Hi, both the motor and esc were just pulled from a brand new Team Associated Rival MT8. The only thing I did was solder a better connector on the ESC. The XT90 is much better than a Deans for connectivity. For reference the motor size is 40(Día) X 68(L)mm and the esc is roughly. 60(L)x48(W)x40.5(H)mm.
