O.S. Engine 110FS-a 4-Stroke with Pump  [OSMG0991]

Fuel is delivered consistently to the engine at all times, regardless of the plane's attitude, for more reliable performance.
Ideal for aerobatics and other situations that demand high power
Includes an ingenious recirculation system that re-lubricates parts instead of venting the oil out into the cowl.
