And since lower pitch props have been proven time and again to provide more thrust in static running, who would assume that they don't blow as much cooling air as a higher pitched prop? Someone who didn't understand all the important details?
And who had actually passed final say on how much cooling air is enough? Or even included it in the original myth?
Looks like it's been proven once again, that it's fairly easy to test whatever we want to find out and all we gotta do is test it.
But heck, this engine forum proves over and over again that it's lots more fun to contentiously argue and argue and argue.
What this thread needs now is for some fullscale pilots to start in with how it works in the real world and then get into a spitting match over who's right because they got the most hours.

Real modellers know that very little full-scale info is applicable to our R/C models. Which totally ticks off a full-scale pilot when they take up R/C and then discover that just about everything they thought they knew was wrong and now they are back to square one again.
Some of them really get ticked when they find out that now they are their own mechanic and they actually have to learn something about engines and airframes. I've seen droves of them quit the hobby over the years when they realized they couldn't call someone to maintain their models. <G>
Fortunately, even among full scale pilots, there are some very mechanically inclined folks that enjoy working on their models - just not enough of them.
Don't mind me. As an ex R/C flight instructor for nearly forty years, I've formed opinions about particular groups of folks seeking instruction. My best student pilots have been airline pilots. My least favorite students have been Army helicopter pilots and general aviation pilots. Not all of them were bad, mind you, but they are a more difficult group(s) to instruct than the general population. It is difficult to teach someone to fly when they are convinced that they know more than you, the instructor, and then won't keep their mouths shut long enough to absorb anything.
Sorry for going so far off topic. It's a two pill morning, if you know what I mean...
