Associated XP Digital DS1313 servo with coreless motor has metal gears. Coreless motor offers smooth operation and faster response time. Aluminum heat sink dissipates heat build-up for fade free performance. Water and dust resistant. This package includes Associated XP Digital DS1313 Servo with JR type connector, 1.7" (44mm) long double servo arm and mounting hardware.For best performance use only an FM radio system and high capacity 6V NiCd or NiMH batteries. 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 and faster response time.
