Need Some Input before i burn something up AGAIN !!!!

[TroubleMan]

Well Happy to report my truck is back together and i was happy to see they had the 54 spur and diff in stock i forgot the pinion so i ran the 16 and the truck was nice i only had a 4cell charged so i ran that and it seemed to want to top out or close to it. considering it's dark and i didn't drive the truck more than 150~175 feet away but i did drive at 80% was kinda rough on it and the fan never came on but at power up. i checked mid run to see if fan worked and it did but was not on. Motor was warmer than before but i geuss thats due to getting more rpm's nothing hot just warm. all in all i'd say she's fine now. Thanks Brian this truck means alot to me and it looks like i'll be bashin with my bud's in the am ! thanks again Nick !! P.S. i will be going to a 14 before i run 6s.
