CD:

Have had a little Tony. They are decent flying sport airframes, you will enjoy it. It is quick enough, but not what I would call fast even with a Jett engine in it. Do not expect to be outrunning everyone except other sport airframes. I have destroyed several tanks with the the ys pressure, they were junk tank that came with the plane. Those hve inproved but not on par with the say Sullivan or DuBro tanks. If you use the stock tank, buy a small Dubro or sullivan tank and use the end stopper and fuel lines from that, The stoppers are the primary problems with the Chinese tanks. I have YS 63, 110, and 120, love them all. Stay with OS F plugs. Have always used Power Master 15% in all my stuff with no problems so I can have one standard fuel. Principally fly 3D with the YS engines. Am seeing more and more 4 strokes in speed applications with success. I don't have the heart to wind these little guys up that hard and expect them to be reliable long term, but thats just me. Keep them smokeing and valves adjusted correctly, and you should not have problems. ENJOY
