My original question was for opinions on the 3w-106. I didnt mean to start a war. All of the mentioned 100cc class motors have their good and bad points. I was just wondering if the 106 was a good motor, thats all. By the way I love my DA-100 and my old 3w-100 (except when it flamed out in a low hover). I'll bet I would love a BME, ZDZ and a Kroma too, but my experiences are only with the 2 I own.
