So last few years me and the son have been running the Traxxas 4tecs, not racing and things are going decent, BUT I did the cheap dad thing and bought amazon servos being DS3225mg. Paid like 30 bucks for the pair what a steal. Then I talked to one of the guys who was running a Savox, don't remember the model. Was very fast! So what are some high speed servos that people have used, wont break the bank(wife) but will take abuse, and not cost like $100 a piece! Thanks guys.

The faster you go, the more expensive the servos can be. And sadly, servos are pricey these days. There are so many options and brands out there, it's hard to even know which ones are best anymore. Savox is a good brand, and Hitec is another brand I've used quite a bit. Protek (Amain brand) seems to be producing some good stuff, but I've never used them, and they are likely out of your budget.

Here are some high speed servos, but pay attention to voltage requirements. Depending on what voltage the BEC puts out on your ESC will determine what servo will be best. Or you could go with a Castle 10A adjustable external BEC and just go for the fastest servo you can get for your money.

Just know that Savox servos can be power hungry, and some of them actually require an external BEC (not integrated into the ESC) to deliver cleaner power to them than most internal BEC's can provide. Otherwise you will experience brown outs where the servo stops functioning.

If you're running the stock Traxxas ESC's, I would definitely go with an external BEC to run higher voltage servos. More voltage = more speed. But getting that and a programmer is going to add around $40-$50 to your cost.

This one is .09sec/60° on 6v, and can handle 8.4v, so it would be closer to .05sec/60° or even faster on 8.4v. But I bet this one is going to need an external BEC.

Quick, and fairly cheap, but Ecopower servos seem to be a bit hit or miss on getting a good one.

Shopping around will be your best bet. Look at reviews. If you find something you want advice on, ask.
 
Throw a beefier BEC in there and run the servo you got at 7.4v. If it gives up the magic smoke or starts glitching things out, then look into higher end options and run them at 8.4v. You likely won't gain very much performance from a better servo running the stock BEC in the stock traxxas ESC.

They have low voltage servo's out there with impressive specs, but they're few and far between(and expensive). Often times the specs are really overinflated as well. I run my 35kg DSServo's at 7.4v with no issues and it really woke them up compared to the 6.0v most people push through them. I've tried 8.4v, but that's when they start having issues with centering after a while. One nice thing about cheap servo's, is you can abuse them without feeling guilty. Make them things put in some work. When the time comes for a higher end servo, you'll be in a better spot to actually use the performance it offers.
 
I have great luck with amazon servos, not so much with Savox.
I have heard that before about Savox. I've never had one fail, except maybe on our 6s Kraton which hit a tree going full blast. Have yet to pull it apart and see if it's just the saver that took a dump, which I am pretty positive it has, because the servo turns, but the wheels don't.

I have seen the same thing with Ecopower servos for the SCX24. I have two of them that are both quick and powerful, but others have had trouble with them and their other standard servos.

I've never destroyed a cheap Amazon servo either. I better go find some wood to knock on 😝
 
Power HD B5S. 80ish bucks. Sometimes cheaper
.065/60 at 6v. 0.055/60 at 7.4. absolutely the best servo for the speed for the price. Nothing will beat it.

I think I seen ProTek being mentioned. They're alright. Decent. Although the high end ones I heard some of my club race buddies has theirs fail on them (electrical problems). Ecopower is also a budget decent brand. Although I burnt up 2 of their micro servos before.

Savox is really good but pricey. And savox has their odd sounds and beeps. Lol.

Cheap Amazon servos are decent to get you up and running but after a while bc most are brushed (unless it's brushless 9imod ones which are really good for the price), most are brushed, get loud overtime, sometimes gets stiff to turn and eventually seize up. I had that happen once on a OmG 20kg pro servo.

thanks for the replys, sory i should have said power systems. flysky nobles and bl2s traxxas, never messed with an aux power source for a servo, looked into agf last night, i have a programmable servo for a buggy that seems ok, so idk
 
I use cheap Amazon feetec servos and they're pretty fast for what they are. Only reason I've had one break is because my friend ran over the front end of my slash with his surron. Didnt break anything else, just the servo. I bought some second hand ones from @xjtorc and the eco power one was fast and powerful. Look into feetec and second hand stuff. The feetec I run is rated for up to 7.4v, but runs great in a 6.0v. About $15-20 per servo.

Oh yeah! Forgot to mention that they do use metal gears and have a good case and mounting plate.

I really wouldn't worry about speed too much. I usually have to lower the speed of my fast servos for better stability anyways. I think materials, torque and water resistance, if that's needed, are more important than speed for most rigs.
 
Food For Thought

I don't know what your budget limit is, but once I start looking at all the middle tier servos... I will also look for spare gear sets availability. Generally, if I can't find a spare gear set for a particular servo, that servo won't make it onto my wish list.
 
Check out Protek, EcoPower, & Hi Tec

I run Protek in everything except for 1 rig that has Reefs.

If you want to keep the cost down brushless & waterproof servos are great but more expensive. I would definitely go for metal gear.
