30" (760mm) Mini Cat Hot Fast RC Sport Flier
This forum has a few that like a hot yet small sport ship. This plan from 1993 Radio Modeller was just posted on Outerzone. Looks like it would be good for anything from a .020 Tee Dee on up to a .10, not for the faint of heart.

Just sharing the wealth.

I think it would be just a tad much for an .020, but with a sturdy .049, it should fly well enough.
Being a lazy builder, I never cared much for the one piece sheet spars. My inclination would be to use 3/16" sq. spars, upper and lower at the maximum airfoil thickness and add spar webs 2/3 of the way out the wing. Since the wing has partial sheeting on the top and bottom, the webs could probably be left out completely and have no loss of strength. Another option would be to keep the webbing full length, add false ribs in mid-bay and drop the LE sheeting entirely, except in the center section.
All in all, the Mini Cat has nice aesthetics.
