Keep in mind it is a competition racing truck that is engineered to race on a 2s battery, around a 14t-16t pinion, for ten minutes max. races are usually 5-10 mins. Also it is VERY heavy for 2s. it is essentially a 1/8 buggy size and weight so it puts huge strain on electronics. put a 40mm fan on the motor, if that is what you're having temperature issues with. if it's the ESC, it should have a fan as well. if your esc has PWM, set it as low as possible. if the battery is getting hot, it isn't good enough quality (C-ratings lie bigtime, it is all marketing hype), or as mentioned if battery and/or motor is hot, make sure your drive train is spinning smoothly - if your bearings are gritty and/or gear mesh is too tight it'll cause huge strain on the motor to work too hard and your motor and battery will heat up big time.
