O. S. ENGINES® 91HZ-PS 3D RINGED HELI ENGINE

 

 

Taking 3D performance to another level!

 

The O.S. 91HZ-PS 3D Ringed Heli engine features a redesigned integral regulator that is positioned horizontally and is machined for higher quality and more durability.  The regulator works with a fuel pump that delivers a steady supply of fuel at any attitude – even during extreme 3D maneuvers.  The piston and crankshaft are designed to reduce vibration and improve torque stability over the entire rpm range.  The heatsink is entirely enclosed to lower operating temperatures and a thermo insulator on the 61B-PII carb blocks engine heat to ensure a more stable fuel/air mix.  The O.S. 91HZ Ringed Heli engine is a major player at heli competitions worldwide!
