Hey All, just got the ET, super excited, planning to build this week. Small question, planning to buy Hobbywing SCT combo....I don't know the difference between 3660 and 3652 motor, believe it's size, right? One guy recommended 3652 motor because it's a tad smaller, but another guy recommended 3660 because it has more torque. Planning to run this indoor clay track, OCRC. For ESC, planning to get Hobbywing XR8 SCT Pro. Any advice on which motor to choose.
