Outstanding performance at a price that offers outstanding value for money, this engine from SC will certainly astound.

Ballraced precision new improved Mkll series engines add up to more engine and more performance for your money. SC have chosen to feature precision ABC piston/liner assemblies in 99% of their 2-stroke engines (the new 180 2-stroke is ringed). SC 4 strokes are primarily ringed for the easier handling characteristics this gives 4-strokes. Additionally, every single engine is turned out with a twin ball bearing crankshaft so that each engine will continue to run smoothly throughout its life - the same as it did on day one.

L-OS30600£260.99
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.

SPECIFICATIONS
Displacement:10.11cc (0.617cu.in)
Power:1.1PS @ 10000rpm

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.

SPECIFICATIONS
Bore:29mm (1.142")

The FSa-56 is the first engine from the new 'Alpha' series of advanced four strokes. With increased levels of power and torque over its predecessor, the FS52 Surpass, the new FSa-56 has razor sharp throttle response, a new internal breather/oil recirculation system, and dramatic futuristic styling.

SPECIFICATIONS

The brilliant O.S. FSa-72 offers extremely compact external dimensions combined with excellent levels of power and torque. Like all the FSa series, the FSa-72 has internal crankcase oil re-circulation, a super-smooth carburettor with anti 'spit' inlet and an ultra-quiet silencer. If you have a flying field 'noise' problem, then this is the engine you need. The new 61N carburettor provides both linear and fuel efficient mixing to gain you reliability and precison control at all RPMs.

SPECIFICATIONS
Bore:27.0mm (1.063")
Displacement:0.72cu.in. (11.79cc)
Power Output:1.2PS @ 11,000rpm

The new FSa-81 is a direct replacement for the FS-70 Surpass II, offering greater power and throttle precision in a compact and lightweight design. The crankcase mounting dimensions allow the FSa-81 to slot into the same mount that an FS-70S II would for an instant power upgrade.

Like the FSa-56, the crankcase breather system has now been incorporated inside the engine to negate the need for an external vent and the excess oil that emanates from it. A propeller locknut assembly is of course standard.

The FSa-110-P is a great engine to increase power when you want to replace a .91 as it has the same mounting dimensions. Now you can enjoy the added benefit of a fuel pump with this new version of the 110FS-a. Plenty of torque to swing large props. Ideal for aerobatics and other situations that demand high power in all attitudes.
