COMMENTS

Use with NiCD batteries only

A note on Coreless motors: Conventional servo motors have a steel core armature wrapped with wire that spins inside the magnets. In a Coreless design, the armature uses a thin wire mesh that forms a cup that spins around the outside of the magnet eliminating the heavy steel core. This design results in smoother operation andfaster response time.
