yes they did. i called them and told them about the issue and he told me that the plane does that so i continued to fly it until it demolition. i bought a fliton edge just to see if any similarities and this plane flew awsome this plane will wall like it hits a wall unlike the funtana which would just flop over. i sent them an email about it to customer service and they said to send it in so i did. they said they would replace it no charge. since it was on back order the let me switch to the showtime 50. there customer service is great wont hesitate to by a hanger 9 plane again.
