Here is a video showcasing how this esc and motor combo causes my Maverick Quantum to "cog." The intended viewer for this video is the Amazon seller RC Mall. The RC car does not perform correctly when the motor and ESC is installed. When the car is accelerated, there is extreme hesitation from the motor, thus causing a grinding sound (also known as cogging). I believe that the ESC and motor are not correctly sending information to each other.
