FL-70

It's a breakthrough in R/C engine technology: the performance of a 4-stroke, but with less maintenance. The FL-70 allows airplane modelers to enjoy higher torque, greater fuel economy and more realistic sound, in an engine that boasts a clean, efficient design. With the FL-70, there's no longer a need to fear 4-stroke sophistication — making it easy to step up to the benefits!

• All components at the rear of the engine are fixed, which reduces overall costs and maintenance.
• The newly designed 60W airbleed carburetor is easy to adjust.
• The front bearing is sealed to prevent oil leaks
• Also comes with a lightweight, compact F-4030 silencer and #F glow plug.

By utilizing pressure from the F-4030 silencer, the Aeropressure^TM system maintains more consistent fuel delivery regardless of your plane's attitude — which greatly improves performance during aerobatics.

Thanks to this newly designed cover plate, the FL-70 weighs approximately 20% less than the FS-70 Surpass II. It's made of a heat-resistant plastic that's nearly as durable as aluminum.

The FL-70 is the first engine from O.S. to incorporate a ringless piston/liner assembly, which reduces maintenance.
