SIG L T 40 kadet wing breaks apart in mid flight crash rc airplane

the nylon wing screw ( the head was broke off) in the crash damage so we think that it broke then the wing got lose and broke in half crazy stuff ... thats why I try to film everything....I have started a rc forum for rc pilots to go talk and learn from each other please join me on face book I am trying to bring as many pilots and newcomers to this hobby as I can and with the volume of people on facebook we can really make a community of pilots to gain knowage from. for example if someone asks me a question I cant solve . I will post it for all the fans to. see in your news feed. then everyone can help. So the more pilots the better
