Hello,
Ihave a losi slider that is stock. After about 6 or so laps it overhaets. Let it cool for a few minutes and it's fine until it heats up again. I tried replacing the motor and it didn't help.
Any advice would be helpful.

Trim the hood panel back where it slides underneath the helmet, and cut the visor out of the helmet, it re-directs some cooling air straight down onto the speed controller. Also check and make sure there is no binding in the drivetrain

I remember reading that it might have to be geared down one or two teeth on the pinion gear.
