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 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.
This servo is rated as high-torque for helicopter gyro applications, the rating would not be considered high-torque for airplane control surface or monster truck steering applications.
