is there such thing as TOO tight?
I have a Dubro aluminum spinner prop nut on an O.S. FS40. Yesterday was the first time running the engine and I threw the propeven after I THOUGHT the damn thing was tight. I haven't run the engine again but I've tightened the spinner down to the point where outer ring of the spinner is bitting into the prop. I actually think I can get it even tighter, but I'm not sure how tight is too tight. First time using this type of spinner nut, so I'm just curios. Thanks!!
