Nice job on the anti flip rollers. Me well I hadn't had that problem with my MS sport but I have a MB2.6 in mine. It runs like a bat out of hell and turns with out insedent even with the second cell on the back. Dop you used a open deck right? thats why unless you didn't put the cell in the cab of the body.<edit/ I chang my MS body to a Subaru WRX . My three cell had a biger problem tho. It wanted to pop a weele onto its back.
