Well I see two problems with contacting GP about this. 1} I don't have enough of the plane to even prove I had one. 2} I cant prove that it wasn't an assembly error. I've owned a lot of GP products and this is the first I have ever had a problem with. I did like the plane and if it wasn't for the string of them falling out of the sky I would replace it. I figure I lost about a thousand dollars on this one, so from now on I'll stick to airframes that have proven track record.
