I don't know about the 1/48 DH-2, but I have build the new Dr.! Sadly I don't have any pictures as it did not survive a house-move..
It is very fidly to build, but Eduard has made a very kit. There are resin formers to shape certain parts, mainly the leading edges of the wings. They work fantastic.
I made it some more difficult, I laced very thin white ez-wire through the wings as that is something you can clearly see in pictures of the wings without fabric. I don't know if it helped, but the wings were very firm.
This kit is very detailed, much more so then the old strip-down kits which I also build a life-time ago.
Not only the details on the photo-etch are much, much beter, the plastic and (resin) engine are much beter and even the instruction are much beter than teh old kits.
I made the old kits and sprayed them solid metal colours, they were fun to have in a display case, but the new kits is an amazing replica that can be made as a true skeleton aircraft.
I am temted to build an other some day if my eye sight holds up and maybe do a partly cover tith tissue paper or something like that.
Try them and you will not be dissapointed.
