I needed a wing assembly for mine and I looked on the internet. Found what I needed but it's back-ordered. Apparently, broken wings are a pretty common problem for mine - The Flambeau Skyscraper. But they were able to send me a new stand in five days. Don't know if that is fast enough for you to have it before your next hunt, but you can find almost anything by just searching for the name of your deke and including 'warranty'.
By the way, MN is doing research on the effectiveness of these things. I had a hell of a hunt last week with mine. There were tons of ducks flying around and I got what I needed to decoy in. Then the battery died... Guess what - the ducks continued to fly but they didn't want anything to do with my spread. Flew right on by out of range.
