Manuals & SupportState-of-the-art power for serious heli pilots!
The 55HZ-R DRS Ringed delivers state-of-the-art power for serious heli pilots! It includes the Demand Regulator System for outstanding run consistency and a built-in mount for Futaba GY701 and CGY750 rpm sensors. Two needles on the included 40-LR carb let pilots precisely adjust middle and high speeds.
- Includes: #8 plug, 40-LR carb & check valve.
- 2-year limited Hobby Services warranty.
- 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 an rpm sensor for the Futaba® GY-701 governor or CGY750 gyro, ensuring precise rpm control.
