I would suggest a short can motor for the sc10 4x4 becuase of it's limited space. The castle 3800kv 4 pole would be a good choice. If you want sensored you could try the tekin pro-4 motors or the Team Epic Revtech 4XS motors. For a esc i would suggest either the Mamba Max Pro, Tekin RX8, Or the Hobbywing Xerun 80amp or 150 amp esc. The hobbywing 120amp may work but i've never tried it.
