I just duplicated the horz stab from my lil Whiz plane using this method. Yes, it's thicker, but a heck of a lot stiffer. Had I been really thinking ahead, Io would have left the paper long on the front tabs to cover the seamline on the bottom. This requires a separate elevator but that's achievable in many simple ways. This is blue foamboard I got from the craft store, but I'm sure it will work on any kind.
