i tried the same thing when i did my first swap, i desoldered the crystal and put it into the zip controller, didnt work, there more to it than that. so i dont have any of my cars that actually use zip controllers, which is ok because they suck, unless you have little fingers that can actually control it. i much prefer the knockoff controller or a bit controller with the big square buttons, mush easier!! oh yeah, another tip on the pcb swap is to write down where all the wires go for each pcb and what color goes where, they are almost always different colors. also on the steering wires pay very close attention to stripes on the wires and where they attach at the pcb, if not you will be confused as to why it doesnt steer right and you'll be doing it all over again
