Elvir - OK, now I understand. I'm not familiar with the Wesson engine, but that G20 gasser might be a good choice for you. As far as I'm concerned the Ucando is one of the best designs I've seen in the 20 years I've been flying. It is amazingly stable even at stall speeds, and so is very forgiving as you practice 3D stuff. Very light, very maneuverable. And it does amazingly well with a wide variety of engines. Personally, of the 24 planes I currently have flying, my 3 Ucandos (one in each size) are the ones that almost always go to the field. Really amazing planes.

Incidentally, my wife's grandparents came here from Croatia years ago, and my mother-in-law still speaks Croatian. I've heard it is beautiful - my wife would love to visit there some day. Happy flying!
