I agree with the Bob that there have been no reports of failures (unlike the BOT ARF old by Tower Hobbies) prior to Jack's experience, but nevertheless still something that should be brought to his attention if one does occur. I have launched it pretty hard on occasion with no problem, although I tend to tap it up most of the time especially with a good head-wind. I love this model and prefer to fly it over my Escape. So far no structural problem is apparent. Just my $0.02.
