Yes it was wired straight to the pcb and it had no problems. But what I have recently done was take that pcb and inplant it into a zipzap since it had more space for batteries. I have since been purchased four 1/4AAA batteries and have them installed under the pt crusier body. I am actually looking into getting a mod
that sessiz10 posted it involves

using smaller batteries that have a 40mah. It will be less run time than the stock batteries but the batteries I currently have in there are 50mah. I runs for between 3 and 5 minutes. Another thing about this mod is that I believe that car wont flip over as much as with the larger batteries installed.
I almost forgot that the pcb I am using is a clone one. Its called a fit racer and cost 10 bucks. I one main difference I noticed in the pcb from the zipzap one is that the chip is covered with a black blob and the fitracer has the chip exposed and is much larger. I will post a pic of it.
