A proven powerhouse...made better!

The 91HZ Ringed Heli Engine is a major player at heli competitions worldwide, and this newest version takes 3D performance to another level!

The redesigned regulator is positioned horizontally, working with the PD-08 fuel pump it delivers a steady supply of fuel regardless of the helicopters attitude or demand on the engine.
The piston and crankshaft are designed to reduce vibration and improve torque over the entire rpm range.
The narrow profile of the heat sink head helps the 91HZ fit completely inside cooling shrouds without cutting or losing cooling power,and a thermo insulator on the 61B-PII carburetor blocks engine heat to ensure a stable fuel/air mix.
Includes in-flight needle value adjustment arm.
