Hey Harvey, I ran your numbers on my thrust calculator and your YS110 would have to turn 15,200 rpm's with a 12 x 10 prop to run 144 mph. I have a YS110 and it will not turn 15,000 rpm's with ANY prop. That motor is only good for 12,000 max... I agree the OS120 is heavy. Probably 4-5 ounces heavier than the YS110. But I am not trying to turn high rpm's just need the torque to turn the higher pitch props. My bud has a pitch meter and we are going to re-pitch a 13 inch prop to a 13 x 16 to try it. This setup just needs a lot of brute strength to hit 10,000 rpm's... Just a different approach to speed than the high rpm 2-strokes... We'll see how it goes... I am using my YS110 in a Funtana 90 right now. Ray
