Anyone running the new brushless servos?

How do they rate and are they worth the money?

Savox SB-2271SG

I am looking at the above for my 1/8 scale buggy?

Running a 1258 but am thinking it might be a little weak on the torque side.

1258 is plenty for 1/8 buggy

If you want a little more run the SC-1267MG and save some $

the msrp on the new bruhless servos are 179.99, we will come out the street price soon. The brushless servos are awesome. And if you looking for a good servo for your buggy a 1267 or 1268 is a good choice.

Hey guys,

I got myself a 1258 and a 1256.

The steering servo (1256) doesnt buzz when turned on in center position but the throttle servo (1258) keeps buzzing even when not using throttle or brakes.

Ive played with it for the last 3 hours, servo doesnt buzz but soon as i put horn on, it buzzles. Tried most the End Point Settings + Trim on the controller (airtronics m11x) and still no go.

Is the 1258 suppose to buzz/be noisey on nuetual position for a throttle servo??

yes because of the spring presure from the spring on you linkage... digital servos will always trying to find center.. with pressure on the servo horn from the spring the servo is just trying to find center..

Oh Hmm, will this drain the battery real badly? Just got the servos today and haven't had chance to test them at the tracks yet.

Nope. On a 1300 life battery i get 1.5 hours of runtime before i need to charge reciever pack

Have the 1256/1258 servos in my buggy.

The steering one though seems to stop working properly after 5 minutes on my JQ buggy. At first I though it might be a dud life pack, so bought a new nimh pack to go in it. Charged it up and went for a run today, only to find that after 5 minutes the steering was gone. Is this the sign of a servo about to give up completely, or are there some other things I need to check? The steering is nice and free with no binding, so it shouldnt be under excessive load.

Any thing I should check, and can anyone diagnose my problem outlined above?

edit: I check the spacing and its got great clearence above the chassis, so it shouldnt be heat related either.

Savox 1256tg or Spektrum s8000? .15 doesn't seem fast enough in 8th buggy, coming from a jr z9100s for steering...

go with savox 1258

I'm a little confused on something. Some servos have different specs for different voltages.

For example the 1268 -

Torque: @6.0v - 208 oz-in. (13 kg-cm) / @7.4v - 361oz-in. (26 kg-cm)
Speed: @6.0v - 0.13sec/60° / @7.4v - 0.11sec/60°


My question is, what do I have to do to get the 0.11sec/361oz out of the servo? Is it as simple as setting the voltage to 7.4v on a BEC? Or do I have to do something else? I'm using a MMM esc and I know I'll have to get the Castle BEC to up the voltage.

I think to get the 7.4 rating and speed and torque that comes with it you need to run a lipo rx pack. Don't quote me but that is the high voltage outputs

Looking at the Savox servos for my Associated B4.1
When you get the servo, are installation instructions included?
I'm concerned about getting the proper travel limits and the thing lined up properly.

I just put a Savox 1258TG into my XXX-SCT and it will not stop buzzing. I have messed with the end points and checked to make sure the servo is zeroed, and it doesnt help at all. What is going on? I have heard a lot of great things about Savox servos but as for right now.......not very happy!

For the first part, all you have to do is use the same mounts and direction as the one in your b4. also you might have to shim it a bit. Just use the instructions forth b4 and you'll be ok.

For the second one, it will buzz because it always going to find the center of where you put it at. If you pic up the front of your car/truck and steer one way and let it go back to center it won't buzz.
