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 took the Freestyle 3D school and was blown away by their personal attention to me and my flying. Todd and Matt taught me the skills to be a better-quality pilot. Their knowledge of model helicopter setups greatly improved my proficiency. Their gift for teaching is amazing, and it will propel you to the next level. Not only do they do an excellent job while you are in the class, but they also provide you with the skills to continue to teach yourself. Thank you Todd and Matt for making me a better pilot while giving me the skills to learn new maneuvers.
