For the tanker lovers out there, PremairAircraft has released their freeware KC-135R for FS9/X.  A nice basic model that can be used for all sorts of things including online play and FS Recorder flights.  The boom is animated off a command that can be recorded with the Recorder module so it will play back correctly during subsequent flights.
They modeled reversers on the CFM-56 engines which the real life version does not use.  So just don't use them or edit them out of the cfg entry for maximum realism, or cheat and use them for ultra quick stops!
