Servo recommendations
 

Can you give me the best servo recommendations for very high speed and very high torque to run non regulated on 2s lipo for truggy.

Im looking for speed .06 and torque over 450oz.

much appreciated!

Our 35kg low profile servo can easily meet those requirements, and the 35kg low profile, and 45kg are used by a number of our clients for Truggy.

Links to the specs below. The actual performance of our servos exceed our advertised specs, our 35kg actually perform at .06 seconds at 7.4v, and produces over 35kg. Links to our Speed and Torque test results below as well.

low profile for 1/8th? usually thats for 10th scale

Maybe others, but not ours, we developed these for 1/8th. We designed these with a case height of about 28mm rather than a traditional 26mm case, and we use the same brushless motors as our standard size servos. They are basically a more compact version of our standard servo, hence why they are so powerful, and fast. Our 25kg, and 15kg are even faster. All our customers that use our low profile servos use them for 1/8th Truggy, and Buggy as that is what they were designed for.

Did you even watch our test results?? Our 35kg produces over 35kg at 7.4v, and has a speed of .06 seconds. Our 35kg low profile tested at 38kg which is over 500oz of torque. More than enough for any 1/8th scale application.

We even have a 45kg servo low profile which is also popular for 1/8 Truggy, and these produce well over 45kg, around 650oz of torque. Here are the test results for our 45kg low profile, and these were sent to Gary and Mike over at VRP Pistons, also known as Vision Racing Products. They use our servos in 1/8 Truggy, and Buggy.

Those AMR servos look nice, but this is the first I've heard of them. I prefer brands like Hitec, Blue Bird, and Savox. What I like about Hitec's is that if something goes wrong, you send it in and they fix it. I have all 3 brands in my larger planes, buggies, and other RC. I usually skimp on price if the servo is going into a cheapo smaller plane, but will pony up the extra price for something I care if I lose it. I put a Hitec 7955TG in my Losi 8ight 12 years ago and it still is working fine. If it ever fails, I'll send it in. I do know guys that run the 7955TG unregulated and they do fine. I don't because 8th scale doesn't need anymore torque. The newer one is the 7950TH which is $20 more and can take unregulated. Come back to this thread and let us know what you picked.

Unfortunately those 3 brands you listed have never tested at their advertised specs, when we tested them, however out of the 3 the Bluebird was simply terrible, The Bluebird averaged only half of what they advertise, supposed to produce 47kg at 7.4v, yet didn't even hit 40kg, and only averaged 25kg. Let's just say after I did my demonstration at our local track, the guys that used to recommend them, and run them didn't do so anymore. As I always say, the results speak for themselves. I always like to add, our torque tester is pretty industry standard, however if these companies have some sort of magic torque tester, and they produce the advertised torque they state, then imagine what our servos would produce on that same machine if ours are already more powerful than the brands we have tested on our equipment.

Bluebird Brushless Servo Torque Test model BLS-M45B. By the way, this servo failed in less than 2 weeks, and the one I tested was the new one they gave me only after I waited almost 2 months for a replacement from them. I literally had to jump thru hoops to get them to replace it, and had to have local guys at my track vouch that it was installed correctly, and since it was an intermittent issue I had to drive my car till it started to act up and get it on video as well which caused unnecessary damage to my car as I could not get it to act up on the bench. Even with a rubber band it would not return to neutral, so basically the car would get stuck at a certain throttle position, and my car would go running wild. Only till I caught the issue on video they would replace it, even though I had purchased it less than 2 weeks before it acting up. I have a ton more videos of various servos models, and I will post them up in our channel, as I don't want to just upload everything all at once.

Maybe check out Fantoms programmable servos. Their website doesn't say alot about whats programmable, but when I talked to Troy (one of the owners) they are super adjustable like an esc. You can change the curve in the servo its self, speed and other stuff. I have 2 coming for my 1/10 stuff when they are back in stock. I'm excited to try them.

Fantom 1/8 programmable servo

Looking at the popular Savox brand:
Savox - Servo - SV-1260MG - Digital - High Voltage - Coreless Motor - Metal Gear » Coreless Motor » Servos » SAVOX-SERVO.COM
But that is something you also could have found by just visiting some websites and reading the specs. I know, letting others do the job is much easier.

But really, do you need such a fast servo on a big heavy truggy? When you lower the specs on the speed to 0.1 sec at 60 degrees you will find many (affordable) options.

I've experienced a lot of failures over many popular brands and have grown to trust the following 2 servos for 1/8 truggy where neither of these have caused any failures for me over the past several years:

https://shopjtp.com/products/jtp-ct3-1-8-servo

https://dialedhobbies.com/srt-bh9027...s-servo-detail

Hitec 9381.

