O.S. 160FX Ringed w/ Muffler
X-tra performance power for sport and competition!
O.S. FX Series Engines feature dual bearings for durability and smooth operation, plus a low crankcase profile that allows for a proportionately taller, semi-squared head — a refinement that increases cooling fin area and improves heat dispersion. Plus, you'll never worry about losing a prop during flight — the threaded portion of FX crankshafts is extra-long to promote better engagement of the prop, nut and spinner and greater flight safety.The high-speed needle valve on every FX engine is mounted remotely for added protection. An O-ring and ratchet spring minimize "creep" due to air leaks and vibration.
