Ed;

 I agree, Al.  

 

 I also made essential those points in my response the Rules of Thumb.

 

I’ll admit to not thoroughly reading all the posts lately.  Busy times.

 

Also remember that if your installation is not exactly like the one you may be borrowing ideas from,  then yours is a different installation and the variable values may not be the same, the interaction and/or cumulative effect may not be the same, and therefore your results may not be the same.

This is a key point.  Rules of thumb are just that; an approximation of the ballpark you should be in.  Every installation is different.  Best to do the analysis, and some testing (preferably before the first flight if you can).

 

BTW; ED – I admire the intelligence, thoroughness, and patience shown in your responses on this forum.  A service to all of us.  Look forward to meeting you when I get this bird flying.

 

Al
