Overview
The MKS HV747 Titanium Gear High Torque Servo Motor with aluminum case is a high-voltage, high-speed servo designed for demanding glider, airplane and jet tail applications. This precision servo motor delivers strong stall torque, fast response, and durable metal gearing, and was used by Mr. O to achieve a 24.58 s world record at the 2013 FAI-F3F World Cup.
Key Features
- High-voltage operation for direct use with 2S LiPo power systems (within specified voltage range).
- 12 x 20 mm coreless motor for high efficiency and durability.
- 9 mm VR, ultra high-resolution position control.
- Chrome-titanium metal alloy gear train for strength and wear resistance.
- Unique gear structure with very low backlash for precise control.
- Aluminum case for improved heat dissipation and rigidity.
- Dual ball bearings for smooth, low-friction output.
- Compact case size suitable for high-performance gliders, airplanes and jets.
