Poor construction maybe? My vxl ruster ran very hot with a 4000 3s lipo and stock gearing. I was not impressed with its performance at all. It seemed very power hungry, but not all that powerful. It heated up the battery way more than a comparable feigao/mm system did, both geared the same, in the same weight vehicle. Runtimes were also about half of the feigao/mm setup. I think that the esc is just ineffecient.
