I would like to know if anyone is actually using the recomended YS 120/140 in this plane and if so, how does it fly. I don't mean to shut anyone out, but I only want to hear from people with these or similar engines, not gassers or large Mokis. I have a 140 and am considering the plane. I just want to know if it will fly it properly.

I had a YS 140 in mine when it was new. The plane flew very well, no problems. On 30% fuel it had some vertical performance. If you just want a nice flier it will do fine.
