That is a good looking set of engines...I assume you are not running in Command??
Taking either motor out and you won't have a way to mount the truck to the frame. Getting rid of all the plastic gears is a good way to go. I use the metal post war set up. Are all programed the same number. If you want the rear engine facing the opposite way of the lead engine, you can get the rear going the way you want and lock it out with the program switch.
