i've had requests for a pic of my electronics layout. so here it is. esc in the rear, receiver as far forward as possible just mm behind the steering belcranks to make it easier to access the center diff (see build tip #7). the receiver is absent at the moment because my D812 is borrowing it but you can see where the receiver tray is located. battery location is full forward. the main reason i chose this arrangement as opposed to the esc forward is so that i can use a short sensor wire.
