Even with your ARF repairing experience I would advise a smaller more basic type kit for your first build. Maybe save that 20cc gas for your second or third build. A Sig 4 Star in the 120 size would allow you to use that 20cc gas and still be a doable first build. They are great flyers and can also be built as a clipped wing more aerobatic plane. What airplanes do you like??
I think you are on the right track. The 1/4 scale Cubs are probably a bit much, when learning how to build. The Sig 1/5, and the Great Planes Cub .60 should be doable. The problem would be that I doubt the 20cc will fit in either cowl.
The 4 Star 120 may be the ideal solution. It's a larger airframe, but it contains a simplified building technique. The 20cc should power it well.
