[Spridgets] Diffs again, if I may

[derf]

The open diff will seek to turn the side with the least resistance.    If
one side is very easy to turn (broken axle) then it won't bother trying to
turn the other.  If you have a Phantom it will try to turn both, until the
force of the spring pack and plates against the planetary gears is
overcome.  I think you might be able to limp home with a Phantom, if you
accelerate very slowly.  I haven't used a Phantom so I'm not sure on this.
Good question for Phantom users and sellers.
