Strad,
I know it's too late to do anything different, but did you contact Horizon Hobby?
You pay more for their products for a reason -- their support is *nothing* like HK's. While they won't replace every burnt-out-crashed part (after all, you broke it), they tend to err on the side of the customer if it even hints to a defect.
HK and the like has us so trained for the "they have my money, they'll never help again", it's easy to forget there are some companies that still stand behind their products.
