Hitec's research department and engineers work tirelessly at developing economical servo technology that outperforms the competition and the new HS-40 nano analog servo delivers just that. With a three-pole cored motor and resilient nylon gears, this affordable servo is a dream come true for micro aircraft, sailplane and helicopter pilots. Slightly larger than the popular HS-35HD with an operating range of 4.8 to 6.0 volts, the HS-40 is a solid performer that is easy on your wallet!
