1/8 Servo discussion
 

What are some of the best servos for 1/8 buggy and truggy. What makes servos good, like how much torque and speed for a buggy, and how much torque and speed for a truggy is ideal.

Get ready .....

Your about to find out they all break sooner or later , and specs are personal preference.

I always end up going back to HItec 7945 and 7955 servos. For buggy , truggy , monsters , nitro , I even used one in my stadium truck .

if you are looking for a buggy servo you need at least 15kg.cm torque, for truggy it is 20kg.cm or more. Speedwise, 0.1sec/60degree or a little less would be nice. i have savox 2274 servo which is priced and performed well, but there are so many good servos around.

Hitec 7955 is hard to beat. Around $80 after Tower coupon. I've been running that same 5955's and 7955's since 2008 or so. Some are starting to feel a bit rough but they keep ticking. Never saw the need to "upgrade" to ~$150 modern servos that people like to run when the 7955's can take up to 8.4v all day long.

I ran the 7955TG for awhile and then the 7950TH. great servos, and if you run in a vehicle that needs it, they have long leads so no extensions needed.

I recently changed over to the latest futaba servo, the S9372sv .

So far so good, loving the torque and speed of these servos as going back and forth between vehicles the speed diff was messing with my timing.

Been running a ProTek 130ss in my 1/8 buggy (pulled it from my last Tekno Short Course Truck)..ship shape..

I run the trackstar TS-900 on my 1/8 buggy for almost a year now taking a beat and still perfectly fine. Titanium gears, 258oz @ 0.09sec @7.4V. Best part is; that cost $34. I also use the TS-920 on the 4wd SCT. Difference is that the TS-920 is 181oz @ 0.07sec @ 7.4V but same price. And they have a one year replacement warranty.

So basically I have these specs as generally good standpoints for 1/8 buggy. Thank you, I'll keep that info for the near future if needed.

what spline do the trackstar servos have? any recommendations on one for 1/10 2wd buggy?

I switched my stuff to the new Futaba S9372sv like Cain mentioned earlier. Like them so far, wicked fast but smooth on 7.4V.

I also don't quit understand BECs and how to get them on different voltages, but I've heard of them

Depending on what ESC you are running its as simple as hooking the ESC up to your programmer or laptop or whatever and changing the BEC output from 6V to 7.4V. IMO all ESC's (especially 1/8th stuff) should have a HV BEC these days but some still don't. I have ran Tekin RX8 gen2 and Hobbywing XR8 in 1/8 stuff and both run HV servo's great.

Okay thanks. I'll have to check out trackstars stuff. Are they reasonably priced? I'm assuming they are sensorless

So I was lookin up servos that people commonly use for their buggies and came up with another question. Someone I saw was using a savox 1268SG, and as I was looking on the savox site I found the 2274 which has much better specs. I'm wondering why people don't use the 2274? It seems like twice the servo of most I've seen.

If I were to venture a guess, most likely they have had some problems with the cheaper Savox servos. Usually asking way too much for a 1258. Thus offputting them from trying a more expensive Savox.

I've had a couple 2274's, great servos. Problem is they are towards the price point most just spend slightly more for Futaba or something else. Spec wise I'd say the 2274 is very close to the Futaba 3952/3972.

The most crazy servo I own is the BK Servos BLS-8001. However I've found the gears just aren't enough for 1/8th duty. Followed by the Radiopost Black Signature Series.
