Hitec HS-81 Standard Micro Servo

Description

Hitec’s research department and engineers work tirelessly to develop inexpensive, high-quality servo technology. This is particularly true of the Hitec HS-81 analog servo, with its three-pole brush motor and elastic nylon gears. Slightly larger than the popular HS-55 with a working range of 4.8 to 6.0 volts.

The HS-81 impresses with its good price-performance ratio
