I'm finishing up the BUSA 1/6 N17 with fully flying rudder on pull pull. Not a big deal to build out.
It's an interesting point that modelers rarely talk about a "full-flying" rudder on the Nieuport or DrI or the Bristol 504...but of course it was. Full-flying just means the rudder wasn't attached to a vertical stabilizer fin. I suppose the reason the full-flying rudder on the EIII seems special is that the fuselage doesn't have a traditional vertical tail post so we can't just use ordinary hinges.
I read the bottom of the FF rudder is attached to the skid support. From the pic above I cannot tell if the pivot line is vertical or leaning forwward a bit. Either way it seems one would solder two small brass tubes vertically in two places. The skid touch point and the rear of fuse where it meets. Piano wire attached to rudder (L at top) slips in tubes with wheel collars..one below fuse (out of sight) and other top of skid, recessed effectively hidden.
The first photo shows the admittedly crude skid assemble on my EIII. What you can't see is that there's a sort of "loop" formed by the two skid legs and that a music wire passes through that. The music wire then passes through a tube built into the rudder. For the top pivot I used a carved down tail-wheel mounting bracket. The second photos shows another modeler's "cleaner" version.
