Hitec HSB9381TH Brushless High Voltage (HV) Ultra Torque Servo
Brand: Hitec
Part No: 2220881
Shadow Stock: Usually ships next day
The Hitec HSB9381TH Brushless High Voltage (HV) Ultra Torque Servo (part number 2220881) pairs an ultra-efficient Neu-Castle brushless motor with a titanium gear train in a full metal case. Designed for discerning pilots and racers, it delivers constant output across 6.0–8.4V while keeping current draw extremely low. A programmable 12-bit digital circuit allows fine tuning via Hitec’s PC interface, and water and dust resistance adds durability in demanding environments.
Key Features
- Industry-leading titanium gear train with dual ball bearings
- Neu-Castle brushless motor with MOSFET drive
- Constant power output across 6.0–8.4V
- Programmable 12-bit resolution digital circuit (via Hitec PC interface)
- Ultra low current consumption; energy efficient
- Hybrid MPD (metal–plastic–duralumin) 1st gear
- Ultra hardness gear shaft with 3 axial metal bushings
- Full metal case with motor heat sink
- Power Absorbing Device (PAD) to help prevent current backflow
- Water and dust resistance
- Standard 25-tooth spline
Brushless Servo Technology
Hitec’s BLDC architecture maintains consistent output regardless of input voltage within the HV range, supporting precise control from start to finish. The programmable digital amplifier enables custom setup to match a wide range of demanding applications.
The hybrid MPD first gear combines metal, plastic and duralumin for performance and durability while reducing the chance of inadvertent electrical contact with model hardware. Energy-efficient design targets significantly reduced power draw compared with earlier brushless servos, with PAD helping protect connected electronics.
Tech Specs

- Constant Power Output
- Programmable 12-Bit Resolution Digital Circuit
- Low Current Consumption
- Energy Efficient
Regardless of your power input (6.0V - 8.4V), Hitec's brushless servos will maintain constant output power throughout your flight or racing.
BLDC Servos Programmable Digital CircuitYou can utilise Hitec's PC interface to customise your brushless servos to maximise your performance in a multitude of applications.
Hybrid MPD (Metal-Plastic-Duralumin) 1st GearThe metal, plastic and duralumin hybrid 1st gear gives our brushless servos maximum performance and durability even in the touchest applications. The plastic within the MPD prevents inadvertent electrical contact with the aircraft or vehicle's hardware.
Ultra Low Current Consumption'Energy efficiency' is a common interest for all modelers. By designing servos which consume only 1/5th of the power of existing brushless servos, Hitec engineers have successfully achieved low power consumption and our goal for combining efficiency and dynamics in a brushless servo technology.
PADThe Power Absorbing Device prevents the backflow of current to devices that cannot accept it.
