I was off today so got a bit more done. I made a nose cone, radiators, piping, sliding door on the top of the engineer's area behind the engine, new turtle deck and bottom wing attachment points. I also needed to lengthen my cabane struts as I forgot that the Staaken kit has these attaching on top of a rather modern shoe-box-like enclosed cockpit but my bashed R.IV lacks this so they were a a couple scale feet too short. A bit of brass wire and plastic did the trick.
This is coming along well. Tomorrow I'll fill seams, work on the dorsal gunner's stations, make a floor gunner area and maybe work on how the tails will at least fit.
Oh, yeah...must start vacuforming the new nacelles too. Wish me luck.
Cheers and thanks for looking.
