HS-7235MH Servo

The HS-7235MH servo delivers exceptional speed and torque in a compact package. Built with an efficient coreless motor optimized for 7.4V operation and heavy-duty metal gear train with dual ball bearings, this high-end mini servo delivers unbridled performance, as does its brother, the HS-7245MH. Whether you are flying mid-size gas and electric airplanes, 500-550 electric helis, or driving 1/12th scale on-road racers and 1/18th scale rock crawlers, the lightning speed of this servo will make you the master of your RC domain.

Stock:

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

Radio System + Travel Tuner:
121°
Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges.

Wide Signal Controllers:
121°
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:
119°
Your average transmitter and receiver will output a relativly narrow PWM signal range.

Radio System + Travel Tuner:
199°
Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges.

Wide Signal Controllers:
199°
Controllers such as the Actobotics® Servo Controller, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
