I have two stock motors from Parallax, they are 7.2 volt and 310 rpm. My concern is that they are a little bit faster than I want them to be. I see that many people replace them, anyway. I'd prefer torque over speed, and I think a higher gear ratio will make it more stable. BTW, I'd like to thank Erco for finding the lower rpm replacement motors on Ebay. I guess I'll use the similar ones which are 70 rpms but 12 volt. I don't know yet if my 6 cells 7.2 volt NIMh battery pack would provide enough juice for them.
