Sorry Darock, I find that I don't pay attention to smileys, I feel they clutter-up the dialog! Also, I find it a hassle to go to the smiley box an determine a definition for the one posted; so, I've gotten to the point where I don't even see them.

If we correct my mistake here, I am still going to go with my statement "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"! However, in this statement, maybe it would be more correct to change "a lot" to "some".

Getting back to squared corners: In my example (The Hanger 9 FuntanaS .40 3D) this airplane was designed, I believe by Mike McConville in co-operation with Sebastiano Silvresti. These two folks know so very much more then I do about R/C planes, I had no doubt that the reason for the squared T.E.s was sound. I only wanted to know what the reason was. I took a stab at it being to reduce flutter. Dr1 and Ed Moorman confirmed my suspicions.
