Not being rude, when was the last time you tried to evaluate the glue joints in the tail of the plane? This is almost impossible. The appearance of the plane looked super. Hot glue joints don't survive the knock of a 100cc engine. This I believe what happened to this plane. I have several ARFs but nothing this big. The pilot did not induce this failure. Tthe manufacture did this. Many posters have brought this to light and I still hold the manufactire responsible for this tragedy.
