RE: 2 Stroke vs. 4 Stroke
Nope, didn't know that but my advanced flight instructor was one of the first guys in this country to get the YS for pattern flying. He was working at a big hobby shop at the time. He got me into the YS by allowing me to fly his CG Extra with the YS 1.20NC then my CG Extra with the OS 1.20, my plane was a bit lighter but it was apples and oranges. With the price jump by Saito and OS I can't understand anyone buying them when they can get a YS.
Does it sound like I'm sold on them?? Plus I can buy any and all parts for a YS without having to send them in for service. Another big plus.
