*Digital servos do not need to be programmed to operate. They work great right out of the box and purchasing a programmer is not necessary.

Standard Servo Schematic 2

The digital wave is now sweeping across the servo world and Hitec is leading the way. The HS-5485HB is Hitec’s second digital standard servo. Adding the digital component to the already great HS-485HB means that the
HS-5485HB is even better. The torque numbers and speed are enhanced from the HS-485HB. The standing torque is nearly 5 times better and the precision has been increased. Being digital means the motor now receives the position signal 300 times per second rather than 30 times per second. This servo can also be programmed using our hand-held servo programmer. Need the servo to travel up to 180° no problem! Need to slow the servo down, no problem! You can do just about anything with Hitec digital servos in combination with the programmer.
Note: The HS-5485HB servo spline is slightly oversized and will be a very snug fit into broached servo accessories. After installed the first time, later assembly will be easier.

Karbonite Spline

The HS-5485HB incorporates strong Karbonite gears and 24T output spline

This servo can be configured to operate 180° by using any of the following servo programmers:
Hitec HFP-25, HPP-21, HPP-21+
