Sorry to hear of the unscheduled landing!
I have had the 54" version with a Magnum .52 four stroke on it for about 2 years. The first flight on mine was like holding a wildcat by the tail! The problem was that the stated CG was way to far aft. After I added a few ounces of lead in the nose, it flew quite nicely. Helmut at Dymond has been very helpful to me each time I had any problems with his products. I would try dieseldan's suggestion and call once more to see if he would sell you a wing.
