The ProTek R/C 160SS High Voltage Low Profile servo delivers 127 oz-in of torque and 0.05 transit speed at 6.0V, and when you bump the voltage to 7.4 the spec's increase to 152 oz-in and 0.04! Spec's like these make this servo an excellent choice for any 1/12 to 1/10 scale vehicle application. Other features include a full aluminum case that provides bomb proof durability and improved heat dissipation, a metal gear train that is supported by dual ball bearings, a 160mm long 22awg connector wire with gold plated connectors, and a coreless motor.Plus, ProTek R/C goes the extra mile with an included aluminum single arm servo horn that will stand up to a majority of the punishment you can throw at it. And for additional rigidity, four blue aluminum servo ear guides are included as alternatives to the rubber grommets.Features:Low-Profile case saves space and weightIdeal for any 1/12 to 1/10 scale vehicle applicationFull aluminum caseHigh voltage circuitry0.05 transit speed, and 127 oz-in of torque @ 6.0V0.04 transit speed, and 152 oz-in of torque @ 7.4VAluminum single arm servo hornFull metal gears and dual ball bearings160mm long 22awg connector wire w/gold plated connectorsCoreless motorRecommended Application 1/12 to 1/10 scale SurfaceOperating Voltage 4.8V - 7.4VOperating Temperature: 14 to 140 F (-10 to +60 C)Operating Speed @ 6.0V: 0.05/60 secOperating Speed @ 7.4V: 04/60 secDynamic Torque @ 6.0V: 127 oz-in (9.1 kg-cm)Dynamic Torque @ 7.4V: 152 oz-in (11 kg-cm)Motor Type: High Efficiency Coreless MotorOutput Shaft: 25 ToothGears: MetalWeight: 54.5gPulse/Frequency: 1520 / 333hz
