Fiala VM 60 S1-4T with Starter

Exceptionally lightweight — approximately 2 lb lighter than comparable four-stroke engines in its class

High propeller efficiency — capable of turning large-diameter propellers efficiently within a practical RPM range

Distinctive four-stroke sound — large Honda valves and carefully engineered valve timing produce a deep, pleasing exhaust note

Excellent throttle response — immediate response with smooth, predictable transition throughout the mid-range

Compact frontal profile — valve train, carburetor, and exhaust components are positioned behind the cylinder to minimize frontal area

Nickel-silicon-plated cylinder surfaces for excellent wear resistance and durability

Fully enclosed valve train for improved protection and long-term reliability

Single-camshaft design for mechanical simplicity and reduced component count

Three-bearing crankshaft support for increased rigidity and durability

Microprocessor-controlled ignition with automatic ignition advance and retard

2S LiPo-compatible ignition system for convenient, lightweight power
