Hs-55 Servo Economy Sub Micro Univ

Hitec HS-55 Micro Servo (31055S) is an 8g analog micro servo that has been a standard choice for small models for years, built for affordable, reliable performance. It produces 1.1 kg-cm of torque at 4.8V and 1.3 kg-cm at 6V, with transit speeds of 0.17 and 0.14 seconds per 60 degrees respectively, driven by a 3-pole ferrite motor through nylon gears in an engineering plastic case. At 22.8 x 11.6 x 24.0mm it fits micro aircraft, small foamies, park flyers, micro cars and boats, and light auxiliary functions in larger models.
