OS MAX FS-64V including silencer

The FSV series represents a new generation of OS four-stroke engines with valve timing. Compared to the previous engines FS-Surpass and FS-? are characterized by higher performance while maintaining the same installation dimensions, which makes it possible to benefit without difficulty from the varied offer of kits and building plans of model airplanes constructed for OS engines in recent decades.

• The new lubrication system eliminates the need for crankcase ventilation, eliminating the overflow tube common to earlier generations of engines.
• The new Type 61T two-needle carburetor ensures stable and regular operation throughout the entire rev range and easy engine adjustment. The carburetor can be rotated 180° to direct the main needle to the other side of the engine.
• The new muffler with a larger volume and the ability to adjust the rear part with the exhaust port in the desired direction ensures effective damping and gives the engine a deep soft sound.

The FS 64V is a four-stroke engine with a valve train designed for model aircraft of all kinds, especially suitable for RC models. It is equipped with a two-needle type 61T carburetor. The basic set also includes an expansion muffler type F-4050. The orientation of the exhaust nozzle can be changed by rotating the rear part of the muffler by 360°, the orientation of the muffler body and the distance between the cylinder head and the muffler can be adjusted thanks to the threaded adapter.

• The crankshaft is threaded for a UNF 1/4-28 propeller nut, a set of OS lock nuts is supplied in the basic engine assembly for reliable propeller fastening.
• Recommended propeller dimensions: Sport and Acrobat: 12x7~8", 13x6" / Model: 13x7~8", 14x6"
• Recommended fuel tank: 220-300 ml; The 220 ml tank is enough for 13-14 minutes of flight, provided you don't fly at full throttle all the time.
• Recommended fuel: at least 18% castor or synthetic oil, 5-20% nitromethane.
• Recommended candle: OS MAX type F.
