RE: oops, I suffered from over confidence.
I was lamost in the same boat this past weekend. As I was flying all alone at my home a few friends of mine, who don't fly and just like watching me fly, stopped in while I was still in the air. They also had another guy with them who has never seen rc planes flying before.
I was flying my 60 4* and was rather high trying to learn new tricks when one of the guys told me to bring it down closer so the new guy could see it better. Of course I did and I was just doing the kind of flying I am able to do and not worry so much about crashing. I flipped it inverted from about 15' off the ground and then when I went to flip it back upright I got the dumb thumbs and somehow saved it. I think my plane was cutting the grass just as I pulled it up.
I was able to cover my dump ***** attack up when they all started to say the "Holy s***" "That was cool" etc..... stuff. Since they do not fly and only watch they had no idea. However a few minutes latter they told me to do that again and I just said I was low on fuel and better bring it in.
