Actually the VXL-3S didn't overheat. It just stopped working after 3mins. I just noticed the data from my DPR-II-150 is a bit fuzzy. I will see if I can do something about that for the other controllers. After I test the MM, I will go ahead and try the MGM 16016-3S.
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.
Off the ground the VXL-3S works great, but as soon as it is on the ground it just fails in every aspect you look at it. It basically doesn't seem to switch the MOSFETs fast enough.
