RE: Spad XIII
I can remember back when I was doing serious static scale models and taking an Aurora Sopwith Tripe and converting it to a Pup and when I was done saying to myself that it would have been easier to scratch build it. I feel that applies even more to these animals because they just don't sit on a shelf collecting dust they have to fly! I'm working on my second BUSA kit a Fokker D7 and there's no way I would try to convert it to a serouse scale project. Its gets too complicated redoing someone else's engineering. My first scale attempt will be a scratch build.
On the subject of BUSA doing SPAD. YIKES How many days will it take to assemble it at the field. Four sets over interplane struts! If I were to do a SPAD I think I would consider a scale that I could transport without taking apart.
