So I am getting ready to get back into rock crawling and what not. And my question is what should I be looking for a servo?? Its going in my project Silverado. Nothing fancy.I don't know much about them so any and all info would be great thanks.

Also how about speed controls? Whats good now a days

Well i would definitely go for metal gears, and something around 80oz of torque or more if you want a reliable servo that can steer the wheels well. OR you can always just get a cheaper servo around 40oz of torque with plastic gears, i would honestly recommend the hitec HS-625MG or the HS-645MG they are nice servos that are cheap enough ($35-$40). OR if you want waterproof there is the traxxas servo with 80oz of torque for about $14 (no servo horns included) that i saw at my hobby shop, not sure if the gears are metal though.

if this a servo for steering - I have JR 8711 which works well and I also have a Hitec 7955tg that is also real good. I would recommend Both. They are in the 330 oz torque range which should give you plenty of power steering on the rocks. I beleive airtronics makes a high torque one too but have never used it. Hope this helps.

As far as ESC's I have a castle mamba max which works well. The Tekin FXR is a bit cheaper and from what I hear has an awesome drag brake.

You asked some of this in another thread but : Novak Rooster Crawler & the traxxas 2075 for bashing.

03ssilverado · 09-29-2009, 05:26 PM

yeah that was the question I was going to ask but said servos instead

Thanks for the info guys

jlast · 09-29-2009, 07:22 PM

300 oz plus,

645mg wouldnt even work in rock for me, maybe in grass or concrete flat.

i am 7955 upgrading to 7950

twisted bender · 09-29-2009, 10:55 PM

jr 8711 403oz torque at 6v or jr z9100t 370oz torque at 6v both have metal gears and aluminum cases and fully rebuildable

Pointman · 10-12-2009, 05:47 PM

hitech 645 works great and good price

life_livin · 10-12-2009, 07:07 PM

futaba s9157 is a beast
if you are getting a servo go for that one
just my $.02

1beatjeep · 10-12-2009, 07:57 PM

hitec hs 7950 th has 487 oz of torque

dub599 · 10-12-2009, 08:43 PM

futaba s9175. it will move my entire car sideways instead of not moving if my tires are bound up. do a lot of reasearch on what you buy. you will find alot of complaints about the JR's and hitecs getting sloppy or needing to replace parts after a month or two. so whats suggested to everyone to fix their problem a futaba servo. im only biased because i spent a ton of hours the last 2 weeks researching servos and electronics

CHAD DAD · 10-12-2009, 11:15 PM

DUDE.... If your a pimp the only way to go is the 7950 with a castle bec wired in turned up to 7 volts that is more power then you need

then you will just start ripping rod ends apart (that is super comp rig status!!!)

bruteforce · 11-04-2009, 03:15 PM

Holly crap guys, the stock servo is rated at like 90 oz I think, and it is pretty weak, but aren't you guys breaking stuff at 350-400+ oz?

BadRockNoCookie · 11-04-2009, 04:03 PM

This is all you will need:

Plenty of torque for rock crawling, without wasting your money by overdoing it.

This is what I've been running, and no issues. Granted, its not a comp rig, but for bashing around it seems to do the trick.
