RE: 1/2 A Warthog Flies!!!! YeHaaaaa!
I have plans for a twin 1/2A wart hog (for TD .049) from Joe Demarco prints. PM me if anybody wants a copy and I'll see if I can arange to have the plans duplicated and sent out. They are printed front/back and in two colors, so I don't reccomend this as a beginner scratchbuild, but anybody could build it with no problems if you've done one before.
I believe they came as a centerfold in MAN back in the mid 80's or something, I've been meaning to build the thing for ages now. Perhaps when I get home I'll get to cutting up some balsa.
