adding weight for more traction?

[Exclusive RC]

The guys are all right... me personally, good tires metal wheels and DEF bbs in the tires and I will tell u why.... if u add weight anywhere else it will make the tires drop to the point of looking like they are flat... but with bbs in place it will keep that from happening... and also most importantly LOCK your diffs BOTH of them... contrary to popular belief.... in a toy having both diffs locked will NOT have any negative side effects...
