OK. I'm pretty sure that a tail will alway have an
influence in flight, though. It's effect will not be
neutral. Maybe I misunderstand you.

I should be more specific. Placing a short broad tail
close to the body, rather than extended on a long tail
will allow you to move up or down faster. It takes
more time for the long tail to move in a distal arch,
right? Rolling is another matter entirely.
