Smaller, quick turning ships turn far too quickly under FAOFF, so I pretty much never use it in a Vulture, Eagle, etc. Smaller medium ships (think the Asp) I use it in combat occasionally against those smaller, more agile ships. Larger medium ships (think Python) I use it all the time in combat to turn. Finally, the very large ships (Cutter, Anaconda) I use it even more in combat (it's off more than on). I also use FAOFF in them orientating the ships to line up with the mailslot or landing on a planet.
Hmm...I might take you up on the challenge, and do it in the Annie, even though that's probably cheating. I'll try another go with the Asp, and maybe even do one in the Vulture.
