Well I have finally seen this engine perform and man is it a ripper. Starting is a little bit harder then compared to my DA-50 but then again mine is a DA [>:]. The overall engine runs very smooth and has a lot of power at full throttle, a little more then my DA. The plane it was in is a Kangke Extra 330 with a 84" wingspan that died at a IMAC event the pilot (who is also a member at my field and has taught me pretty much all I know about doing aerobatics) was doing freestyle with it, the engine was still in good shape but I can't say the same for the airplane. But it will be going into a new Edge 540 soon and so I will try to get a Tach on it and really compare it to my DA-50 soon.
