Can 4S1P A123 power a Feigao 7XL

[hardmankam]

A little off topic:

If I were to place the motor to the front (opposite to the steering servo), that means I would have to raise the center diff 3-4mm from the chassis in order for the diff gear to clear the bottom, would this setup have any bad effects? or it is better to cut a diff gear slot on the bottom of the chassis?

Do I also have to raise the front and rear ends of the buggy as well to preserve the proper length/angle of the drivetrains?
