number of cells vs MM motor

Hello, i'am to build my electric Jato, and i don't know wich motor to put in.
I've a Mamba max speed control and i look for the MM 4600 motor.
Could i use 3 cells li-po with this motor and how this motor is compare to Feigao motor????

Plus, is the MM motor have the same mounting hole spacing than the Feigao XL motor, because my engine mount was made to accept my hold Feigao 8 XL in my electric LSP, and i want to modify this engine mount to put it in my Jato.

thank you:030:
