I have seen the Moki's starting to show up at the flying more and more each month and I have not heard one bad thing about them. I think it is a good alternative over the OS 1.60 and the BGX but the oS BGX is still a damn good motor putting out a lot of power but it along with all OS engines it is just priced to high when compared to Moki. I am just glad we now have more to choose from.
My flying buddy has a Moki 1.35 in a Carl Goldberg Jungmann and it is pure pleasure to fly and the power is outstanding. I also like the 0% fuel it needs which sure cuts down on the dollars per flight as compared to my Saito 180.
