I have to date run this system for about 2 hours run time. Took out brushed system put this in, kept everything the same and hit the dirt....power compared to old system was enough to blow a tyre......it was great!(although some down time putting tyres back on) ESC is large and just fits into SC10 where the ESC goes, but I mounted mine on top of the battery tray with some zip ties to even weight out a little. ESC is easy to use even without programming card, but I will get one at some stage to fine tune. Seems to add some over steer to the truck so must be heavier then I am use to but that is easy solved. Extremely happy to date and a great price point on this system compared to comparable other manufactures system.
