I had a similar problem yesterday. The wings did not sit flush with both sides of fuse, was like the wing tube was too long, then of course the wings were stuck on! Well after 35 minutes of "gently" twisting and pulling the wings finally came off. A closer inspection revealed that the sheeting was cracked a both wing tips, not to mention the dings and bruises encountered during the 35 minute extraction process. If this keeps happening there will be no wings!
