From: £384.00

The first in a completely new series of four stroke engines. With its deliberately ‘retro’ styling reminiscent of the very first OS four strokes.

The original FS-120 had twin rocker covers and so do many full size engines in older aircraft. But ‘retro’ styling does not mean ‘retro’ technology! The FS-95V is a sophisticated engine, delivering strong power and torque and offers a cost effective alternative to the FSa-81.

The 60P carburettor is a twin needle design for great throttle response and 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 peace of mind responding just when you want it to. That is why so many discerning modellers choose OS time after time!

There are many models designed for .61 2-strokes / .91 4-strokes and 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 and variable length header pipe. Flexibility of silencer outlet position is well suited to scale installations and there are a variety of optional header pipes too, that will cater for just about every model.

The new ‘V’ series of OS four stroke engines is here and setting the industry standards yet again.

OS F Four Stroke Plug x2

This is without a doubt the 'de-facto' four stroke glow plug. Brilliant in all four stroke engines we have tried and definitely worth the extra ?. Also great in inverted Moki engines and other inverted 2 strokes - taking away some of the pain of starting and running and lower rpm.