Watch out on the specs. The speed spec mentioned in the OP, would be a servo geared for speed. It'll slow down under load in a truggy. You want a high torque servo in truggy.

Hitec d945 would fit the OP spec well, though.

When you see absurd speed and torque specs, it's BS. Better to see what people are using, not what specs they're chasing.

A Tekin t300 would be a good choice too.

Well there you go....Fantom, JTP, SRT, and AMR....all brands mentioned in this thread around $150, all brands I am just now hearing about. MMM...I wonder what they have in common. It would not surprise me if a few of those are built at the same factory. Somehow they have figured out a magical servo recipe that has eluded the main brands who have been doing it for 50 years.

Everyone will have their own experiences and failures of various brands. And once you have a catastrophic failure that has taken out a $3000 plane, you may never buy that brand again. I've had 2 Hitec failures....they were used and not even under warranty. Sent them both in and they were repaired or replaced for free. How could I have the same confidence in Fantom, JTP, SRT, or AMR to do the same? What reason could I possibly have to spend $150 on an unknown brand? No offense to any of these brands......how could there be an offense when I had never heard of them.

Fantom and SRT are established brands. The other 2 I've not heard of until now.

Fantom is an established motor Co. Their esc is already obsolete. So they could easily drop servos in the near future.

The other niche companies come and go. I dont blame anyone for avoiding them.

Making a quality servo ain't easy. I put Hitecs in all my planes. Digital, metal gear only.

Literally all their stuff is new, the oldest thing they have now is their stock motor. As I said I talked to Troy a few weeks ago at the track for quite a while. I brought up their old esc's and he started talking about all the R&D they did on them and the servos. Which is why I ended up ordering their stuff.

No offense at all. I will simply state this. Many of the brands mentioned here didn't meet the advertised specs when I tested them. Not only do ours meet our advertised specs, but exceed them. Sure they might be around longer than us, but are they delivering what is advertised? I let the data do the talking , and we will continue to test various brands and upload them to our channel. I spent thousands of dollars buying different high-end and low end models and will post the results gradually so we have new content. It doesn't make sense to post all of them at once. I can atleast do business with the peace of mind I am delivery exactly what clients are paying for and I test our servos frequently. I even post the results of those test on our channel. Good luck with whatever you decide.

You seem to be speaking on behalf of the manufacturer. Without an independent test to verify, or you publishing the data with methodology as well, your claims should equally be taken with a pinch of salt. Otherwise your post just reads like "you can't trust anybody but us". That's a pretty tall ask from a brand that few have heard of.

:lol: His torque tests use 3d printed servo holders and theres no methodology video on what he does to ensure consistency or accurate testing. Heck I just watched his first torque test video on the cannel and you can see the 3d printed mount flexing in the middle of the video. Its REALLY hard to tell with the camera moving, but if you focus on the silver screws and look at the difference in how the grey part moves you can see it. And dont tell me thats impossible because RC is all about having fast reactions and peripheral vision.

Does he have valid points that its hard for many servos especially cheap ones to hit their advertised specs? Sure! Do I trust his testing that explains nothing, uses flexible 3d printed parts and is monitarily incentivsed? Nope not at all!

Oh in one video they're sending servos to VRP so they test them before shipping. OK thats nice, testing before shipping. Does everyone get that treatment? Who knows. But he just did a few random tests, not repeatedly hitting it like with the powerHD servo video where he shows it slows down and gets inconsisent and hot. Or at least he says it heats up and thats the issue. Is it just internal temp and not externally measureable? Who knows, just buy AMR servos. Oh and ignore the extreme flexing on the 3d printed servo mount.

Sounds just like Pro Performance. That guy claimed they're so much better than anything else, and even threatened to post some details about the mosfets or components he was using.....but never did. Probably found out it was the same or similar to what everyone else was using in the esc's made by the same parent manufacturer.

If it lifts it, it lifts it. Flex in the mounting apparatus, won't matter much.

That would mess up speed and accuracy testing for sure though.

I'd be willing to test one in 1/8 Ebuggy. But I don't have the budget to buy and test another brand of servos. It's nice having that budgetary issue nipped. (And esc's, and batteries)

The funny thing is, pattern aircraft rarely have servos faster than 0.14. And those guys have more precision than anything we operate. They do just fine.

Some flex is indeed no problem as long it is blocked at some point, then the hold power of the servo is real.

Keep in mind that with airplanes there is no direct contact with something solid that cars do have with the tires on the ground. The airflow over a rudder already gives a small delay depending the size of the rudder and also the weight of the airplane. A good grippy car will always react faster with a faster servo. But grip and offroad are 2 thing that can not be named together so a fast steer servo has no sense when the low grip and the heavy chassis always start with some understeer.
As mentioned before I think 0.1 sec is fast enough and will give more and affordable options

I may be old fashion, but there is only one servo manufacturer I will use, Futaba. I've been using Futaba servos since I began RC racing in 1982 and I have never had any servo problems.

