super_micro, the Mini-X is more like a hopped-up Micro with the 6-cell. Not only is the Mini-X incredibly fast with the 6-cell, it is also amazingly easy to control even with all the extra power. I have a stable full of extremely high powered Mini-Zs, and while they are very fast, they require a great deal of skill in order not to roll, understeer, etc. The Mini-X is more point and shoot, the 4WD system makes it a dream to drive rather than a constant challenge. Not only will you outrun your friends' Zs in the straights (unless they are running a Mini-ZRacer.com motor
) but you will also be able to carry a lot more speed through the corners due to the X's wide stance and 4WD.
