i had a similar problem the right wing from what i can tell separated from the airplane in midair just leaving the wing truss with rubberband holding it in place.[i think that's what it's called] but anyways i called fliton and they had me send photos and a week later i talked to them and they cut me a good deal with a new plane. they did tell me that it was hard to say what was at fault and that is true but its nice to know that they do stand behind there product and i found the customer service to be nothing less than great. i found that it's usually easier to get good help by calling that just by sending an email.
