So, generally if the motor is getting too hot, try gearing up even though it sounds backwards. And if the ESC is cooking, try gearing down.
But.... this isn't always the case of course, and depends on the the entire setup... which esc, etc. An esc that can barely handle the setup might run hot no matter what... while a Monster Max might stay cool even when the gearing is too tall for the motor. So there are no hard and fast rules...
And some motors will run hot in a particular car no matter what the gearing. For example, a Feigao L can motor in a 1/8 buggy is going to run pretty hot even with a good gearing, while a Neu 1512 can be geared all over the place without cooking.
Hmm... trying to get my brain around this one. So if the motor gets hot, it is because it is spinning too fast hence the need to up the gearing? However, if you up the gearing, wouldn't it get hot because it might not be strong enough for the higher gearing?
My Neu's seem to run around 150+/- degrees on a track and typically less than 110 degrees on the street.
