i just got a used Blast with an upgraded ESC (traxxas XL-1) and a bigger three blade prop. it is definetely fast but it overheats after only a couple of minutes. thankfully i was test running in a pool. it's done it with both a 6 and 7 cell. i was planning on gettin a water cooling kit for it anyway but i want to know if that will help and if anyone has any idea why its overheating like that. is it the prop? the ESC? i would appreciate any help.
