O.S. FS-95V w/F-5050 Silencer L-OS30900 The first in a completely new series of four stroke engines aimed squarlely at the sport & scale modeller. Stying is deliberately retro & in keeping with the style of the very first OS four strokes. The original FS-120 had twin rocker covers & so do many full size engines in older aircraft. But retro stying does not mean retro technology! The FS-95V is a sophisticated piece of kit, delivering strong power & torque & offers a cost effective alternative to the FSa-81. The 60P carburettor is a twin needle design for great throttle response & reliable idling. There is nothing worse than having your engine cough at the wrong time when you really need a reliable response. The FS-95V will give you that pice of mind & respond just when you want it. That is why so many discerning modellers choose OS time after time! There are many models designed for. 61 2-strokes/.91 4-strokes & the FS-95V was created with that in mind. She will fit in anywhere that an FS-91S does, so model compatibility is not an issue. The added benefit, is far better silencing from the new F-5050, baffled, twin chamber silencer with an O-ring seal between the cast sections & variable length header pipe. Flexibility of silencer outlet position is well suited to scale installations & there are a variety of optional header pipes too, that will cater for just about every model.OS has always been at the forefront of safety, & continued use of a lock nut system for the propeller retention on the FS-95V is proof of this. The new V series of OS four stroke engines is here & setting the industry standards yet again. Specification Weight:592g (20.9oz)
