COMMENTS

This servo can be programmed with any Hitec digital servo
programmer. However, the Overload Protection and Resolution High/
Low can only be programmed with the HFP-20, HPP-21
(HRCM4420) or the HPP-21+ (HRCM4421)

A note on coreless motors-a conventional servo motor has a steel core
armature wrapped with wire that spins inside the magnets. In a
Coreless design, the armature uses a wire mesh that forms a cup
that spins around the outside of the magnet. This arrangement is
much lighter resulting in smoother operation and faster response
time.
