propnut1, I've read that the original engines were Italian and have since been taken over by the Chinese. Supposedly the carbs are better, I don't really know. But one known fix was an OS 70D carb. I just hate the idea of buying a $150 engine and then buying a $79 carb.Seems that for a few bucks more You can get a quality engine that You'd be proud to own... I am still doing some research, as I like the idea of a 38 oz 1.40 glow engine on a 10 plane.... yeeeehaaaa!!!!!! Best Regards, TJ
