I can't say anything about how it runs because I haven't run mine yet. I will say I have only heard great things about it. I have a BME 115 in my QQ yak. I just weighed the whole setup ready to fly for a total weight of 24lbs. 12oz. This from an engine that is said to turn a 30x10 at 6200 on cans. I don't see how this engine could be over looked?
