Just pick your size. The plans from Cleveland are normally quite detailed, however, they were originally designed for rubber power, so some beefing up in the nose section and possibly the main spars will be needed.
I did the Bellanca Airbus from them. I added some 1/8" lite ply into the fuselage in the nose and used spruce for the main spars. Plane flies very nicely.
