Compact Control SolutionEconomical micro servo for hobbyists
The HS-81 Standard Micro Analog Servo offers an exceptional combination of speed, torque, and lightweight engineering for small RC airplanes, gliders, and light RC vehicles. Designed by Hitec as an economical yet reliable actuator, this micro servo delivers responsive control surface movement without adding excessive weight.
Proven Hobby PerformanceReliable analog control for builds
Engineered for modelers who demand dependable performance on a budget, the HS-81 Standard Micro Analog Servo features a durable nylon resin gear train driven by a strong 3-pole ferrite motor. Operating seamlessly within a standard 4.8V to 6.0V range, it delivers up to 41.66 oz-in of torque and rapid transit times down to 0.09 seconds. Whether you are building a lightweight park flyer or configuring precision steering on small scale models, this Hitec analog servo provides smooth, consistent actuation. Note that this model features high-strength standard resin gears rather than metal gears, making it an optimal, cost-effective choice for low-impact RC applications.
