MAXIMUM MUSCLE - MINIMUM MESS!

The O.S. 110FS-a 4-Stroke Engine never compromises on performance, delivering 12.5% more power than the FS-91SII in the same space, but now it features a PD-08 fuel pump to deliver fuel consistently to the engine for better response and reliability. High performance doesn't mean high maintenance with this engine. Ideal for aerobatics and other situations that require high power, the 110FS-a also features the ingenious recirculation system that re-lubricates parts instead of venting the oil out into the cowl!

• Adjustable F-5040 muffler can be rotated 360° and moved in or out for a perfect fit. Rich, deep sound is an added benefit.
• Features the same mounting bolt pattern as the FS-91SII for easy replacement. Reversible carb and narrower camshaft housing simplify installation.
• Tighter tolerances and updated engineering reduce maintenance and ease set-up.
