1/4 scale is getting hard to find in A kit, I'm seeing mostly 60 size kits like the Tower Extra 300S at 64 inches or the Goldburg Extra 300L in 68 inches. I have built several of the CG kits and they would lend themselves well to A small gasser if you reinforce the area on the doubler just in front of the wing. Mine have been powered by OS and YS 1.20s and one with A YS 1.40. The first two didn't have the power for 3-D but I made the last one lighter and the 1.40 was getting with it!! More and more ARFs are taking the place of our kits.