Nitro pro or nothing bro I use the ct1 2 3... in truck and in buggy iv use the r2 shorties or the same
Now I remember y I stop using this page nothing works

Nitropro servos are incredible. I use the FK-N500FST and the 550FST servos. I've had the same servos in my Truggy's that I purchased back in early 2019 and they are still going strong w/ null issues. Bought a few to have as spares and never needed them.

Incredible? Really? What is the draw on buying a non name brand servo that looks like it was made at the same plant as other non name brand servos and noone has ever heard of? I am not being facetious, I really want to know what the draw is on spending that kind of money on that kind of a servo. You aren't the only one who is doing it....look at all the other brands mentioned in this thread. What was it that made you get this Nitropro servo over a branded servo. It would be like me buying a Hyundai for the same price as a Mercedes. Before you bought your Nitropro servo, did you research the brand and find out something amazing......or in your words "incredible"? I did go look at these servos and they have some puurrty graphics on them. Is that what you liked about them?

I actually have a metal one, and can easily show in our videos the torque results will be the same lol. The torque drop you see in many of the videos of various brands we have tested will be the same as they heat up as well peak torque created. If you think along those lines then clearly my servos would even more powerful. Remember the test are all done on the same torque tester. Our consistent torque production as our servos get hot would not change regardless of fixture. Nor will a metal fixure make up for servos producing half the torque they advertise.

My servos produce the torque as advertised and they will do the same on a metal fixture.

What about the speed test we recently did which the servo is advertised as .06, yet only produced .10 at 7.4v?? If you guys are okay with giving these people your hard earned cash so be it. It's a free country. Yet ours meets the mark in the same video without a single cut thru the video. Our speed tester produces the same speed results as the equipment in our factory. On top of that they use the same torque tester. Where do you think our tester came from lol. Again regardless of the fixture our servos meet the specs that we advertise while others do not, period. If a metal fixture added 5kg to one servo it would add 5kg to all the servos tested. My videos are transparent and the results can be interpreted how you want...in the end the data is the data.

You do realize most of these brands these days don't even have their own equipment to check what they are ordering from overseas with their name on it lol. Guys are just gullible enough to take their word for it. We have our equipment and our factory uses the same so our results are consistent with each other. We even have a laser speed tester at our factory which is not portable, however produce the same test results as our portable unit we take to races.

Just for you I will switch it out to our metal fixture, and your assumptions will be proven wrong. What then, you going to continue to stick up for these brands who can't deliver?? Probably right cause they been around longer than us haha. We still selling our servos regardless lol.

I often get much enjoyment out of reading your uneducated posts and comments about my company and I typically don’t respond to them but this time I will fill you in….
Pro Performance servos are highly advanced and were the first in our country to be able to utilize the Sanwa SXR mode,before Sanwa’s own compatible servos were even available in the states.Very expensive debugging equipment was purchased and special PCB’s were developed just for this purpose.

Why would I “threaten” to post anything pertinent as to what gives our electronics a distinct advantage for our competition only to read here,it makes no sense.

No need for any debate however since our race results speak for themselves and our equipment has been in the front of every major event in the hands of different drivers since the beginning.

But please enjoy your AGF rebranded (Fantom) servos as I personally look forward to smoking you on your home track (or any track) with the most DIALED equipment from #TheRealRaceShop

It's worth clarifying that AGF servos are junk, more info here:
https://www.rcgroups.com/forums/show...t-AGFRC-Servos

In that thread I explain how NitroPro has upgraded all the shortcomings from the AGF branded crap and is far higher quality. I refuse to buy a servo that doesn't offer at least a 1 year warranty which is why I listed NitroPro as a recommended servo above, and the other servo that I recommended was from SRT and they offer a 5 year warranty!

I will never buy a servo from overseas again and will only deal with a USA distributor who offers warranty protection. If anyone is selling a servo with only a 30-90 day warranty, then I would NOT recommend any of those brands.

Ok heres the thing, you recently started selling servos and are testing all the competitions and posting tests. Your goal is to sell your servos so you're financially motivated to make your servos look good. In PC hardware testing, the people at the top have been doing it for years and have posted videos on how they test and why they test. Is servo testing as complicated? No but you just came out of the blue and are talking bad about every other brand. Of course theres plenty that don't meet their specs, cheaper stuff is cheaper for a reason. But I haven't really seen any higher end racing brands posted yet, but I do understand the youtube game.

