I ran my v3 for the first time this weekend. Took it to the track and ran the snot out of it. Ran five full packs straight through (20+ minutes each run) and not a single issue. The fan still works. Cogging was practically non-existant. I noticed that it is smoother when I spin out and the car rolls backwards - It didn't cog at all.

Did I mention the fan still works!!! First one that has survived more than 2 minutes with me. Temps never got about 90 on the speed control after a run (It was only about 45-50 degrees indoors, but still phenomenal).
