HS-7245MH Servo
Hitec’s high voltage and high torque HS-7245MH delivers exceptional speed and torque in a compact package. Built with an efficient core-less motor optimized for 7.4V operation and heavy-duty metal gear train with dual ball bearings, this high-end mini servo provides unbridled performance! Whether you’re flying mid-size gas and electric airplanes, 500-550 electric helis, or driving 1/12th scale on-road racer and 1/18th scale rock crawlers, the lightning speed and full-size muscle of this servo will make you the master of the RC domain!
How Far Will This Servo Rotate?
The answer to this question is partially dependent on what you are using to control the servo.

Stock:
With an Average Radio System:
72°
Your average transmitter and receiver will output a relatively 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 Servo Commander, 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 relatively 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 Servo Commander, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
