The 55HZ-R DRS engine is designed to meet the unique demands of F3C competition and 3D flight!
- The Demand Regulator System (DRS) uses pressure to consistently deliver the optimal air-fuel mixture to the engine — regardless of the heli's attitude
- Two needles on the carburetor precisely adjust middle and high speeds
- A hole in the cover plate allows for mounting a sensor of Futaba®'s GY-701 governor, to insure more stable flight
- Cranks out 2,000-20,000 rpm
