New Brushless With Some Issues

[brijar]

Sorry, I had typed that post before and had said that I was running a 9L/9920 and 13 GP3300's, but it logged me out as I went to post it, so I had to type it again and just forgot or was too lazy to type all of it. Oh ya, it is about 30 - 35 degrees out here when I was running, so the motor coulda been a lot hotter.
I just got back from my second run (actually third because I ran my cheapo 7-cells, but they were so weak and short, it doesn't count:025:), which is always about 1/4 as long as the first due to something stupid about my batteries. I had switched to a 14 tooth pinion and the motor wasn't very hot, but still warm. It didn't go as fast as the 16t did (duh!), so I don't know what to do. I didn't check the heat of the motor on my first run untill I was taking it in after the high speed runs in second gear and my hand was awfully warm due to the heat rising off the motor while carrying it. I may try to lighten it by removing the rollcage, but right now, it makes good insurance so I don't hurt my motor or esc in a crash. I do have a spare heat sink lying around, so I'll throw it on there and see if things improve. I didn't put it on there in the first place because I liked the shiny finish of the 9L and I didn't want to put any scratches on it because the heat sink is not very forgiving. I have one steel idler as you guys were out of stock of the pair and I have it in first gear right now.
I would like to gear for speed in second gear. I will probably do most of my running in second. I think I will switch back to the 16t pinion and stick on my heat sink. Thanks for your replies so far!

Happy Maxxin',
