This is the YS 70FZ-S 4-Stroke Glow Engine. Developed for demanding sport and aerobatic flight, the YS 70FZ-S is a drop in replacement for the previous YS-63 with the same noteworthy features as the 63 but with increased power delivery and a variety of improvements that will increase power and reliability! One of the most notable changes, is re-designed regulator placement allowing the 70FZ-S to run cooler in harsh environments. The lower crankcase has been strengthened to help prevent distortion during operation, while the cylinder is now "liner-less" for better heat transfer, which will aid performance in high heat conditions.
