when my new fliton arrives i will do the same thing double check the wings and more than likely ad extra glue. just to make sure. the plane is the cheep part the engine and electronics cost way more im sure you know since you use ys engines and i dont want to crash test them again. im not sure who you talked to and where but i talked to the US department and the person i talked to was more than helpfull. i have only been flying just a few years and only been flying arf's and believe me i have found a lot of manufactoring problems with other planes. one of which crashed. before the plane crashed i called the technical support and because i knew the plane was not right other than slow wide manuverse it would drop a wing and i had other 3d pilots fly the plane and they said it was not right. but anyway the tech support told me it was normal for a 3d plane to do that. well i lost a plane after just a month of having cus it dropped a wing and could not recover in time.
