I bought a pinion form mike and it came in less than two days (being about 40 miles away doesn't hurt either). I ran it with the 13T still with the 9L and it definately ran cooler, still too hot to touch after about 4 seconds though and the runtime was aboout 9 minutes. The ESC was less than burning too. And the bettery temp was in check.

I assume the 9s will give faster speeds and longer runtimes. It's weird to think that it will. The 9L was just overall slow and innefficient.
