The OS Engine OS FS-64V 4-stroke engine sets a new standard for basic 4-cycle engines. It is designed for sport or scale models and comes with an F-4051 exhaust and an F-type spark plug.

Features

  • Newly designed cylinder head is adopted along with the increased displacement
  • Internal capacity of the combustion chamber has been expanded to achieve a more 4-stroke exhaust sound and power feel
  • Comes with an F-4051 silencer
  • Drive washer has been changed to a machined aluminium keyway type
  • Additional standard equipment is a set of lock nuts that prevent the propeller from coming off

Product Information

By increasing the stroke, not only propellers of 12x7-8 and 13x6 sizes, but also propellers with large loads (13x7-8, 14x6) can fly lightly without losing power.

A newly designed cylinder head was adopted along with the increased displacement. The internal capacity of the combustion chamber has been expanded to achieve a more 4-stroke exhaust sound and power feel. 

The F-4051 silencer, which is a unique design of the V series, has revised the internal dimensions and improved the exhaust efficiency while maintaining the comfortable 4-cycle sound. 

The drive washer has been changed to a machined aluminium keyway type. A lock nut that prevents the propeller from popping out, which has a proven track record as a safety measure, is standard equipment.