The speed tests are going to show some seriously bad servos, thats understandable. But Idk why I should trust your tests, again you're motivated to show yours in a better light. You've posted some very interesting "data" but taking it at face value with no skepticism is not smart. But yeah keep acting high and mighty and don't really give us a reason to trust your results. You're just saying "trust me" and not giving any reason too.

But yeah how dare I question a 3d printed mount that shows flexing from the start.

You were called out in some other thread, and you were going to post some info about transistors or something that proved how much better your escs were. You know, proof your marketing isnt hot air. You never responded. I'd dig it up but I need to be doing other stuff, but if someone else wants to go through your post history be my guest. It'll be obvious. I've talked to average drivers that run your stuff and the impression I get that its nice. No idea if theres more punch or power or rpm in a stock motor, but they arent any worse than other high end race escs.

Dakota winning with your stuff hardly matters, he won with the 22-4 for years and thats a design that originated in the 90s. He didnt super hot at the worlds either. He'd likely be in almost exactly the same position with a HW, Fantom or Reedy esc. ESC differences are some of the most hard to quantify differences, so forgive us if most of us are skeptical that X product is just sooo much better than anything else you've ever driven!

Do you guys have valid points that many products are complete scams and their advertised specs are way off? Yeah sure. But why wouldn't that also apply to what you're selling? Have you made some improvements in stuff you're selling? Yeah sure. Im sure the differences are nice compared to some things, but your marketing hype is not going to win everyone over. Theres lots of that flying around so dont be surprised when you're not the exception to that.

We were also promised that Dakota would win the worlds this year because the ESC is that good.

[QUOTE=Alexv2024;16037213]You were called out in some other thread, and you were going to post some info about transistors or something that proved how much better your escs were.
“Called out” or asked by someone (yourself) information that you do not need to know there is a difference
Dakota winning with your stuff hardly matters, he won with the 22-4 for years
I believe that it matters to him and that he can run any brand of esc’s that he chooses but you do know that out of the 13 National Championships our company has won in our first 5 years wasn’t all his wins correct? I’ll wait while you let me know if any other rc company has won that many in their first 5 years since the beginning of the sport. Not to mention nearly every other major race in our country

Owned by the CEO!
btw the new Pro Performance offroad carpet servo is amazing, new hot laps along with top 5/top 10 times tonight!

At the track my Puurrty Savox died on (as did quite a few of themas well as a couple Hitech and Futaba servos in the past) me so my buddy let me borrow one of his spare Nitropro servos and I liked it so he offered to sell it to me and that was several years ago with Null issues and is still in use in my old RC8T3.1. Nitropro is pretty widely known in the southeast and I know quite a bit of racers who use them and just because you have never heard of them doesn't make then bad. Ive gone through many servo brands in my time w/ RC and these are the best I've tried. They are strong and reliable and at a decent price, and yes, them purity graphics are a nice touch. To each their own as I think they are "incredible" servos.

   "an almost incredible tale of triumph and tragedy".....That is what I was thinking reading your incredible story. So you have had servos that have failed and servos that are working great. Everyone in the hobby has had the same experience. It may sound incredulous but it's true. I hope I have captured the incredulousness of the subject. /
   

Some passionate people in here for sure.

I find Savox & SRT provide pretty good value for mid range servos.

For high end stuff I always go KO Propo

I've not tried them but I've had Tekin servos recommend a few times and the quality and specs looks good

Yup

This thread is :lol:

They look similar to yantrs servos

Yours low profile servos are not too big and heavy weight?
The servo 15LPBLM size is 40x20x40.5 and weight is 73 g
I compared with ans MKS HBL575 SL X6 where size is 40x23.5x23.1 and the weight is 53.5 g
The torque is similar but if you run with an 1/10 touring car the small dimensions is mandatory 440.5 x 20.5 x 23.1 mm0.5 x 20.5 x 23.1 mm40.5 x 20.5 x 23.1 mm

Looks like their site has typos on the dimensions. Their low profile and standard sized servos all list the same size and weight despite being clearly different visually. Also that MKS is an ultra low profile, you don't need to have a servo that small for TC.

Seeking opinions:

I completed a new TLR 22 SCT 5.0 Vision Racing Conversion at the end of summer for the indoor winter carpet season. I typically run Sanwa PGS servos in my vehicles. So when I built the SCT I threw in the Sanwa I had on the shelf which happened to be a Sanwa PGS-XB II. I also had a new Pro Performance XTS600-HT. I won’t dig too deep into the initial, but it was heavily based on having a consistent brand in my equipment.

With that said, is it worth pulling out the PGS-XB II in favor of the XTS600-HT?

(I may eventually pull the PGS-XB II for a 1/8 eBuggy down the road anyway.)

Let the opinions fly!
