I have a blitz with a cc 4600kv. I run 7.4 lipo, and I keep melting spurs. I went through 5 this week. I've tried 88 and 82 tooth, I've also tried 14, 18, and 20 tooth pinions. I've also had the tech at the lhs look at all of them and even put some on himself. What is going on? Temps seem to be a little high when I run the 20tooth so I mainly run the 14 or 18. Any help would be great. Anyone else having this problem?
