Arlington is home to a FW149 piston engined trainer.  I have seen a few over the years but they aren’t too common.  This one is painted up in German colors too.  I have only seen it flying from a distance but it has taxied close to me a couple of times while up there.  Theses are the shots I have got of it so far.  At some point I will get to see it flying in decent conditions.  The original design is actually by Piaggio but it was license produced in Germany.
