Flyboy Dave,

Apparenty I was unclear on the concept of a "moderator."

The thread starts out with talk about breaking in engines at "extreme" rpm, with statements like "let it scream" and references to running BIG engines on "toothpick" props (I'll bet that's not in the manual) while guys' buddies holler at them to "shut it down, it's gonna blow" and they grin about it ... you encourage them by saying things like "You're a man after my own heart" and personally admitting to exceeding the manufacturer's own stated rpm limits -- not just once but habitually, and with pride. Then I show up and say watch it, that's dangerous, these things can let go suddenly, it happened to me -- and you call me an idiot with a "load of crap."

Who was it that was going to run a GMS .47 on an 8 x 6 propeller? Was it you, or one of the contributors? -- I guess it doesn't really matter. If you want "extreme" rpm with a prop in that size range, your choices are to (a) use a larger prop with a beefier hub and cut it down so it will spin, or to (b) just grab some tiny nylon thing off the shelf, with an even SMALLER hub, and trust it with your life. How am I stupid because I chose (a) ... and why am I a jerk to say that at least one, maybe all, synthetic props have a limit, and YOU HAVE NO IDEA HOW CLOSE YOU ARE TO IT?

Instead of passing along this friendly (although anxious) warning to your readers, or maybe asking for a few more specifics, instead you pound your chest and proclaim that you're going to "hammer down" the messenger who brings anything but sunny news.

Well, obviously, nothing will penetrate your thick skull except maybe a chunk of glass-filled nylon. Have fun, I'll watch for you on the local news!

Just Some Jerk
