D940TW Servo-Clockwise (stock)-Stock Rotation
SKU:
The titanium gear D-940TW is part of Hitec’s D-Series dynamo servo line. All Hitec D-Series servos have been designed using their cutting edge, custom engineering. Combining industry leading high-resolution, state-of-the-art ultra-response technology with a 32-bit MCU, and a 12-bit ADC for unprecedented programmability and flexibility. These servos deliver significantly smoother movement. The speedy, powerful line operates on a wide 4.8 ~ 8.4 voltage range, allowing use with any common battery chemistry without the need for adapters or regulators. Featuring Hitec’s industry standard 25-tooth output spline with an M3 pan head with a phillips drive style, each D-Series servo brings monster performance never known before in the market.
How Far Will This Servo Rotate?
The answer to this question is partially dependent on what you are using to control the servo.
Click for a quick video explanation.
With an Average Radio System:
72°
Your average transmitter and receiver will output a relatively narrow PWM signal range.
Radio System + Travel Tuner:
120°
Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges.
Wide Signal Controllers:
120°
Controllers such as the Servo Commander, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
