I have been running this engine for months now. This new generation long stroke provides superior power when using the Hatori SB-19 over the older generation YS 91.
I just wanted to let you know how much I enjoyed your school. It has helped me to get to the next level in my flying abilities. The help on setup and flying is priceless! I would recommend it to anybody that wants a boost in confidence or take that next step to improve flying skills.
