This is the YS FZ115-S 4-Stroke Glow Airplane Engine. The FZ115-S is the most powerful 110 class four stroke engine available from YS. This engine delivers a variety of exclusive and proven features that have made YS a favorite among demanding enthusiasts. The supercharged system uses a simplified structure to keep weight to a minimum while still retaining maximum efficiency. The air chamber uses crankcase pressure coupled with a double throttle valve system that allows a bigger charge of fuel and air mixture to enter the intake valve for more power. Finally, the fuel injection system provides superior throttle response and is unaffected by tank position or by the attitude of the model.


  • Regulator designed for ease of operation
  • Proven Fuel injection system for superior throttle response
  • Ring sealed crankshaft to increase crankcase boost for more power
  • Same mounting pattern as YS110FZ-S
