I dont think running a 9.5t would have killed it that quick. Unless it was geared high and ran on 3s or some stressful running. I had the Reventon S. It wasnt the most powerful set up. I would beat if it blew right away you had a faulty ESC. I would return to SP for replacement. Even though Im about 100% sure your 9.5 didnt fry it, I wouldnt mention it when talking to SP
