This is not dustproof as is the S9304, thus is not suggested for cars and trucks. This is not a requirement for servos used in planes. This product includes, one S9202 Coreless servo with 2 Ball Bearings and one Accessory Bag (mounting hardware and horns). A note on Coreless motors. A conventional servo motor has a steel core armature wrapped with 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 is much lighter resulting in smoother operation and faster response time.
