I've used, and still using, a 35A Hobbywing EZRun speed control in my one stadium truck. It came paired with a 4300kv F540 brushless motor. I was very sceptical of the combo lasting any great length of time. That was back in 2010. The motor has since past, but the ESC lives on. That little Hobbywing speed control started my love affair for the brand. Whenever I want a reliable ESC, that's where I look first. I believe some brands are more robust than others, but I go with general spec recommendations for ESCs and motors.
