A BME, or any other large gasser, is not a "plug and play" engine, the owner should have at least a basic knowledge of gas engines...There are too many "newbies" who think all you need is a big engine and a plane, put it together and fly....People like that get a big gasser and have problems, then blame the manufacturer for their lack of knowledge...There are over 100 BME 115s out there already, hardly a brand new engine...It's based on the knowlege gained from the earlier BME engines....
