O.S. ® 81FS-a Ringed 4-Stroke
The 81FS-a delivers more performance power for sport pilots and
more realistic fl ight for scale pilots — and for easy upgrades, features
the same mounting bolt pattern, distance between crankcase and
prop and throttle lever positions as the FS-70SII! A rubber O-ring
on the muffl er's multi-positional manifold helps prevent oil leakage,
while the specially designed lubrication system eliminates the need
for crankcase ventilation. Its 60RA carburetor is venturi-equipped,
reducing the chance of fuel leaks, while also creating more positive
air/fuel fl ow. OSMG0981
