This is the Futaba S9650 Digital Mini Servo with two ball bearings for helicopter and airplane use and comes with "J" connector pre-installed. Precision fixed-wing and helicopter flying requires precise, high-tech servos, and we are answering the call with new digital servos that reach full power immediately. They feature high-capacity, high-current wire for low resistance while maintaining standard servo dimensions and light weight so you can mount them almost anywhere.

Features:

• This servo has a Coreless motor. Conventional servo motors have a steel core armature wrapped with wire that spins inside magnets. In a coreless design the armature uses a wire mesh that forms a cup that spins around the outside of a magnet. This arrangement is much lighter, which results in smoother operation and faster response time.
• Nylon gears.
• Can be used with 1/12 or 1/18 scale vehicles and electric helicopters.
• One year manufacturer warranty.

Specs:

• Length: 43mm between centers of side mounting holes, 35.5mm servo body length, 42.5mm between the centers of standard mounting holes
• Width: 15mm
• Height: 28.6mm
• Weight: 0.9oz (26g)
• SPEED: .14 sec/60° @ 4.8V, .11 sec/60° @ 6.0V
• TORQUE: 3.6 kg-cm @ 4.8V (50 oz-in @ 4.8V), 4.5 kg-cm @ 6.0V (62.5 oz-in @ 6.0V)
