This is the ProTek R/C 155S Digital Hi-Speed 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 the competition can provide, ProTek R/C servos deliver performance and unmatched value, with industry leading customer support.
The ProTek R/C 155S High Voltage Hi-Speed servo delivers lighting fast 0.08 transit speed and 308 oz-in of torque at 6.0V, and when you bump the voltage to 7.4 the spec's increase to 0.06 and 370 oz-in! Spec's like these make this servo an excellent choice for any 1/10 to 1/8 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 200mm long 22awg connector wire with gold plated connectors, a coreless motor and a Conformal Coated circuit boad.
Plus, instead of a cheap plastic servo horn, 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. 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.
Conformal Coated Circuit Board
The ProTek R/C 155 series is the first to introduce the use of a Conformal Coating: a thin layer of polymeric film that contours to the printed circuit board to protect against vibrations, moisture, dust, chemicals and extreme temperatures. With the application of Conformal Coating, the 155 series is ready for battle.
Warning! This ProTek R/C servo requires that you use a m3x10mm screw to attach the servo horn to the output shaft. If you choose to use another screw, be sure to use a 10mm length screw. Use of a shorter screw can cause failure and will void your warranty.

There was an instance where the servo was not performing properly so I had to remove it and send it to Amain to have it diagnosed. They did diagnostics on it and could not
duplicate what I had experienced. But Amain being the company that I've known them to be, sent me a new replacement without hesitation. I was so happy with the performance
of the servo and the customer service of Amain, and decided to order (3) more of their servos to power both 1/8 nitro on road cars that I own.
I was hoping it would have interchangeable servo leads to change length of wire like other protek servos. No such luck here.
