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.
