HS-7115TH Servo

The HS-7115TH will fulfill every pilot's dream when it comes to flying slim-wing aircraft. With its efficient, powerful three pole, metal-brushed motor and mighty titanium gear train, this servo brings the ultimate in high performance to your sailplanes, pylon racers and smaller scale models. The extremely thin, 8mm case with included mounting bracket allows it to fit into the tightest wings and most compact spaces. Constructed with dual ball bearings, the high voltage HS-7115TH provides an impressive 50 oz-in of torque at 7.4 volts.

Stock:

With an Average Radio System:
72°
Your average transmitter and receiver will output a relativly narrow PWM signal range.

Radio System + Servo Stretcher:
119°
Adding a Servo Stretcher to your radio system setup will allow you to achieve wide PWM signal ranges.

Wide Signal Controllers:
119°
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:
117°
Your average transmitter and receiver will output a relativly narrow PWM signal range.

Radio System + Servo Stretcher:
197°
Adding a Servo Stretcher to your radio system setup will allow you to achieve wide PWM signal ranges.

Wide Signal Controllers:
197°
Controllers such as the Actobotics® Servo Controller, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
