Hitec high torque HS-985MG Coreless Motor Servo was designed for larger high performance aircraft or on/off road vehicles. Featuring
excellent resolution and centering, the newer HS-985MG replaces the
older and now discontinued HS-945MG. Offered with an improved case top
with two brass axial bushings for greater strength and stability to
insure a long life and smooth rotation.
Note: 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.
