Personally, I have found the R/CUniverse forum to be a place where a lot of very boring people like to get into little "Cock fights" over esoteric minutia!
Yumping Yimminy..... talk about being harsh! Chuckle... chuckle....
I've found it to be a place where a lot of very sharp people help a lot of other people. (And some of the posters try to throw in a little humor every once in awhile.) Guess one's perspective really matters.
But I've been doing this model flying stuff since hmmmm.... the '50s.... and the first square TEs I saw really were on models that had been built by guys who didn't know much about aero and had made a mistake. Really. Honest. And darned if it really didn't happen that the next guys to embrace the practice were the ones who only painted 2 coats of paint, didn't fuel proof the insides, didn't cut off bolts that stuck WAY out unnecessarily, wouldn't have ironed a wrinkled ARF if their life depended on it, etc. Honest. but whatever....
"but it's the truth, right?" It is.
