YS 140 Sport
The YS 140 Sport
fits the same mounting pattern as the YS 120's and 140's
This engine is very easy to operate with smooth running
characteristics and the ability to run well on fuel in a
variety of nitro percentages. But we still
recommend YS
20/20 fuel for best results. Fits the same area as the 1.20.
