prevent pumped out fuel coming
into your eyes.

The FL-70 is an air-cooled, overhead-
valve four stroke engine for model aircraft
use. This engine is suitable for trainer,
sport and scale models.
This engine reduces maintenance by
incorporating the first O.S. ringless
piston/liner assembly. Also, a sealed front
bearing prevents oil leaks. The engine is
fitted with the new easy-to use O.S. 60W
airbleed carburetor. This engine is
designed so that more R/C pilots, from
hobby beginners to skilled Sunday fliers
may enjoy the performance advantages
of four stroke engines – greater fuel
economy, higher torque, lower noise and
realistic sound.
