Keep the ideas coming!!!

Yeah a top plate would be way cool...

To lay the batts flat they would probably have to be locked in place by a top plate and that could make changing them harder.....If the chassis is designed to use the Mini-Z bodies only, then the width becomes wider and the batts could possibly be laid flat in holders. But then you need wider offset wheels.......might be able to hook up with Mini-Z to make the rims.............................................. ....


Rolling chassis, could be possible........
