One HS-425BBS Servo
One Servo Accessory Bag (grommets, screws, bushings, horns)
Length: 41mm (1.6") Weight: 45.5 (1.60oz)

Height: 36.5mm (1.4") Torque: 45.9 oz-in
This servo shares the same case with the HS-300 servos. The biggest
difference is that this servo has dual ball bearings, making it
faster, with more torque, and less slop.
