I do strictly 1/48 for about 99% of my WW1 models, I have been doing that scale since I started in the early 1990's building aurora kits that I was able to find at a local flea market. Then Eduard came out with their 1/48 scale kits and I have been at it ever since, buying up the Dragon, then Roden, then Special Hobby, as well as short run kits by Blue Max, Lone Star Models, Copper State, Jager, Omega, Karaya, and the latest from GasPatch. I have almost every type I would want to build in 1/48 (other than an AGO C.I or Caudron R.11). I find they are the right size for me, I can add interior detail and rig them well, and still fit them in my display cabinet. I have built 1 Nieuport 17 in 1/72 scale for an online challenge, although it was damaged when I brought it to the nationals so that ended my experiment with the small scale. I still have the old Revell 1/28 scale SPAD XIII, Fokker DR.1 and Fokker D.VII half built in boxes in the attic but will not have a spot to store them when or if I ever complete them, and cannot afford the new Wingnut Wings kits, nor would I have any room to display them.
