Glad to hear it is working out for you Bill. I got another flight on mine with the OS .52, while much better, the engine ran consistant, I'm not getting the RPM out of it. OS says it should run about 12k and I'm about 1500 short of that.Maybe they are dreaming I don't know.

I might be looking for a YS to put in it and might go on. The plane is flying on the .52 but can only go about 50 feet at a 45 degree angle before dropping out. Maybe if I quit flying it on 15-25mph windy days I'll see a little more out of it.
