This is the ProTek R/C 140T Low Profile Digital “High Torque” Metal Gear High Voltage Servo. ProTek R/C Servos have been developed to provide enthusiasts with high quality servo’s that will exceed expectations at every level. With features that meet or surpass what our competition can provide, ProTek R/C servos deliver performance and unmatched value, with industry leading customer support.
The ProTek R/C 140T High Voltage Low Profile servo delivers an impressive 185 oz-in of torque and 0.10 transit speed at 6.0V, and when you bump the voltage to 7.4V the spec’s increase to 215 oz-in and 0.08 transit speed! This servo does not stop there, when cranked up to 8.4V you can see 230 oz-in and 0.07 transit speed. These specs make for an excellent choice for 1/12 or 1/10 scale RC vehicles. Other features include a plastic case with an aluminum center band for heat dissipation, a metal gear train with dual ball bearings, 160mm long 22awg connector wire and a coreless motor.
As most 1/12 or 1/10 scale vehicles come with, or require, a specific servo horn, this servo comes ready to be equipped with a servo horn of your needing (Not included). Stop wasting your money on budget servos that look good in the spec list, but fall short when its time to perform. Get ProTek and don’t look back.
