Posted by Best R/C on Jul 28, 2008
Designed expressly for F3C competition, the O.S. Engines 91HZ delivers the high-end power and hovering stability needed for executing competition-level heli maneuvers. For discriminating pilots looking for an edge!
- The piston and crankshaft are newly designed to further reduce vibration and improve torque stability over the entire rpm range.
- The rectangular heatsink has been designed to enable it to fit entirely inside the cooling shroud while maximizing the cooling effects and lowering operational temperatures.
- A thermo insulator on the carburetor blocks engine heat to ensure more stable fuel/air mix.
- Includes a needle valve control lever to allow for in-flight carb adjustments as needed for F3C competition.
