I always wondered if B units had some type of controls -- it didn't make sense that they always had to have an A unit attached in order to move. So by asking one question, I've learned two different things. That's why I love this place! <br /> <br />And that also means that I wasn't being very un-prototypical using a turntable to turn A and B units separately when they don't fit as a complete unit. Cool! <br /> <br />Thanks, Dave!
