About a month ago when I took my Xtra Eazy 2 trainer to the field for the first time I had like 3-4 guys run over to it as soon as they noticed it. They all looked at the engine and then said: "Good, it's got the Evolution!" Mine runs great! I don't know what used to be in Xtra Eazy planes, but it scared people. The guys at the field love my EVO .46 I'm too new to advise anyone about engines. Mine starts, never dies. The "real pilots" at my club don't mind helping me with my plane cuz 2 flicks and the engine will haul butt till the tank is empty. And it was never "broken in" as per the manual.
