Very well made and stays cool, I have two of them one in a Slash and one in a HPI touring car. Ok Slash first, it loves to be wide open on a lower punch control but change it to level 7 and hold on. Make sure to glue your tires very well or it will rip them off and I just use a Tacon 3930kv 2pole motor and a 3cell 60c battery, will try level 9 punch control with a 4pole motor next. As for the car I use a Traxxas Velineon motor. The punch control works very well on a track keeps you from spinning out. On the road I let it rip with a 3cell 40c battery and its everything you need and more, for 55 dollars you would think ok I'm getting what I paid for but you're not you're getting more for your money than high dollar brands.
