Ok my setup is a IPC Pro Sport esc with a 15 turn motor. The esc seems to get too hot(uncomfortable to touch) after a couple of minutes of running. My gearing is fine and i've played with that already. It is quite hot out right now, so could that be the problem? I cant hold my finger on it for more than 3 seconds before it feels uncomfortable.

What kind of car is it in? Ambient temperature is definitely a part of it, but if you don't have it mounted where some air can flow over the heat sinks, that could be too.

That's odd, I run a 12 turn motor, in a T3, in Florida, during "winter" (ok, we don't have a winter, we have warm and hot, so what?!) and it didn't really get too warm. But outside temp. can definitely affect both motor/ESC temps. I run without heatsinks too...:D (ok, so I lost em.... :rolleyes: )

Farwar, it seems that you might need to install an electrolitic capacitor on your ESC (if you do not have one installed). That usually helps to bring the TEMP down on the newer PWM type ESC's. My recommendation is to use a 6800uf (microfard) 15V CAP. If you need a source contact me. I can get it for you and give you instructions on how to install it. Also, are you using a Schottky diode on your motor/ESC? That is a must (if your ESC does not have reverse only) That will help you get better battery time!
