They sell it separately for those who already own the "A" unit, so they're not wasting money re-purchasing it in the pack.
Oh, I hadn't thought of that. And they sell it for people who love B units and think they look awesome sitting at an engine terminal by themselves, like me.

I might attempt to learn how to model stuff, and try making a F7B unit. They had a 3 notch throttle, and a simple brake. You opened a porthole and stuck your head out of it to see where you were going.
