RE: WW-1 combat?
Yeah, that's about the performance and size they were working with.
With luck one of those guys is still reading this forum and will chime in.
They actually had someone producing kits and selling them at a local hobby store. If I recall, you had to build one of those kits, though I could be wrong.
They were nice looking planes though. If I'd had more time I might have tried it.
