Are any of these free plans?

I'm trying to find a decent set of plans to make a homebuilt foamy from.
Whatever the plan size, I will be scaling up to get around 1500 in/sq to go with the 26cc ryobi 4 stroke weed wacker conversion I'm doing. Its supposed to turn a 18x12 at around 5500 rpm giving about 10 lbs thrust with a 60 mph pitch speed and should weigh about 4lbs after conversion. Any plane that would fly well with a g-23 should do well with my ryobi.
I belive I should'nt have too much trouble staying under 12lbs RTF.

Any help in finding free plans would be appreciated.

Thanks you,
