    Cooling

    Looking for ideas on cooling the stock esc, I get about 15 minutes of bashing and the esc shuts down for a few minutes to cool. The motor doesn't feel hot but the esc cooks.

    Check to see if the ESC fan is working. What is your gearing? If the motor is cool and ESC is hot it means it's overgeared. Try dropping the gearing down.

    Truck is bone stock. The only thing was I bought 6000mah 50c packs that I run.

    Check the ESC fan is working and not broken.

    Not sure if your issue has been resolved, but if you are using a dust cover in high outside temps (85F or higher), then your ESC will not cool down despite the biggest and baddest fan out there.... you'll end up just blowing the hot air all over it and cook your ESC in a dust cover.

    If that is NOT the case, then you'll need to check airflow out of the X-maxx to ensure fresh air is able to circulate through the ESC.

    It also depends on where you are running.

    If you are in any kind of grass that dramatically increases rolling resistance and temps.

    Did you happen to install the smaller speed gear. That is meant for hard flat surfaces.

    You can use an extra fan if you want, I use it and works for me, very good temps.

    Always check for rolling resistance when you have a heating problem. Could have a bad bearing in the drive train.
