E-mail Henry or Jeffrey at Hobbyfan, I'm sure they'll be happy to send you a replacement. I would advise against making up a story to get a free part though, they may ask for pictures of the "defective part", they did when I had a bad VF-4 canopy they replaced, free, because of a defect they overlooked. So be honest, they may charge you a small fee cause it wasn't their fault, or they may just be cool with you and send it free anyways because you were honest about it.
