O.S. FL-70

£161.99

Recognising that four-stroke engines should be affordable to all modellers, the new FL-70 delivers strong performance at a budget price. That does not mean that quality has been sacrificed, that's not the OS way!!
The FL-70 has some simplified components like the carburettor and propeller driver, but in actual use you would never know. The FL-70 is the first OS four-stroke to feature an ABC piston/liner assembly and this imparts a unique sound to the engine when running.
Safety is still an important issue for OS and the FL-70 is still equipped with a double lock-nut system to retain the propeller.
Like its FS70 Surpass cousin there's still 1.1PS to play with so power is certainly not an issue.
