I squinted at the pictures in Datafile 59 (and 16) and am nearly convinced that the rudder-line is in front of the elevator on the Pfalz-E-type. Unfortunatelly, don't have any clear photos of the tail workings. I did notice how the rear-skid supports on the Fokker Eindecker are angled back - the Pfalz does not seem to do this. It looks to be the same as the MOrane Saulnier design. IMO, FOkker really simplified the geometry of his full-flying-tail monoplane by putting the rudder behind the elevator. On the Pfalz, there is a noticeable cutout in the rudder to allow clearance of the elevator behind the rudder line... but as I discovered building the model, it is a real task to get the shape just right to allow the rudder sufficient movement and to clear the elevator line. (and I certainly don't claim to have a perfect scale-implementation here!)
