aftermarket servo's is 222 oz./in at 0.06 sec to 60 degres

[reod12x2]

hey guys looking for a aftermarket servo that can go throught the rigors of being abel to go fast do speed runs and go track side in the future

im looking at the hi-tech hs-7940th

it can dothis (link)
and am woundering if this is enought for the rusty or are there better(a little less torque and abit less speed) for cheaper?


thanks guys

id take all the speed and power you can get for dirt racing.

I always wonder if you really notice an advantage with such a crazy fast servo. Since the VXL BEC is 6V, you don't get to the 0.06s when you feed the servo via that way.

With a Savöx 1258TG you get 0.08s and 166oz on 6V for less than half the price...

[sixshooterstang]

.08 and .06 isnt much id go with what peter suggested

[Petertje60]

on 6V it's even 0.08 compared to 0.07

That servo has a lot of torque, IMO more than you will ever need in a Rusty. I like a fast servo and do think you notice the speed more than the torque in a truck like a Rustler.

I have used many Hitec servos and have mixed feelings about them. I much prefer Ace servos. My son has far more trucks and servos than I do and he uses nothing but Ace, we have yet to have an Ace servo fail on us.

I have an Ace 1313 in my Rusty and a 1015 in my Pede 4x4.

Really nice servo, but yes, you can get something a bit lighter duty and save quite a bit of money. 125-150 oz. is plenty for a Rustler. And IMO, anything that's rated at .11 sec or lower is more than fast enough. I used to run a JR9100s in my T4 and it could get you into trouble if you weren't careful with steering input. That was .06 and 180oz. Used the same servo in my 1/8th buggy and it still didn't break a sweat.

[sixshooterstang]

the only thing that really needs that kind of torque is a single servo revo or maxx. or a 1.9 class crawler

Aren't you ok with the stock servo (2075) Because that's 0.14s and 125 oz/in and lets be honest more than enough. even on high traction surfaces the servo for me does it's job and for a rustler see no need in spending ridiculous amounts of money on something I don't need

[AbSoLooT1]

Those are some nice specs. But ur looking at over a hundred bucks for those specs from hi-Tech. U can get a Savox Servo, with equivalent specs to Hi-tech or JR, for half the price. I suggest the Savox 1257, or 1258.. 70 bucks, instead of like 140 for the Hi-tech, and they are terrific servos.

I personally will never go back tot he stock servo. They have no real torque, but above all else the plastic gears are terrible. Once my vehicle was upgraded so much, the Servo became my weakest link, and I had issues with it stripping the gears, or the screw that attaches the saver coming out, on a good bash.

You dont gotta pay over 100 bucks, u can get an awesome, very fast one for 70. My Rustler is running the 1257, and its super fast, and works excellent

I strongly disagree.. My stampede has 278, and its off the hook. Speeds are awesome under .10... Its one of those things u dont think u need, until u got it. Plus, 222 is really really low for a crawler... it needs in the 3-4 range.

Its one of those things that one u get u realize u cant live without. The Rustler becomes so much more agile with a high speed servo. around 150-200 tq @ 6 oz, and under .10 is ideal for a Rustler...

Well said by Peter. U totally dont need a 140 dollar Hi-tech servo. That I wil so agree... BUT.. a 67 dollar Savox 1257, or 1258tg is ideal... plus say goodbye to pesky stripped plastic gears with the Titanium gears. All for 67 bucks.

1258 .08 and 166 @ 6v

1257 .07 and 133 @ 6v

Both of those are great options

Food for thought -

I installed a Savox servo last night on a build and I had to replace it with a Hi-tec.

I am running a castle creation power combo with a TQi receiver and the Savox servo was pulling too much power from the ESC creating a huge glitch! My options are to either run a seperate BEC to power the servo or replace it with something that draws less current....it was cheaper for me to replace the Savox with a Hi-tec.

Just keep in mind, savox servos have a higher amp draw than most other servos and certain ESCs dont like that.

I upgraded the very very old Futaba S3003 (6.0V: 0.19 sec/60°) in my Bandit to an Alturn USA AAS-752MG (6.0V: 0.09 sec/60°) and the difference is substantial.

That's one of the downsides to those Savox servos that many owners seem to forget to mention. They have proven to be good servos, but there's a reason why they're cheaper than Hitec and other leading brands. On top of that, many of them are quite loud compared to comparable servos from bigger names.

Yeah, I would say that's a huge upgrade! Those standard servos are terribly slow. That 3003 is similar specs to the Traxxas 2055 (probably the same servo). You actually have to start turning before you get to the turn. And forget about taking a good line through any kind of tight switch-back sections. It just ain't gonna happen.

That's what frustrated me and prompted the upgrade.

[Petertje60]

Very valid point about the power consuming Savöx. For the record, I didn't leave that info away on purpose, but just didn't think of it. I had to add a separate BEC to be able to feed the Savöx sufficient.
Another valid point is the noise. It is very noisy when there is the smallest amount of stress on the wheels.

For the rest it is good material. Besides the power comsumption and noise, I never had a single issue. Quite durable servo.

[JayMcGill]

I know they arent a big name / big money servo, but I ran the EXI D226 in my Rustler for several months until I sold the truck. The servo has metal gears, is digital and coreless. The only issue I had with it was it was loud. But for $14 I was not complaining.

[RC-Fan]

hitec 645mg, 5645, futaba 3305, they are all good metal geared servos, nice upgrade for a good price.

Those Hitecs aren't really an upgrade over the Traxxas 2075. They have metal gears for durability, but they're slower than the 2075 and really don't have any more torque. However, they were a popular upgrade when Traxxas kits came with 2018 and 2055 servos.

[reod12x2]

sorry guys meant to reply sooner. but the system i plan on running when im done the build is the mmp.i know it has adjustible
voltage but do not know what amprage it can suply.on the other side a cc bec is around 25 bucks if needed

so most say the savox servo is a good one to get . and with that money saved equals more parts in my hand specialy around
50 compaired to 140
my only thing is i havent drove a rusty yet. so i dont know what it need as far as spec i know from 125 oz/in to 200 oz/in
but ya ya ya
i will be running it with the 4x4 bell crank. and is there a traxxas /aftermarket horn avalible

thanks guys for the replys

oh kaaaaaaay

so been looking at servos the past hour and its come down to the two

savox 1257tg servo
6v=0.07sec/60 degrees at 138oz/in
$70

or the

hitech hs 7965mg
6v=0.10sec/60degree at 138oz/in
$65

so if hi tech is the better compiany.
the hitech servo would be the better servo sept for the 0.03 sec/60 degree losse?
^and more efiecent?

[Petertje60]

Not sure if Hitec is the better company, neither if the little slower Hitec is more efficient.

Quality-wise I would say you can't go wrong with either.

That didn't help much to make a choice, did it?

Looking at wallet impact, the Hitec can work without a BEC so would be even cheaper.

[reod12x2]

okay hi tech it is
sides that 0.03 seconeds

+1. Both of those servos are excellent choices and a nice upgrade from the stock servo.
