Servos for rock racing? Hey everyone what servos are you running for steering? I'm in the process of looking for a servo for my wraith and twin hammers. I do not really care for the best because the best costs a lot and do not want to spend a lot unless thats the only option. Something with pretty good torque and speed but the main thing I want is for it to last a while. A servo that does not get a ton of play after a couple of races would be nice. :lmao: Thanx in advance |
Re: Servos for rock racing? HiTec is really a good brand, yes it is expensive(relative), but even builders like HH are having teething problems (Turnigy 910, included), if you want to experiment with trying to find the best servo for the price then there are alot of options and even if they are only 20-30 $ each (Solar, etc.). I am sure some will last, but under the grueling conditions of rock racing and the inevitability of it getting hit (impact/shots to the servo/impacts to the arm, etc.), they won't last. Anyway after 3 servo's @ $30ea, your there 7954. Look at all the servos at the next race, take a count of what is out there, I bet 1-2 Futaba, maybe a HH, but a majority Hitec. IMO.... |
Re: Servos for rock racing? Just spend the money......:lmao: |
Re: Servos for rock racing? Ti gear Hitec for the win! |
Re: Servos for rock racing? So 7954 is the one to get? |
Re: Servos for rock racing? I run the 7940 in the Beast.... |

Re: Servos for rock racing? Also the "new" 8380th....the new one I am trying out....specs; HS-8380TH @6V= .15sec/60' 402.73oz-in @7.4V= .13sec/60' 486.05oz-in Servo Weight: 2.4oz Dimensions: 40 x 20 x 38mm (standard size) I think i heard that the motors are BL in the servo and thats why they can perform so well and yet don't need HV. Not sure on that one though....he said she said. But the specs above are from the back of the packaging from the servo container. |
Re: Servos for rock racing? Hitec 7950 in IMO, but honestly, no matter what servo you run, you hit it hard enough the wrong way, its gonna break! Ive gone through 3 $100+ servos in 8 race events, my advice, PROTECT YOUR SERVO the best way possible AND drive better! Good luck! |
Re: Servos for rock racing? I use the solar d772. I am on my 2nd one from running both u4rc series. |

Re: Servos for rock racing? I've been trying to figure out how to make a servo saver for a 4 link setup...no luck yet. |
Re: Servos for rock racing? I've been running the same Futaba BLS157v in my Wraith for almost 2 years. My truck is light now, but it was 6.5lbs for the first year. Like everyone else has said, spend the money! Breaking a bunch of $30 servos adds up fast. |

You think either of those will last with plastic splines? These rigs take a beating on track, not just a couple jumps here and there lol |

I've been trying to think up a way to put heavy springs inside of a tie rod, so the steering will still work on the rocks, but in heavy hits like cartwheels, etc. the springs will take some of the hit of the servo gears... it would most likely only need 1/4-1/2 in. of travel or so to be effective. |
Savox 1230. Steel gears, 500oz of torque. 6V. Unlike the 7954 & 7955 it doesn't have a weak link "carbonite" gear that will strip and ruin the brass motor output gear. Yes the titanium gear set still uses the carbonite gear making the Ti aspect nothing more then a marketing gimmick. I've owned two and have been disappointed. If you need something slightly faster give the savox 1231 a try. I put 14 hours of run time on both of mine almost every weekend. Take it for what it's worth. Look through my build threads below for information on hitec and savox servos torn apart, waterproofing aspects, stripped gears etc. I'm not a fanboi, I seek function and durability. |
