Very nice! I really enjoy a special engine with a story behind it. That HP is one rare engine for sure. One of my favorite engines is a YS 140 DZ that was given to me by a fellow RCU member. He had gotten it after a friend of his had the crank pin shear. It was in pretty bad shape but I sent it off to Richard Verano who pieced it back together for me. He used the crank from the 160 DZ because it has a heavier counter weight. This 140 resides in a 1988 Circus Hobbies Reed Falcon. An airplane I had wanted for almost 30 years before I managed to get my hands on one.
