The math for wing loading on page 18 is totally in error and it's not "PSI" as indicated but "PSF". The "reinforced" joints mentioned on page 19 were not added as a result of the "modifications" but, as I recall, were part of the original KR2 plans. Using the performance numbers directly from the Rand sales literature indicates to me that very little research was done to verify actual performance of the KR before they were used to make his assumptions or calculations. That's were I lost total faith in his conclusions. I'm even wondering about the qualifications of the three professors signing the cover page. But hey, that's just me. Your conclusions may vary. :-) Larry Flesner
