This is the ProTek R/C 170S "Chad Bradley Team Edition - High Speed" Digital Servo. Chad Bradley is a legend in the world of R/C. A multiple time IFMAR 1/8 off road World Championship finalist with countless big race wins under his belt, Chad is one of our most respected and decorated drivers. That's why we collaborated with Chad to develop the 170S Team Edition. The 170S Team Edition delivers the rapid, high speed response that ProTek R/C team drivers demand, combined with the quality, reliability and customer support that our customers demand from ProTek R/C. 

  • “I have been testing the 170 series of servos for some time now. The torque, holding power and speed of these servos are insane! 1/8 Off-Road is the ultimate test for any servo, and the 170 series servos give me the power and precision I need to hold the tightest lines around the most demanding tracks. I have never used a servo that performs as good as these and I wont use anything other than ProTek 170 series servos. If they weren't up to my standards, I wouldn't put my name on them." - Chad Bradley, ProTek R/C Team Driver 

At 6.0V the ProTek R/C 170S Chad Bradley Team Edition High Speed servo delivers 0.09 transit speed, with an incredible 445 oz-in of torque. When you push the voltage to 7.4, the spec's jump to 0.07 and 549 oz-in! Spec's like these make this servo an excellent choice for any 1/10 to 1/8 scale application that can benefit from lightning fast transit speeds. A black anodized aluminum case with gold accents provides a striking appearance that sets it apart from any other servo on the market, while at the same time providing bomb proof durability and efficient heat dissipation. Other features include a durable metal gear train supported by dual ball bearings for smooth and precise rotation, 190mm long 22awg connector wire with gold plated connectors, and a coreless motor.

Plus, instead of a cheap plastic servo horn, ProTek R/C goes the extra mile with an included aluminum clamping 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.

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.

I purchased the protek 170S for my Axile Wraith, I rock race with the Wraith and on our clubs track there are very tight turns and I also have a on chassis servo with a pan hard bar, which makes the need for monster torque a must. I have only run it for 3 races now but so far I am extremely happy with the servo! I can't say how it will do in the long run but if it continues to proform this well over the long haul I will be happy as heck. My only dislike would be I wish it was a bit faster but speed and torque are a trade off.

best servos out there… in the past i run futaba, kopropo, hitec, savor… this are the ones i liked the most… and they just lasssssst...
Got this for my truggy steering and this is unreal. I'm running 6v and that is more than enough yet awesome to know if I want to invest in 7.2v power source it will be out of this world. Best servo I have owned. Protek is starting to become THE NAME in servos.

These new servos are blistering fast. Almost too fast when set up with a 7.4 lipo. Not only are they fast, but they are strong too. You can count on finishing your race when using these new servos.

Loves these new servos from ProTek! High speed and massive torque make them perfect for all my RC vehicles. The new case and included hardware look fantastic.

Installed this as a steering servo in my RC8T. Worked awesome; for about 30 seconds then the servo went crazy, started jittering and stopped working. Doesn't work at all now. Plugged in a different servo and I have steering again. Not what I expected from this product. Now I gotta go through this return process...

Just installed this to my losi 3.0 as steering, 7.4v. All metal casing. Neat finishing. I spray plastidip & pack the bearing with grease to make it w/proof. Found a little bit heavier than savox. Its fast & with monsteruous torque. Now i need to tighten the servo saver to take advantage of the torque offered. Love it and worth the money spent. Thinking to replace the savox throttle servo with this 170s soon.
