Hi,
In my early twenties, I buit a few planes but two that were easy to build and fly were the Goldberg Shoestring Stunter and the Sterling Ringmaster. Both have 42" wingspands and fly great with a Fox 35. Between the two, I prefer the Ringmaster but the Shoestring is very good also. By the way, I'm now 58 years old and I finally lost my Ringmaster after many, many crashes this last summer. Not bad for a plane over 35 years old. It was beyond rebuilding this time. Also I was using the same Fox 35 and still use that engine. My advice, a Ringmaster and Fox 35. Check out EBay, they have them there.
