I mean exactly that, plans; no matter if the come in dxf, dwg, sldprt, dat format, as long as you can build a plane with the info it contains. I'm thinking of just getting a 3 view of a WWII warbird, increase a 10% the wingspan and cut it in foam with a wingspan of about 1m, I've been searching the internet all day and I only found two designs of combat planes, but they were powered models.[]
