This is the ProTek R/C 150S 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 our competition can provide, ProTek R/C servos deliver performance and unmatched value, with industry leading customer support.

The ProTek R/C 150S High Voltage Hi-Speed servo delivers lighting fast 0.08 transit speed and 281 oz-in of torque at 6.0V, and when you bump the voltage to 7.4 the spec's increase to 0.06 and 346 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, and a coreless motor.

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.

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.

A+++++++++++ Awesome servo for the price you cant really beat it, its all aluminum, faster, more torque and cheaper then other high end brands. my only thing is i wish they would back up there product with a better warranty, this is the only problem im having. They should back up their product like Savox does, breaks anytime anywhere, just send it in or to a local hobby shop and they will swap it out. a local racer liked them so much and wanted some but after i told him Savox has that warranty he said he would rather go with them. Please change your policy cause i would buy these for all my cars and more people would use them.

The Protek 150s is the servo I feel to be the best in my 1/10 electric off road buggies and short course trucks (2wd and 4wd). the 150s has plenty of speed, torque and holding power for the large short course tires.

Specs looked good, price looked good, thought I'd give it a try. Holy moly!!! Never had an issue after more than a year in a heavily abused ebuggy. I'll be buying more for my nitro car. Can't go wrong with these.

Best servo for the money. Bought 2 of them for my nitro buggy, this are my first "affordable" servos, always owned brand name servos, I have been a Futaba HV servos follower for a long time, and orion servos for my 1/10 cars, this servos are just as smooth as the futabas, but affordable.

I ran this servo for the first time today. It worked flawlessly & is the fastest servo I've ever run. Just make sure to use thread lock on the screw holding down the servo arm.

I put this bad boy in my 22 and the performance has been nothing short of AWESOME...the only drawback, is now I need to fork over the cash and get one for my B44!

This is the only servo I will ever buy. I have this servo in my Mugen 1/8 buggy ECO. It's super fast and has plenty of power. I'm not sure you even need the high torgue 150S. I'm most likely going to put two of these in my MBX7. I have the Hitec titianinum gear servo and it's very noisy. This servo looks awesome and comes with an aluminium can't beat it!

Very fast and powerful servos, we use these for our throttle/brake in our buggy and truggy
