HiTec HS-311 Standard Economy Servo
The HiTec HS-311 is a compact, budget-friendly standard servo motor designed for RC aircraft, helicopters, and robotics applications requiring reliable control surface actuation. Professional hobbyists, roboticists, and educational institutions use this servo for its proven durability and consistent performance in demanding aerial and mechanical systems. This servo solves the critical need for affordable yet dependable angular positioning in applications where cost-per-unit matters without sacrificing operational reliability.
Product Overview
The HiTec HS-311 operates on a pulse-width modulation (PWM) control principle, converting electrical signals into precise mechanical rotation through an internal gear train and feedback potentiometer system. The servo contains a brushed DC motor coupled to a multi-stage gear reduction mechanism that delivers sufficient torque for control surface deflection in RC aircraft while maintaining fast response times. The integrated feedback circuit ensures position holding accuracy within 5 degrees, making it ideal for stabilization tasks where precision matters but extreme accuracy is not critical.
This economy-class servo distinguishes itself through robust construction with metal gears in the final drive stage, providing impact resistance during aggressive maneuvers. The sealed design offers basic environmental protection against dust and moisture common in field operations, while the standard servo case accepts universal mounting brackets used across the RC industry. At its price point, the HS-311 delivers the balance between performance and affordability that makes it the go-to choice for builders prioritizing value without compromising on essential specifications.

- Mechanical Automation Prototypes: General-purpose positioning in DIY automation projects, model engineering demonstrations, and mechanical systems requiring repeatable angular motion
How to Use
Connect the HiTec HS-311 to your RC receiver or microcontroller using the standard three-wire connector: red wire to positive power supply (4.8-6.0V), black wire to ground, and yellow/white signal wire to your PWM control output. Ensure your power supply can deliver sufficient current for all connected servos, typically 500mA per servo during active movement. Program your controller to send standard 1000-2000 microsecond PWM pulses at 50Hz frequency; 1500 microseconds represents the center position, with values below centering the servo counterclockwise and values above centering it clockwise.
Before deploying in your application, perform a range test by commanding the servo through its full travel arc while monitoring for smooth operation and listening for grinding sounds that indicate mechanical issues. Install the servo using appropriate mounting brackets that distribute stress across multiple fastening points, preventing case damage from vibration or impact. For extended field use, periodically inspect the servo connector for corrosion and apply dielectric grease to maintain electrical contact integrity. If the servo exhibits sluggish response or position drift, verify your power supply voltage remains above 4.8V under load, as voltage sag is the primary cause of performance degradation.
Frequently Asked Questions
What is the difference between the HS-311 and higher-end HiTec servo models?
The HS-311 uses all-plastic intermediate gears and analog feedback circuitry, making it suitable for applications where response time under 0.25 seconds is acceptable. Premium models like the HS-5086WP add metal gears throughout, digital feedback systems, and weatherproof sealing, justifying their higher cost for professional-grade applications. The HS-311 remains the optimal choice for budget-conscious builders and educational use where the performance difference is negligible for typical RC and robotics tasks.
Can I operate the HS-311 at voltages higher than 6.0V for increased torque?
Operating beyond 6.0V will damage the internal circuitry and motor windings, voiding warranty and creating fire hazard. The servo is specifically rated for 4.8-6.0V operation; exceeding this range causes accelerated wear and premature failure. If your application requires more torque, select a larger servo model rated for your voltage rather than overpowering the HS-311.
How do I troubleshoot a servo that twitches or jitters during operation?
Twitching typically indicates insufficient power supply capacity or excessive electrical noise. Verify your battery voltage remains above 4.8V under load using a multimeter, and install a 100uF capacitor directly across the servo power pins to filter noise spikes. If using a long servo lead, move the servo closer to the receiver to reduce signal wire length. Ensure your RC receiver is properly grounded to the battery negative terminal, completing the signal reference circuit.
