As a builder and flyer of ridiculous sized airplanes, I see that it had plenty of power. After all, they are designed to fly on the wing, not the prop. For it's size, it was a very nice Zero....lots of sweat went in to that one. Hard to imagine if a total pre-flight had not been made. My corsair was ground tested for about an hour before its first flight. Altho ridiculous in size, it is in it's 4th year of flying, 50 flights, one gear up landing and no structural damage. HAve only broken 2 props. My point...unless you have flown an airplane of this magnitude, I don't think you should cast judgement on the scope of the project or the ability of the plane and pilot. Especially if you were not there. Danger is not directly correlated to the size of the model, as I often see and hear referred to. I've heard it a hundred times. All of these models are dangerous...even the .40 size. That's my opinion. For all we know, the radio went schitzo. I see the reversed aileron as it went in, but ?..... Suffice it to say, it was a nice model and too bad it was lost. Fortunately, only the airplane was hurt, and no individuals...the wallet, notwithstanding.
