Myself , like Mark did not know Michael from Shinola... Thank you for your additions to that regard. I was simply making observations about obvious deficiencies, one of which you admit to having re-engineered on your own bird, with "vertical guides". I would double the area of that forward mounting point as well as add some means of lateral control to the rear of the unit. The design has obvious flaws, in my book, and I was merely pointing them out.
Stating something is well engineered because it has survived a crash is ridiculous. Remember how they used to build cars 60 years ago, you could drive them into a wall and not damage them, but they got shitty mileage and the occupants often suffered dreadfully in crash scenarios.
I have over forty years experience in this hobby as well as twenty plus years in full scale aviation. While I am not an engineer, "...in the true sense of the word...", I can spot possible problem areas pretty damn easily and accurately.
