I prefer the Hitec 7955. Its a great servo will cost you around $120 bucks has 333 inch oz of torque at 6 volts. You can find them cheaper around $100 and used for around 70 to 75. I prefer Hitec because their customer service is top notch. They will replace or fix your servo no questions asked. I know some people whose servos were not even under waranty and they got them fixed for free. The only down fall is that through the peak season during the summer their turn around is a little slow but usually not more than 2 or 3 weeks. Most of the time though its about 2 weeks. In the spring and fall and through the winter though it only takes about a week. Buy a good servo now. Don't buy a cheap one first. you will end up replacing it anyway. Just spend the extra money and get a good one. Also you can pick up a servo programmer for them for around 25 bucks that I highly recommend. You can set the voltage cutoff and end points as well as a lot of other things for their digital servos.

Hitech TG is probably best bet for your money, we have them at our shop for 109.99 I think, but same for the JR 9100T, the JR has bit more Torque. We've had good luck with both of them though. A good servo has a lot of Torque, at least for a rock crawler application. The more torque, the better the wheels turn when you're in a bind. For a good comp setup, you want more then 300 oz for sure. However, no servo is completely "bullet proof" and proper EPA (steering end point adjustments) are still required. So if your TX doesn't have EPA settings, upgrade that first or you'll very likely fry your new $100 servo. RTR radios generally don't have EPA settings. Good Luck |

For $119.99 you could get a 423 Oz/Inch @ 6v. the Airtronics 94780. For the money it's the best performance you can get. I have seen them going for $109.99. |

The hobbico c170 is pretty much a rebranded 7955 for $90. The JR 8711 is a real 400+ for $140. I got a nice used 8711 for $65 and it put a big smile on my face |

+1 on the Hobbico CS170, I have one in each my crawlers. at 333oz and $90, it is more than enough for my Berg and 16oz wheels, and doesn't need a seperate BEC. I do run dual speedos which does boost the current ability to the RX. Most of the JR's I've seen seem to develop a stutter after about 10 months, I've seen this on 3 seperate rigs. |

| The CS-170 is a rebranded 5955tg, the older version of the 7955. The newer 7955 is supposed to be quicker but also heavier than the 5955tg or the hobbico version.

I have a newbie question. I am running a 11.1 volt battery and most servos say 6 volts do I have to find a servo that works with the 11.1 volts?

| Re: whats the best servo and why?
Are you trying to power it directly from said battery? If so, then yes, you'll need a servo capable of running 12.6v (fully charged 3s) or it will die a fiery death. Most here run their servo's from a Battery Elimination Circuit (BEC) either one built in to the Electronic Speed Controller (ESC) or one wired externally like Castle Creation's 10amp BEC. Most ESC's BEC's have a fixed voltage (could be 4.8v, 5v, or 6v) but some can be adjusted (Hobbywing's WP1080 has 6v and 7.4v, Castle's Mamba X is also adjustable.) Castle's external BEC can be adjusted in 0.1v increments. If your servo is only plugged into your receiver, it's getting its power from the ESC's BEC and you can test its voltage (or tell us what ESC you have) very easily with a multi meter. Most ESC's can't supply enough amperage for very high torque servos, which is why many (most?) people run an external BEC. If you'd prefer to power a 6v servo from a separate battery, you can get 6v and 6.6v "receiver pack" that you just plug into your receiver, just be sure to pull the power wire out of your ESC's receiver connector if you go this route, so you don't feed more voltage to it. That's the way all the nitro/gas rc's run anyway. |

Holmes Hobbies sells the SHV500v2 servo that is designed to be run directly from your 3S or 4S LiPo (11.1v or 14v)... Information below is quoted directly from the Holmes Hobbies website: https://holmeshobbies.com/electronic...0v2-servo.html Torque @ 11.1v: 32.4 kg/cm (450 oz/inch) Speed @ 11.1v: 0.10 sec Torque @ 14v: 37.5 kg/cm (520 oz/inch) Speed @ 14v: 0.08 sec The BLS SHV500v2 servo is designed for R/C Rock Crawlers, but at home in any vehicle that needs high torque with fast speeds. It can be powered directly from a 2s to 4s lipo battery, eliminating the need for an external BEC! Clean up your wiring, gain space in a tight rig, and enjoy silent performance from the high quality brushless motor and circuitry. FEATURES: Water-Resistant Alloy Case with O-Ring Seals All Metal machined gears with improved pin strength Upgraded Brushless Super motor with 200C rated magnets 24cm radio signal lead 24cm 12v power lead with female JST plug, includes male extension 2s through 4s Lipo compatible 1 Year Warranty |

Turnigy 959v1 or v2 are probably the strongest servos on the market. https://www.youtube.com/watch?v=7zylqOIHdKA That vid is a great test that shows the power of a bunch of big name servos. I run PowerHD 20kg servos and love them. |

I wouldn't call Turnigy and PowerHD big names.... But would be curious for him to throw on a Holmes SHV500, Savox 2290, and Protek 370TBL on that test rig. | |

These old threads are like the Energizer bunny they just keep going and going. That said, I like my Savox SA 1230SG Specifications: Torque @ 6v - 36.0kg/499.9oz-in Speed @ 6v - 0.16 sec/60 deg Dimensions L x W x H (mm): 40.3 x 20.2 x 44.9 Weight: 79.0g Last edited by Inspector86; 05-10-2018 at 11:35 AM. |

| Re: whats the best servo and why? What I liked about the video is it showed how the servos actually perform, not what stats they list in their descriptions hehe. A lot of claims are made that never actually play out in real life performance.
