The highest achievement of O.S. Engines' manufacturing expertise. They're the spit and image of full-size light aircraft engines. Ringed piston construction gives them strength and durability.
Ball bearings minimize friction and wear.
Efficient carburetion boosts reliability and fuel economy. Low vibration levels protect your carefully assembled airframe. Four ball bearings and two needle bearings add smoothness. The design is naturally self-dampening, but seven ball bearings add extra glide. All include headers, glow plugs and mount.
