Hey Bill Thanks for the tips, Yeah I think I'm gonna get a few of these prototype boards and solder male pins in them. That would save some space. That chassis is using simple dc motors so I use the sn754410 driver as you can see on the prototype pic I've attached. I think this is as fast as it can move with duty cicle sets to 1.0 cause the weels are big and heavy
