Designed as a replacement for the long established Max 61FX, the new Max 65AX has all the features of the new AX series, such the same mounting bolt pattern and silencer bolt dimensions, making a direct replacement for most 61 class engines. The real bonus is more power and torque for the same basic external dimensions.

Like all the AX series, cooling has been improved by the use of deep finning on the crankcase and cylinder head combined with the new fin pack shape.

The silencer is effective and a great benefit to flying fields with sensitive noise iossues.

The second engine in the new 'V' series of O.S. four strokes is targeted at both sports and scale modellers alike.

Like the FS-95V, the FS-62V has the same 'classic' overall design that appeals to scale modellers that like their engines to remain in character with the model. The performance, on the other hand, is very much 21st Century and builds on the O.S. tradition of constant technological advancement with each new range. In the case of the 'V' series, there is also a strong emphasis on value for money.

The carburettor remains as the twin-needle type for both power and throttle response and the 'Jet Stream' generation silencer allows both flexibility of orientation as well as effective sound reduction.

By sharing the same mounting bolt pattern as the FS-52 Surpass and FSa-56, mounting the FS-62V as a direct replacement is easy and convenient.

The angled pushrod and valve layout allows a better shape of combustion chamber, providing better power and efficiency.

Brand: OS

The first in a completely new series of four stroke engines aimed squarlely at the sport and scale modeller.

Stying is deliberately 'retro' and in keeping with the style 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' stying does not mean 'retro' technology! The FS-95V is a sophisticated piece of kit, 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.
