Sorry to hear about your loss. I had the Sig cap and the extra and sold them both before I ever flew them. After hearing all the stories about the problem you had I didn't want to chance it. The guy I sold the cap to had bad flutter on the aielron and it went in. Sig has a serious problem with their 1/4 scale planes, not sure if it's quality control or what. I know alot of people havn't had any trouble with their wings but I'm going to stay away from them myself.

I would box that baby up and send it back to sig and see what they say, maybe they will at least send you a new kit.
