I get a charge out of those folks that decry the data given in engineering textbooks.
Where does that data come from? Its nothing more than the results of findings of thousands of individuals, both engineers and non engineers.
So you are going to ignore all of those individuals and say you know better. Thats pretty egotistical don't you think?
Perhaps I agree with the engineering textbooks but don't always agree with how some engineers interpret them.
Likewise, over the years I have certainly witnessed plenty of engineering practice and theory applied incorrectly.
+1 Personally I'm not a guy that wants to hear what something can't do, tell me what it CAN do LOL.
Dirtybird, do you know what the operating temp of your little chinese engine is?
No I do not know what the temperature of the engine is. I have been running it on a test bench with a smaller size prop and it seems to be breaking in nicely. Its hot. Its just that I cannot keep the muffler on. I have longer bolts and am going to wire them.
On the subject of engineering. Anytime anyone, including engineers, make an extrapolation of observed data, its questionable.
One of the worst extrapolations you constantly hear is,"I have been doing this for years and I have had no trouble". The basic problem is the environment you are in will probably not apply in all cases. It will have more credence if the statement is "the data collected by all people in this country finds this true". But then you are getting close to what is in the engineering handbook
