Notice:

R/C: If you’re controlling this servo with a transmitter, please use the rotation values in the 1100-1900usec column of the table. The rotation amount of a servo depends on the signal range you’re able to send and R/C transmitters transmit a minimum range of 1100-1900, no matter the brand. Keep in mind that transmitters that have adjustable endpoints will allow you to achieve more rotation than what’s listed above.

Robotics: If you are using an Arduino, Raspberry Pi, REV Hub or any controller that allows you to select the PWM range you’re able to send to the servo, please use the rotation values in the 800-2200usec column of the table.

The HSR-M9382TH is the new king of standard size servos! We’ve long awaited a multi-turn servo in a standard size and are giddy about what Hitec has delivered. Check out some of the high-points:

Multi-Turn:
Leading off with the killer feature, it’s multi-turn while retaining position feedback. How many turns, you ask? Up to 7 turns, but as with any servo, the rotation depends on the signal you send to it.  

Programmable:
You can plug the servo in and run it with your servo controller without ever having to worry about programming, but keep in mind what’s on tap:

  • Rotation: The endpoints can be adjusted to increase (or decrease) the amount of rotation available. The max achievable is 7 turns but you can tailor the rotation to exactly what you need.
  • Continuous Mode: If your project requires multi-turns without feedback, toggle to continuous rotation mode and let it spin without bounds in either direction.
  • Speed: The speed of the servo can be adjusted. Max speed is the default, but if your project needs a bit slower movements, plug in and dial it down.
  • Fail-Safe: This feature is a mere safety net but let’s face it, things happen when relying on electronics. Fail-safe allows you to set a position that the servo will go to in the unfortunate case that there’s a signal loss between the servo controller and the servo. 
  • Direction: This servo, like any, is bidirectional but if you want to change the direction it moves when increasing (or decreasing) the PWM signal, you can change the direction with the click of a button.
  • Deadband Width: This setting refers to the position accuracy of the servo. The smaller the deadband, the finer point the servo is looking for. The default setting is 1, which is the most precise. In some cases, such as when running multiple servos on one channel, a wider deadband is preferred so that the servos can work in unison. 
  • Soft Start: If you want the ramp-up from idle to max speed to be slightly lessened, you can adjust the Soft Start from 20% (default) up to 100%. 

All of the above features can be accessed using the Hitec DPC-11 PC interface servo programmer. The programmer will plug into a PC using a USB to mini USB cable. It requires a 6V battery and the BLDC_HSR User interface_Ver 3.1. You cannot program the servo using the default Ver 2.9 software that the DPC-11 ships with.

For those of you less eager to jump into changing parameters with a servo programmer, we’ve created some popular baseline programs that you’re able to have us pre-load onto the servo; just select the row on the table that best fits your project!  The table will give you a general idea of how much rotation you should expect when selecting between the four programming options.  Keep in mind, you may get slightly more rotation than we’ve listed as we don’t know the exact PWM range your servo controller is sending so use the table as a general guide.

Brushless Motor: The servo is driven with a Neo Brushless motor. It delivers unparalleled torque and does so while transmitting low levels of audible noise rather than the screeching that some of us have become accustomed to while using digital servos. Hitec’s brushless motors are able to generate large amounts of torque, and for extended periods of time, without building excessive heat like a digital servo with a brushed motor would.

Encoder: Because the servo is multi-turn, an encoder was used in place of a potentiometer. Encoders are non-contact, therefore you don’t have to worry about the resolution degrading over time in heavy-use applications. Note that since the servo is multi-turn, the positioning feedback is relative rather than absolute.

Titanium Gears: To compliment the torque available, the servo boasts titanium gears for ultimate durability! 

H25T Spline: Hitec has continued their recent trend by using the H25T spline which has won out as the standard within the R/C industry. Furthermore, they used an M3 screw to hold the horn for greater strength and ease of use.
