HSB-9485SH Servo

Pro level hobbyists demand the power and precision found in Hitec's triple threat HSB-94XX servos. Each one is designed with their durable steel gears and impressive Neu brushless motors with the HSB-9485SH bringing immense torque.

How Far Will This Servo Rotate?

The answer to this question is partially dependant on what you are using to control the servo.

Stock:

With an Average Radio System:
67°
Your average transmitter and receiver will output a relativly narrow PWM signal range.

Radio System + Servo Stretcher:
120°
Adding a Servo Stretcher to your radio system setup will allow you to achieve wide PWM signal ranges.

Wide Signal Controllers:
120°
Controllers such as the Actobotics® Servo Controller, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.

Reprogrammed:

Whether you purchase the reprogrammed option or get a servo programmer and do it yourself, a reprogrammed version of this servo will be able to achieve greater travel than it can in stock form.

With an Average Radio System:
114°
Your average transmitter and receiver will output a relativly narrow PWM signal range.

Radio System + Servo Stretcher:
203°
Adding a Servo Stretcher to your radio system setup will allow you to achieve wide PWM signal ranges.

Wide Signal Controllers:
203°
Controllers such as the Actobotics® Servo Controller, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.

Special Features

- Constant torque output: Revolutionary circuit and motor designs allow the HSB-9XXX Series servos to maintain their speed in a more consistent manner, regardless of load.
- Hybrid MPD 1st Gear: Unique ultra-durable Metal/Plastic/duralumin hybrid first gear prevents inadvertent electrical noise from affecting other components within your aircraft or vehicle
- Custom NeuMotor: Designed by Steve Neu exclusively for the HSB-9XXX Series, these high performance, brushless motors provide long-standing durability and performance.

Brushless Advantages

- At least FIVE TIMES longer-lasting than brushed servos.
- 30% faster response times.
- Greater resistance to jolts and vibration.
- Smoother operation.
- Same power consumption as brushed digital servos.
- Same compact case size as standard servos.
- Exceptionally durable geartrain.
- Smooth dual ball bearings

PLEASE NOTE

While compatible with most radio control devices, the regenerative braking feature of the HSB-93XX series servos may cause a problem if the device cannot accept a backflow of current. The types of devices that cannot accept this backflow are: Voltage Regulators, Power Safe Receivers and certain BEC circuits whether stand alone or integrated within an Electronic Speed Control. Check with the manufacturer or the Hitec website for a list of compatible models. If your device cannot accept a current backflow, then you must install a PAD (Power Absorbing Device - Hitec PN# 55756) as described in the manual. A PAD is included with every Hitec brushless servo.
