It is not the truck. It will be the motor. I burnt mine up trying this. I had heat sink on it to. Fried the windings in side. If you want that fast try a 7 xl or 8 xl on 20 cells. I had a 7 xl and it would run with traffic on 55mph highway. I crashed that in the 50s and it tore the motor apart. The 7 xl may be a better choice for what you trying. jMO
