The HS-81 is among our most popular servos. Available in both resin and metal gear versions. With a fine balance between speed and torque, the HS-81’s were designed to be both economical and reliable. They are perfect for small electric aircraft as well as throttle servos on gas aircraft. By utilizing the standard size Hitec spline, any horn or arm that fits on a standard Hitec servo will fit on the HS-81.
This servo can operate 180° when given a pulse signal ranging from 600usec to 2400usec. Since most R/C controllers cannot generate this wide of signal range, you will need to use our servo stretcher for 180° operation.
