well, just an update. I ran my hyper for another 2 minutes today! seems to run really good. LOTS of power with 2650kv/4s RC-M packs. so strong it deglued one of my tires. it was so cold outside that we had sweedish fish, and they froze, and when we picked it up they shattered, along with the zipties, etc... 11 degrees, windchill of 0. not the coldest its been, but not fun at all. at least i can say my MMM never needed to run the fan once!
also, i bet i'm the first to have a pic of the 2200 and the 2650 CC neus together!
