All the folks in China putting up ARFs are "professional builders that build for a fee" and usually for less than you can buy the parts. Give the builder a call and ask him for his thoughts.
If it's built the way you like with materials and components you're happy with - go for it. The only way to tell how a kit will fly is to fly it.
But it sure looks like a Great Planes ARF to me. Same wing access cut-outs and pattern in the internal frames. If so, it was built by someone in China.

Not that there is anything wrong with a GP ARF - Ihave an Ultimate 1.20 Bipeand a Giant Super Sportster that are both dandy.
